DEAR DR. FOX: My sister adopted a female German shepherd, Cassidy, from a rescue organization about two years ago, at which time the vet believed she was a little more than 4 years old.

Monday through Thursday, Cassidy is in contact with her owner and her regular dog walker (me). On the weekends, Friday afternoon through Sunday evening, she is cared for by two other family members at a different location, approximately 25 minutes away by car.

Is it harmful for Cassidy, either emotionally or physically, to be shuttled back and forth between her owner and the other family members? Is it confusing or upsetting for her to maintain this schedule on a weekly basis? All parties involved would like to continue with the current arrangement, but only if it is not detrimental to Cassidy in any way. -- S.M.P., Gaithersburg, Md.

DEAR S.M.P.: I appreciate your concern. Most dogs would enjoy this kind of extended pack and two-den lifestyle, since it provides more varied stimulation and environmental enrichment, rather than seeing the same people and places day in and day out.

I am happy to see dog owners linking up on the Internet and community bulletin boards for dog play groups. It's even good for a person with a dog to take in others while their owners are away at work -- yes, a doggie day care business.

Boredom, loneliness and separation anxiety are modern dog burdens. Having more than one dog and a dog walker to get your pet outside for stimulation and physical activity during the workweek are responsible decisions. A happy dog is a healthy dog.

DEAR DR. FOX: How often should a dog be bathed? My sister insists that her Chihuahua needs to be bathed every week or so, and I say it dries out his coat and he doesn't need it. What is your opinion? -- P.O., Cumberland, Md.

DEAR P.O.: There are no set rules beyond those of common sense. You could be right about drying out the dog's coat. Too-frequent shampooing can also encourage skin infections when the protective oils and healthy skin bacteria are washed away. Some dogs never need bathing, just a daily brushing. Older dogs often need to be bathed as soon as they get stinky -- for their own comfort and for those living with them. This may be every two weeks or so, especially for those with naturally oily skin. There are spritzes and dry shampoos on the market that can help deodorize dogs' coats, like Bath Eaze from PetzLife. You can try to make up your own spray using an emulsion of 100 parts water, 100 parts aloe vera liquid or coconut milk and 1 part lavender essential oil.

I would advise bathing any dog who has been swimming in the ocean, where salt residues can be irritating to the skin, or in a lake or pond, where harmful bacteria, algae and parasites can flourish during warm summer months. Remember: Do not let your pet quench his thirst from these potentially harmful natural sources. Some kinds of blue-green algae can kill dogs within hours, and fecal (human and animal) contaminants such as cryptosporidium, salmonella, shigella, E. coli and norovirus can put all bathers at risk, especially those with compromised immune systems.

49 PEOPLE SICKENED BY CONTAMINATED PET FOOD

Salmonella-contaminated dry dog food from Diamond Pet Food Processors' plant in Gaston, S.C., sickened 47 people in the U.S. and two in Canada, the Centers for Disease Control reported. This figure is probably low because victims may have become mildly ill or attributed their condition to food poisoning that doctors and other health authorities failed to connect with this contaminated pet food. People can become ill by direct exposure to the food or by contact with animals who consumed it. No fatalities were reported.

DEAR DR. FOX: I am writing to you in response to your request for communications from the grave.

My 16 1/2-year-old Aussie, Megan Rose, died Sept. 5, 2010. I took her death very hard.

When I got her ashes, I put them on my bureau. I have a wall vase with four blue roses that hangs next to the bureau. A few days later, I found a rose on the floor. I thought it was strange because no roses had ever fallen out before, and I had never touched them. I put it back in the vase.

The same thing happened the next day. And on the third day it happened again, only this time when I found the rose I said, "Megan Rose, is that you?" I put the rose back in the vase, left the room and came back a few minutes later only to find the rose on the floor again. I thought to myself, What a perfect symbol -- her name is Megan Rose, and here is a rose. Nothing happened again for six months.

On her birthday in March 2011, when I got up in the morning, I went to the bureau, picked up her ashes and said, "I wish you were here for your 17th birthday" and gave the box of ashes a kiss. As I was putting the ashes back on the bureau, lying next to where her ashes had been was a blue rose. -- J.H., Seymour, Conn.

DEAR DR. FOX: Thanks for writing about "ghost" animals in your column. It was a comforting and nonjudgmental response to your reader. I know many of us who have lost pets will find comfort in your words.

When we moved into our house 20 years ago, my husband and I felt the familiar landing of a cat at the end of our bed and the slow movement of paws up to our pillows. No cat was there. We called it "ghost kitty."

We would reach out to pet the cat or talk to it, but we just touched air. Our live cats (we had several) would not stay or sleep in our bedroom, so it wasn't a case of mistaken identity. This routine continued for many years until we adopted three homeless cats who took up residence in our bedroom (by choice) and never went downstairs until many years later. We hope "ghost kitty" has gone on, but, from time to time, we still wonder about the cat. Your column has given us an insight into this phenomenon. -- L.R.R., Virginia Beach, Va.

DEAR J.H. and L.R.R.: Many readers will appreciate your letters. Several communications from our beloved departed pets are posted on my website, DrFoxVet.com; these stories support my belief that such phenomena are not mere coincidences or products of the imagination.

It is my contention that the more mindful we are of the spiritual dimension of existence and the great mystery of conscious life, the more we may begin to improve as a species in our regard for and treatment of all creatures great and small.

DEAR DR. FOX: When my husband and I had our first dog, a beagle/boxer mix, we were amused and annoyed that when we let her out, she would always head for a patch of garlic that my husband planted for fun. That was her favorite resting spot. We couldn't figure out why she picked such a smelly place, but it finally dawned on us -- no fleas!

We have had several dogs through the years and always included garlic (fresh or powdered) and brewer's yeast in their food, and we have never had a sign of fleas or ticks.

Dumb dogs? I don't think so. -- R.K., St. Louis

DEAR R.K.: Your first dog certainly demonstrated a degree of "wild wisdom" in her choice of lying on a patch of garlic growing on your property.

British biologist Dr. Cindy Engel compiles many fascinating accounts of animal species self-medicating with various herbs and treating wounds and even broken bones in her book, "Wild Health: Lessons in Natural Wellness From the Animal Kingdom" (Houghton-Mifflin).

Freshly chopped garlic and its potent oil extract have many medical benefits. However, it is an irritant to the stomach lining, so it is best taken with food. It can act as a natural antibiotic, anti-viral and anti-fungal agent. It can rid the body of intestinal worms. On the skin, garlic can help heal burns and kill ringworm. It may help diabetics lower their daily insulin dose. Garlic can be helpful with many other conditions, including toothache, heart problems, high cholesterol levels and allergies. It is a potent blood thinner, helping prevent coagulation and clot formation. It may also help lower blood pressure.

These are just a few of the medical benefits of this remarkable herb. It can cause a form of anemia in cats, but is safe for most dogs. You can give one large clove per 30 pounds of body weight with food. Coupled with 1 teaspoon per 30 pounds of body weight of brewer's yeast, it works well to keep fleas and other biting insects away from dogs and people alike.

DEAR DR. FOX: I read your article on feral cats, and I thought you might like to hear the story of mine.

About 26 years ago, I saw a small stray cat going across the street and down the sewer. I started feeding him. About 8 months later, on a cold, bitter, snowy day, I was able to catch him. My wife and I put him in our basement and didn't see him for a week. Then one day, he came out and became the talk of Old Orchard in Webster Groves, Mo. He was about a year old, and we named him T.C. -- short for The Cat.

He lived in my barbershop until I retired in 2007. He would sit on the step outside with the door wide open and greet anyone who came along. He was so popular, one of my customers, John Marecek, wrote a poem about him, and it was published!

He lived a good, long life in the comfort of the barbershop for 25 years. He passed away in January 2011. -- G.B., St. Louis

DEAR G.B.: Thanks for your heartwarming story many readers will enjoy. It is noteworthy that T.C. had no interest in leaving your shop even though the door was wide open. Similarly, Mr. Mark Twain, our old, formerly feral cat has never shown any interest in going back outside once he decided to come out of hiding in our home. He felt it was safe, trusted us and knew we were his food, water and clean litter box providers.

As you discovered, having a cat can be good for business, putting clients at ease and providing a catalyst (pun intended) for conversation. Dogs can be great, too. Unfortunately, there are many city ordinances that prohibit having an animal in a business, though this is not true in more animal-civilized countries like England and Holland.

I'm including my two favorite lines from the poem about T.C. by your customer John Marecek:

Men enter the shop and seek out his bed

To just say, "How are you?" and then pet his head.

DEAR DR. FOX: We have two dogs, a 6-year-old un-neutered English bulldog and a 4-year-old female Chihuahua. They are indoor dogs, but they do go outside for exercise and bathroom duties.

When the Chihuahua urinates, the bulldog will come by and lick it, causing his tongue to freeze in place for a few minutes, then he drools. Why does he keep doing this? We have tried everything to stop him.

Is there anything you can think of that would help put an end to this disgusting habit? They both get along famously and are the best of friends -- they even sleep together. -- E.W., West Falls, N.Y.

DEAR E.W.: What may seem disgusting to you is perfectly normal canine behavior. Some people are even put off when dogs sniff each other's rear ends.

I can understand anyone protesting when his dog rolls in some stinky, organic goop, but that is, in some ways, akin to humans putting on perfume.

Your English bulldog is showing the Flehmen reaction, which is most often seen in bulls and stallions sniffing the females of their species. In a Flehmen reaction, the tongue curling and freezing is done to place the scent or pheromone of whatever has been licked on a spot just behind the upper front teeth. This is where two ducts leading to the vomeronasal organ are located -- a second scent organ present in other mammals, including cats, who often show the Flehmen reaction when sniffing and tasting various substances. This organ may play an important role in pheromone influences on the animals' brains and behavior.

So please accept your bulldog's bond-affirming behavior, and let him be.
