When an aging pet passes on, one of the things you might notice when the pain of loss loses its sharpest edge is that you're not seeing veterinarians as often as you were. And if those veterinarians are the kind of people you like and whose work you respect, you might even miss seeing them. Maybe not enough to go in just to say hello, but certainly enough to appreciate the good care that your pet received throughout his life.

That's the way I feel about my veterinarians. They got Andy off to a great start as a puppy and helped keep him healthy over what was a very good, long life -- almost 16 years. It's hard to say who impressed me more -- our "regular" veterinarian or the specialists, which at various times over the years included a cardiologist, an internist and a surgeon toward the end. Yet, it was a veterinary acupuncturist who brought real quality to the old dog's life. She gave Andy relief from the often-painful burdens of old age and opened my eyes to the possibilities of alternative medicine.

Although not as many specialists exist in veterinary medicine as in human medicine, the kinds and the number of veterinary experts grow every year. And that's good news for our pets.

Current companion-animal specialties include such "system" areas of expertise as cardiology, dentistry, dermatology and oncology. There are also species specialists, such as those veterinarians certified as experts on bird health. Veterinary behaviorists are becoming more common as well, helping people and their pets work through such problems as house-soiling or separation anxiety with the aid of medication and behavior-modification techniques. And finally, there are those veterinarians who practice alternative or complementary care, including acupuncture, herbal therapy and homeopathy.

System specialties usually require additional study in a two- to five-year residency program, followed by a rigorous examination. These certifications are handled by a board such as the American College of Veterinary Internal Medicine, which is why certified specialists are sometimes referred to as "boarded" or "board-certified."

For veterinarians already in practice, the American Board of Veterinary Practitioners also offers specialty certifications, including those in feline and avian practice. The certifications also require passing a difficult examination.

There's no mandatory certification for alternative or complementary veterinary medicine -- any veterinarian can start calling himself "alternative," but services offered and skill levels will vary. That doesn't mean you should avoid such practitioners, but you should be aware of the potential for problems. (More information on alternative veterinary medicine can be found on the AltVetMed Web site, at www.altvetmed.com.)

Many large urban areas support independent specialists or specialty practices, but in less populated areas you're more likely to find a full complement of specialists at the closest university with a school of veterinary medicine.

Only veterinarians who are board-certified are allowed to call themselves "specialists," although others may stress a special interest in a particular area of medicine in their practice marketing. As my "Birds for Dummies" co-author Dr. Brian Speer points out, some people who take a special interest in an area of medicine become very good indeed, even without the official credentials. One of only a handful of veterinarians certified as an avian specialist in both North America and Europe, Speer has lectured all over the world and seen what sort of care is out there for pet birds -- good and bad from specialists and non-specialists alike.

If you believe your pet has a problem that could use the expertise of a specialist, talk to your veterinarian about a referral. If you have a cooperative relationship with a good veterinarian, calling in a specialist is never a problem.

If your veterinarian is reluctant to refer you, remember that the final decision about your pet's care is always yours. If you want to see a specialist you should do so even if your veterinarian disagrees. Keep the lines of communication open with your veterinarian if you can, but realize that your pet's care is your responsibility and seek a second option or specialist on your own.

In Andy's case, the cooperation between his regular veterinarian and his veterinary acupuncturist could not have been better. They worked together, respected what each other did, and were both there with me to say goodbye when the time came.

Knowing Andy received the best care possible from all his veterinarians really helps to ease the pain of losing him. His was a good, long life, and I have no regrets.

The University of California, Davis, is home to what is considered to be one of the best schools of veterinary medicine in the world. I may be a little biased because this important resource for animal lovers has always been next to my hometown, but I've been to more than a few veterinary schools in the last few years and they always make me appreciate UCD's more. The UCD School of Veterinary Medicine Web site (www.vetmed.ucdavis.edu) provides a good overview of the school and its programs, along with information on its Veterinary Medical Teaching Hospital, where the best in veterinary medicine saves lives every day.

Overuse of oil-based hairball remedies can interfere with your cat's absorption of some important nutrients -- fat-soluble vitamins A, D, E and K. Talk to your veterinarian about your cat's hairball problems, and be sure not to overdo any medication you're sent home with.

A great alternative to commercial hairball remedies is canned pumpkin. Regularly adding a teaspoon or so to your cat's diet is a safe, inexpensive way to deal with hairballs. If your cat won't eat the stuff undoctored, try mixing it into canned cat food, or with the juice from water-packed tuna.

QUESTIONS FROM THE PACK

Q: I recently adopted a Labrador puppy. I'd eventually like to take her on my daily jog, and I'd like to know when she'll be mature enough, and if I'll need to work her up to the full four-mile distance. I jog a relatively easy 10-minute mile pace. -- K.D., via e-mail

A: According to Dr. Robert Richardson, a Sacramento, Calif., veterinarian who's well-known for his expertise in orthopedic surgery, you need to wait a while before putting the miles on that pup.

Richardson says an 8-month-old dog can safely manage only a one- to two-mile run at a relatively slow pace -- and that's if the animal is perfectly sound.

A puppy who's 8 months old is just past the usual growth spurts, says Richardson, who cautions that before that age a puppy's cartilage is very soft and easily damaged.

If you push your developing pup, or ask a dog with joint problems to run at all, you could be risking serious problems down the road. Consult your own veterinarian for a more precise assessment of your dog's suitability as a running partner.

Q: My husband has a meticulously restored classic Porsche he keeps on a concrete pad behind our garage, the car carefully protected by a fitted-cloth cover. A cat has taken to sleeping on the cover. While my husband doesn't like this, I've convinced him that it's no big deal.

Lately, though, the cat has started sharpening its claws on the corners of the cover, and the fabric is taking a beating as a result. The cover wasn't cheap, and the destruction is getting on my husband's nerves.

My husband's idea of dealing with this problem involves a gun, but I would like another alternative. Any suggestions for a non-harmful way to get the cat to keep its claws to itself? -- G.S., via e-mail

A: Cats hate to touch sticky material, so if you put double-sided tape on the areas where the clawing is causing damage, you ought to be able to fix the problem.

You can buy double-sided tape at the hardware or home-supply store. Or check out a pet-supply store for a product called Sticky Paws, double-sided strips that are designed to solve just such a problem. (If you can't find Sticky Paws locally, you can order the product direct from the manufacturer, at www.stickypaws.com or 1-888-697-2873.) I'd test out a small area before applying tape or the strips in great quantity.

And because you know a cat is sleeping on and around the cars, make sure you thump on the hood to scare him away before starting up any of your vehicles. Some cats like to sleep up against engines as they cool, which is a pretty dangerous place to be when the key is turned.

Every now and then you'll run across a product that seems so useful that before long you don't know how you ever lived without it. The retractable, reel-type leash (the Flexi is probably the most popular brand) is one such product.

I love my Flexi leashes. When I was driving cross-country last year, the product allowed me to give my dogs up to 30 feet of leash to stretch their legs at roadside rest stops, while keeping them safe from 80 mph traffic that barreled by not 100 yards away. My dogs are responsive to voice commands, but I don't risk them being off-leash in any but the safest areas -- which means I use the Flexi a great deal.

But every piece of equipment has its limits and its rules for safety that can result in great peril if they are disregarded. These leashes are no exception, and lately I've been getting a lot of sad reports from people who relied on the product for more than it was designed to do.

The Flexi is not designed for use with an untrained dog. A dog who pulls at the leash or refuses to come when called back from the end of the leash is at risk for injuring himself, his owner or an innocent bystander. This is not the fault of either the leash or the dog. It's an error on the part of the dog's owner in choosing the wrong piece of equipment.

How can a dog get in trouble on a leash? You'd be surprised. Some dogs have hurt themselves hitting the end of the long leash at full speed, and not having it give way (which is also pretty tough on the human holding the handle). Other dogs have bitten people or other pets, or hurt themselves, after getting too far away on the leash before the handler has time to reel them in, or by pulling the leash out of the owner's hand when reaching the end of the line.

Trainers have been sounding the alarm about the first problem for a while now, especially when the reel-type leash is paired with another recent development in canine control, the head halter. Although reports of injuries are anecdotal, it's not difficult to imagine the problems that can result if a large, strong dog is stopped suddenly by pressure on his neck, or by having his head whipped around by a halter around his muzzle.

As for the other problem -- a dog getting into trouble while at the end of the leash -- I've received a number of such reports in just the last few weeks. I witnessed this at a park once, when a boisterous young shepherd mix hit the end of the line so hard she jerked the handle out of her owner's hand. The reel then retracted the line close behind her, the handle bouncing on the pavement behind the dog and frightening her into a full-fledged panic run that ended with a sickening thud when she was hit by a car.

Perhaps the strangest case I've heard involves a Welsh corgi who ran out of an elevator just as the doors where closing. The elevator went up two flights before the dog's owner got it to stop. In the meantime, the retractable leash extended to its maximum length and then pulled the dog up to the top of the elevator door, suspending him by his neck until someone could get him disconnected. Amazingly, he suffered nothing more than a bruising.

The company that makes the Flexi is aware of the potential problems, and highlights cautionary information in its packages and on its Web site (www.flexiusa.com). If you own this product, you'd do well to read the manufacturer's advice before using it again.

If your dog is out of control, you need a trainer, not a retractable leash. Don't risk injury to yourself or your dog by using this otherwise marvelous product in a way for which it wasn't designed.

I've always found appeal in the Abyssinian, a lovely cat with large eyes and a distinctive ticked coat in which each hair is banded with colors. The breed's elegant and graceful physical appearance, combined with a friendly and outgoing personality that's sometimes described as "dog-like," makes the Aby one cat who'll always catch my eye. The Cat Fanciers' Association offers a good overview of the breed, with a page (www.cfainc.org/breeds/profiles/abyssinian.html) that reveals the breed's history, plus links to recommended reading on this gorgeous cat.

THE SCOOP

Years ago I was visiting a friend's house when she complained how disobedient her dog was. The dog, a sweet-natured cocker spaniel, was sitting on the couch beside me when her owner commanded her, "Down!" The dog immediately dropped into a down and was yelled at for her obedience. By "down," the owner didn't mean for the dog to lie down, but rather to get off the couch.

This is why I prefer to teach the command "off" when asking dogs to remove their furry fannies from furniture or beds. It's less confusing and more effective to teach the dog different commands. It's hard for a dog to understand English at all, much less find shades of meaning in different contexts.

QUESTIONS FROM THE PACK

Q: I have two 2-year-old cats, a brother and sister, and I am thinking of getting a Border-collie puppy. Is this a good idea? I don't want the cats to be hiding under the bed or not being social anymore. I don't want to get the puppy, then realize I made a mistake later. -- J.D. , via e-mail

A: While your cats almost certainly would not vote for adding a puppy to the household, they're young enough that they probably will adjust in time.

Before you add any puppy or dog, be sure to set up a separate area where the cats can feel safe, a no-dogs-allowed room with food, water, litter box, scratching post and more. You may have to keep the cats shut up in that area for a week or two after bringing home the dog, and then put a baby-gate over the door to allow the cats to be away from the dog when they want to be.

Locking the cats up doesn't seem fair to many people, since the cats were there first. But feline behavior experts say cats adjust better to change if provided with a small, quiet area that's just for them during social upheavals such as moving or adding new people or pets to the household.

Now, about that puppy.

The Border collie -- an intense, athletic and highly intelligent animal -- is really not well-suited for the average pet home. They have high requirements when it comes to keeping their mind and body working, and if you don't keep them busy, they'll not be happy campers.

An ideal situation for a Border collie would be a farm with sheep. Close second would be an active partnership with someone who's seriously involved in the sports of canine agility or obedience, where these bright, driven dogs really shine. I do know of people who keep BCs in suburban homes and even urban apartments, but those who do so successfully dedicate a lot of time and effort to meeting the needs of their dogs.

If you are not prepared to train and work your Border collie daily -- yes, daily! -- for an hour or so, then you're really better off with a breed or mix better suited to a less active lifestyle.

Q: We have purchased one of those cat feeders that allows you to fill it with a lot of food. Does this type of feeder promote overeating in our cat? She has put on a couple of pounds since we adopted her from the SPCA. -- T.W., via e-mail

A: I don't recommend free-feeding for most pets, not only because of the propensity of some pets to overeat, but also because free-feeding deprives pet-lovers of the ability to spot changes in eating patterns that can be indicative of health problems. My recommendation would be to feed your cat a measured amount twice a day.

That said, I'm also a firm believer in "if it ain't broke, don't fix it." The weight gain you report may well be fine for your cat, considering that she might have been on the thin side before you got her. If she has a little padding over her ribs, but not a lot, she's fine. If you're not sure, consult your veterinarian. A healthy, normal cat should weigh between 8 and 10 pounds (although some breeds are considerably larger or smaller).

If you and your veterinarian agree your cat is maintaining a proper weight and if you remain alert to changes in her health, then free-feeding may be an acceptable option.

For parrot lovers, there's not much worse than having a pet who plucks out his own feathers. After all, their beautiful plumage is one of the reasons we love having birds around. It's hard to appreciate the appearance of a bird who looks more like a plucked chicken than a lushly and colorfully feathered parrot.

It's harder still to cope when you find out that feather-picking can be very difficult -- if not impossible -- to change.

Feather-picking isn't a disease, but rather a symptom of something else that's gone wrong. The only hope of "curing" feather-picking is finding out and treating what's behind the behavior. And that can be difficult, since any number of underlying problems can be triggering a bird's need to destroy his own plumage. Here are some of the most common:

-- Health problems. Medical conditions behind feather-picking include allergies, parasitic infections, bacterial infections, abnormal growths such as cysts in the feather follicle, internal health problems, vitamin deficiencies and hormone-associated problems. And that's the short list!

-- Low humidity. Many pet bird species come from extremely humid environments, and our houses surely can't duplicate the conditions of a rain forest. The dry air of most homes can be a factor in feather-picking.

-- Boredom and pent-up energy. Parrots are active and intelligent, and they don't deal well with the strain of being forced to sit around in a cage all day. Without things to play with and stuff to destroy, and without being able to get out of the cage and exercise, birds may direct all their energy toward self-mutilation.

-- Psychological problems. Although parrots need to have their flight feathers trimmed for safety, a bad wing trim (too short, with no allowance for an "easy landing") can upset a bird so badly that he starts tearing at himself. Obsessive-compulsive disorders can also trigger feather-picking.

-- Attention-seeking. You love how your bird looks. He starts tugging at feathers and you freak, imagining your beautiful bird with the look of a broiler chicken. Every time he touches his feathers -- even for normal preening behavior -- you rush over. See how this works? "Aha!" thinks your bird. "All I have to do to get attention is pull a feather!"

What can be done with the feather-picker? First, forget the over-the-counter and home remedy "cures." They don't work, and some might even put your bird at risk. See a veterinarian with experience in caring for birds as soon as the problem appears. Medical problems need to be addressed before looking at any behavioral strategies. You should make sooner, rather than later, your emphasis. In general, the longer your bird has been picking, the greater the probability of an unresolvable pattern of behavior being set.

After your bird receives a clean bill of physical health, follow your veterinarian's advice and start making environmental adjustments. Prepare for the project to be a long one! Start a diary to record your changes and any effects they may have on your bird's behavior.

Start shaking things up, in small increments. A daily misting with a spray bottle and the addition of a room humidifier may be part of the solution. Also consider different toys, a smaller or larger cage, a new cage location, keeping a radio playing during the day, covering the cage to ensure your bird 12 solid hours of sleep, and more interaction and play with you as possibilities in the war against feather-picking.

In some cases, feather-picking is for life. In others, the problem is only occasional. Yes, some birds do become full-feathered again, but not every problem parrot is bound for complete recovery in the plumage department.

Sometimes the best you can do is be determined to love your bird no matter what he looks like. And that's only fair, considering that he'd do the same for you.

THE SCOOP

If a rabies shot isn't required by law for your cat, should you ask your veterinarian for one? If your cat ever goes outside, the answer is yes.

Even in urban areas, outdoor cats are at risk of being bitten by rabid wild animals, such as skunks, foxes, raccoons or bats. Rabies is so dangerous that, if he were to contract it, your cat would need to be euthanized, and you would need to have a series of inoculations for your own protection.

Rabies is nothing to take a chance on. If your cat goes outside, talk to your veterinarian about protecting your pet and your family with a vaccination against this deadly disease.

QUESTIONS FROM THE PACK

Q: We have a 4-month-old Lab-mix puppy and an 11-year-old cat who aren't getting along after nearly six weeks. We understand the cat is a little overwhelmed by the large bouncing animal who wants to play, but even when the puppy is quiet she growls and swats at him. Do we try to force them together or just hope it works out in time? -- R.H., via e-mail

A: Do not, under any circumstances, force your pets together.

Instead, make sure your cat is able to get away from the puppy whenever she needs to. A good way to accomplish this is to set up a baby gate across the entry to a bedroom where she likes to sleep. Her food and water should also be in an area the puppy can't get to, perhaps on top of the washer or dryer, or other elevated spot. And certainly make sure she can use her litter box in peace -- no one likes to be disturbed in the bathroom!

If you allow her to feel safe in areas where the puppy can't reach her, she should settle down, especially as the puppy matures. Realize, though, that there's a chance she may never warm up to this interloper. Sometimes the best you can hope for when older cats are introduced to new pets is an armed truce.

Q: Our male, neutered Jack Russell terrier turned a year old yesterday and continues to be very aggressive toward children and strangers.

I'm sure this is pretty normal for this breed, but my wife was hoping to have a pet who could be taken to Little League games, etc., and would be more docile around others. He's great with us, but he usually growls, lunges and barks at those with whom he's not comfortable.

I have heard of a puppy boot camp in Wisconsin. Do you know about it, would it be good for him, or should we just send him back to his breeder? -- J.W., via e-mail

A: Aggression is not normal for any breed, although some dogs do show a greater tendency toward developing it if the owners don't catch the signs early.

The aggression is a real concern, and I don't mean to downplay it. But don't be in such a hurry to pack off your pup, either to boot camp or back to the breeder. You need professional help to evaluate your dog: how aggressive he is (as in, does he act tough, or is he actually prepared to bite?), what you have done unwittingly to reward the behavior, and what you can do to extinguish it.

Contact your closest school or college of veterinary medicine and get an appointment with a veterinary behaviorist. (If you live in a large urban area, there might be one in private practice as well. Ask your veterinarian for a referral.) A veterinarian specializing in behavior can evaluate your dog and can prescribe medication that will help with the behavior either permanently or transitionally. He or she will also set out a program for you to follow to work on changing the problem. If, in the behaviorist's opinion, the dog is dangerous and has no reasonable chance of being made safe, you'll be able to work with this specialist to figure out your "what next?"

A Jack Russell will never be a laid-back dog -- and the people who fancy the breed love their energy and spark. But by working with a veterinary behaviorist, you may be able to turn him into a dog who'll happily and safely enjoy Little League games with your family.
