DEAR DR. FOX: I just lost my dear cat to cancer that started at the site of his last rabies injection.

I have had several friends who also have had cats who developed that kind of cancer, I believe called fibrosarcoma, at the rabies injection site. Veterinarians have always told me that the risks from the injection are very low, but now I don't believe them. I am incensed that an indoor cat is, by law I am told, expected to have an injection for a disease that he would have no way of catching.

What is your take on this? -- M.H., Bethesda, Maryland

DEAR M.H.: I am sorry to hear about the death of your cat due to fibrosarcoma at the injection site. I have discussed this and other adverse vaccination reactions, so called vaccinoses, in an article on my website, DrFoxVet.net.

I think the protocol of annual rabies and other vaccination to indoor cats needs revision; it is questionable to vaccinate against rabies in cats who never go outdoors and have no possibility of exposure to a rabid animal unless one gets into the house. But if you need to board your cat, all such vaccinations should be up to date and you should get blood tests confirming that the cat does not have feline leukemia or immunodeficiency virus infections.

Regrettably, we have uninformed and uncaring members of the cat-owning community who let their unvaccinated cats go outdoors whenever they like. There are not enough communities with statutes and ordinances prohibiting cats from being allowed to roam off their property, and the enforcement is a joke. All cats who are outdoors in an enclosed yard and who do not wander off their owner's property but could be exposed to rabid animals and to diseased cats do, of course, need to be vaccinated.

In my opinion, judging by the number of letters I receive concerning cats developing injection-site cancer, the incidence is higher than the estimates reported in the literature, and not all veterinarians are following the new protocol of no longer injecting the rabies vaccine in the neck or shoulder area but down one limb or tail. When the anti-rabies vaccine is injected at these sites, it makes surgery to remove any tumor -- usually total amputation -- more effective in preventing its spread.

DEAR DR. FOX: One of our standard poodles often throws up a small amount of yellow substance when it is close to mealtime. We are very punctual about meals and try to compensate, but it doesn't work. Can you help? -- M.F., Springfield, Missouri

DEAR M.F.: This is probably bile and gastric juices triggered by the anticipation of food and aggravated by acid reflux, so try giving your dog a human Tums (or similar antacid) 20 minutes before mealtime.

A surprising number of dogs have this problem, but I do not advise people making their own diagnosis since such vomiting before and after meals can mean other serious health issues. So if the antacid does not prove effective, a full veterinary checkup is called for.

DEAR DR. FOX: Do you have any suggested changes in your home-prepared dog food recipe for geriatric arthritic dogs? -- S.M., Washington, D.C.

DEAR S.M.: I have recently made a few general changes to my home-prepared dog food recipe, posted on my website.

I have included natural herbal supplements that help dogs in general and older dogs in particular. Ginger and turmeric are two examples of such herbs that have a diversity of beneficial pharmaceutical and therapeutic properties.

I would add a little cinnamon for dogs with diabetes and high blood pressure (often associated with kidney disease). Try oregano, thyme, sage, cumin or fenugreek for those with digestive issues. I would give a pinch in the food for habituation and acceptance, then increase to about 1/2 teaspoon daily of each for a 50-pound dog. Many people are surprised how many good medicines they have in their own kitchens; traditional wisdom -- like Hippocrates urging, "let food be thy medicine and medicine be thy food" -- is anathema and taboo to the pharmaceutical industry.

In addition to such supplements to help old dogs, I would add massage therapy that you can give yourself. Learn more in my book "The Healing Touch for Dogs."

DEAR DR. FOX: I am writing to see if you might have any answers as to what could be causing my dog to have red, irritated skin around his muzzle. His hair is patchy around his muzzle, and it seems to be itchy and bothersome to him. He constantly scratches and rubs his nose on the carpet to itch it. We mentioned this to his vet, who did a skin scraping; the test came back negative. The vet also did a fungal test, and the results were negative. He put our dog on an antibiotic in case it was a bacterial infection, and he also prescribed prednisone in case it was fungal.

The medications did not help to clear up the irritation. The vet suggested changing my dog's food bowls to stainless steel because some dogs have allergies to plastic food bowls. We would have, but our dog has always had stainless steel bowls. The vet recommended trying different dog foods because some dogs are allergic to a carbohydrate or a protein in their dog food, so we tried a couple of different dog foods over the course of several months. So far, none of these changes has made a difference.

There hasn't been anything else that we use differently or anything different that we give our dog that we can think of that could be causing this irritation. However, we did move into a new house relatively recently. It has been almost a year since he started having this irritation around his muzzle, and it doesn't seem to have gotten any better, although he doesn't seem to scratch at it as much.

The last time we took him to the vet, he didn't have any other suggestions except to try another skin scraping. We did not proceed with another skin scraping as our dog would not cooperate, and the vet would have to put him under anesthesia to be able to get the scraping. We didn't feel it would be good to put him under anesthesia, so nothing has gotten resolved.

Do you have any advice or ideas as to what could be causing the irritation or any remedies that we could try? -- E.L., Moorhead, Minnesota

DEAR E.L.: That the vet said he would have to anesthetize your dog to take a skin scraping is absurd and risky, but profit-making indeed.

I would advise you to seek a second opinion. Explore a possible autoimmune disease like lupus or mange, and avoid all further topical and oral anti-flea drugs. Avoid using floor and surface antibacterial cleaners containing quaternary ammonium compounds and volatile synthetic room "fresheners."

I wonder about the carpets in your new home. Have them checked for allergens. Chemicals in fitted carpets could be at the root of your dog's problem, so put down cotton sheets where he sleeps if you do not wish to remove them.

DEAR DR. FOX: We adopted a dog about a year ago. As he was a shelter rescue, we don't know much about him, but he seems to be a mix of Chihuahua and Pomeranian, and about 6 years old.

At first we had no trouble with him aside from the occasional accident in the living room, but lately he's started biting hard enough to draw blood. We don't know what provokes him. I'll be petting him when suddenly he snaps at me. He also snaps sometimes when I try to put on his leash.

Can you offer any thoughts on what's going on? We'd hate to give him up. -- F.S., Brookfield, Connecticut

DEAR F.S.: Any change in an animal's behavior, as you are experiencing, calls for a veterinary checkup to rule out a physical cause, such as a painful ear infection or neck injury.

After that, you can move ahead with considering psychological reasons, especially overindulgence, allowing the dog to have his own way, not being consistent in rewarding good behavior and inhibiting and redirecting bad behavior. This is where the veterinarian can give you a referral to a certified animal behavior therapist or experienced dog trainer so you can enjoy your dog's company and not have to think about giving him up.

DEAR DR. FOX: When my son's Yorkiepoo joined my household, she seemed to have thought she hit the jackpot. She was more interested in eating waste from our house bunnies than her own food -- to the point where she would hide in their cage. Our (now-deceased) cocker spaniel, who had never done anything like that her whole life, seemed to think that if the puppy could do it, she could, too.

The major dog food brand I'd been feeding them had multiple shapes. One looked just like rabbit droppings. Once I began feeding the dogs food prepared using your recipe, they stopped eating the rabbit waste.

I suggest people whose dogs like eating animal waste switch to your recipe and see if it makes a difference. -- R.S.B., North Beach, Florida

DEAR R.S.B.: Thanks for your confirmation of the benefits of good nutrition for dogs. Many people have written to me about the improved health and behavior of their dogs and cats after being given home-prepared food from my recipe or making a similar change in diet from highly processed "junk" pet foods.

Nestle's Purina is promoting probiotics in its foods, which can help dogs with digestive issues and poop-eating; the company has added "animal digest" as a flavor enhancer, which I would recommend readers investigate at truthaboutpetfood.com.

I have slightly revised my dog food recipe with some additional beneficial herbal supplements, now posted on my website, DrFoxVet.net.

DEAR DR. FOX: I've read many of your columns about stray and feral cats, and I agree that it is a serious problem in our country. But it seems you present the problem most often without offering a solution.

Spaying and neutering is the primary answer to this issue, but many, if not most, in your profession stand in the way of progress in the name of making a buck. When you take a cat in to spay or neuter, the latter of which is a so-easy-it's-crazy procedure, and leave with a bill of $200, $300 or more, you are encouraging people to do the wrong thing. Because how could they afford to do the right thing?

I would love to see a column with a more concrete plan of action than just "don't feed them." That isn't, and won't ever, end this "plague." -- J.S., Middletown, Ohio

DEAR J.S.: I appreciate your concerns. I encourage people to have their cats neutered, adopt neutered cats, keep their cats indoors and not feed stray cats unless there is the intent to capture them and have them neutered and vaccinated and rehabilitated for adoption.

Teams of veterinarians across the country offer their services at low cost to spay and neuter cats in an effort to help reduce the "cat plague." Such efforts can make a difference, but they are costly, not quick-and-easy and involve general anesthesia and blood tests. Additionally, there must be owner education and local animal control ordinances put in place, which you can read about in my article "Releasing Cats to Live Outdoors," posted on my website.

We have yet another feral cat we trapped on our property in our home; after five weeks, he is becoming attached and playful and will soon be ready for a good home. He would have been killed in the average animal shelter or released back on our property soon after neutering under our local humane society trap-neuter-return community cat program so they can fly the no-kill flag. I say nuts to that -- a total abdication of responsibility.

PURINA DOG FOOD RECALL

Nestle Purina has announced it is voluntarily recalling select lots of its Beneful and Purina Pro Plan wet dog foods because they may not contain the recommended level of vitamins and minerals. The recall includes select lots of wet dog food under the Beneful Prepared Meals, Beneful Chopped Blends and Pro Plan Savory Meals brands.

Purina is conducting this voluntary recall as a precaution for those dogs who may have eaten the affected product as their only meal for more than several weeks. If you have questions about your pet's health, the company suggests that you contact your veterinarian.

Although most of the recalled product contains all of the vitamins and minerals your dog needs, Purina recommends that you discard any of the affected product you may have. For more information, visit newscenter.purina.com/10ozwetdogfoodtubrecall.
