DEAR DR. FOX: We have a mixed-breed pound dog who we adopted a couple of years ago. She's about 30 pounds and possibly a Sheltie. She's a good girl, and we truly love her. The weird thing is that she's an awful car traveler. She's fine at all other times, but I've never seen a dog behave like this.

She will eagerly jump into the car, but once it starts, it's a different story -- she cries constantly and hyperventilates. She will not sit still; we have to hold her the entire time. We have tried to get her accustomed to the car, but this seems to be a deep-seeded neurosis. We have tried kenneling her in the car and that doesn't help -- it seems worse than just holding her.

Is there anything we can give her to calm her down? -- H.L., Houston

DEAR H.L.: A study was recently published by an animal behaviorist in the U.K. that showed significant benefit from spraying the inside of the car with a mist of water mixed with a few drops of lavender oil prior to the ride. An occasional spritz on the dog may also help during a long journey.

Trying to desensitize your dog may be worth a try. This entails sitting in the car with the dog for increasing periods of time with the engine off, then the engine running, then going on longer and longer drives. The dog is given treats sporadically to associate being in the car with food rewards.

She may travel better and prefer the security of a dog crate or in a harness and tethered to a back seat. This is much safer anyway, and should be the law in every state.

Treatment with Valium (or its parent herb, valerian) 30 minutes before a ride may help. After a few treatments, many dogs settle down and can be weaned off the medication. For dogs who develop nausea and vomit, a small piece of ginger root in a ball of cream cheese can work wonders.

DEAR DR. FOX: I have a cat similar to one I read about in your column. She always had poop stuck on her butt, and it would rub off on the furniture. Her fur was greasy, smelly and matted. I had a groomer bathe and shave her once, and the grease in her fur clogged the groomer's shaver.

That was when she weighed 18 pounds. She couldn't reach to do much grooming other than her front paws and a bit of her sides. She's since lost weight, and from the time she hit about 14 pounds, she started grooming herself again, and now is a very clean, not-smelly cat. -- J.A.W., Wilbraham, Massachusetts

DEAR J.A.W.: I am glad you wrote about what may seem amusing but is in fact a serous cat welfare issue. It is a potentially criminal offense under the U.K.'s Animal Welfare Act to allow a cat or dog to become obese -- and for good reason. Animals' lives can become utterly miserable, not only from being too fat to groom and clean themselves, but they also become depressed, arthritic, develop diabetes, weakened hearts and other serious health problems. The fatter they become -- most often because of being fed the wrong foods and being given too many high-calorie treats -- the more their quality of life deteriorates.

DEAR DR. FOX: While visiting Houston, I adopted a Chihuahua mix, Paco, from a shelter. He was found wandering the streets, was close to starvation and had a severe case of heartworm.

When I brought him home to Massachusetts, he was a frightened, nervous dog. I worked with him diligently for a long time, but he suffered from colitis from the start. He was under the veterinarian's care from the beginning, and we could not get the colitis completely under control. I purchased a special Science Diet food from the doctor, along with pills and liquid medicine. Nothing worked well. He gained some weight, but seemed uncomfortable all the time.

One day, I came upon your column in our paper and read a letter from someone who had changed their dog's diet to your homemade food with good results. Immediately, I printed out your diet, went shopping and fed Paco the diet. It has been nine months now, and he has not had a single colitis episode.

My only problem is keeping the amount of food under control because he loves it so much. He hated the Science Diet, both dry and canned. He is now 16 pounds and looks great. He runs every day for over an hour (his energy is wonderful), he's happy and cheerful -- and I owe it all to you. Paco and I have made you famous among my dog-walking friends.

Everyone calls him "Paco the Wonder Dog" because he is so friendly and listens to every command cheerfully; I can tell it is because he feels so well. -- D.C., Northampton, Massachusetts

DEAR D.C.: I appreciate your letter confirming the benefits of home-prepared foods. I would like to hear from other readers whose dogs' and cats' health problems have been cured with my basic recipes. For more details, see my books "Dog Body, Dog Mind" and "Cat Body, Cat Mind."

More veterinarians are discovering that many chronic health problems are attributable to manufactured pet foods, and cannot be reliably rectified by special "prescription" and "premium" diets.

DEAR DR. FOX: We adopted a 5-year-old wire fox terrier six months ago. We don't have a lot of history on him except that he had at least two previous homes, was housed at the Humane Society at least once in between homes and was also foster-homed before coming to us. He is a real delight -- sweet, smart, playful and loads of fun. As long as he can see us or be with us, he is calm and under control. But when anyone (family, visitors or strangers) goes to leave the house or yard, he becomes extremely agitated -- barking, running wildly, snapping at the fence and grass and sometimes snapping at the person who is leaving. The same thing occurs when a motor vehicle comes in or leaves the driveway. The lawnmower, vacuum cleaner and other motor-related noises also seem to agitate him. Patient reassurance or humane corrections don't seem to help get him straightened away.

We would appreciate any advice, suggestions or tips that you can provide for this problem. -- M.W., Waldorf, Maryland

DEAR M.W.: Your dog has two conditions that call for different treatments.

His separation anxiety may wane over time and be, in part, attributable to his emotionally disruptive prior experiences. Leaving him briefly and repeatedly coming and going, gradually increasing time away (two, five, 10 minutes, etc.) is one behavior-modifying desensitization procedure that works for many dogs.

Becoming excited over loud noises like vacuum cleaners tends to go with the breed. You have to live with both.

Treatment with a low dose of Valium or Prozac for 10 to 14 days may help him learn to cope better with anxiety-triggering situations. You vet can also check out milder preparations include Tryptocalm LT from Meridian Animal Health and @-Eaze from PetzLife.

RACHAEL RAY NUTRISH WET CAT FOOD RECALL

Ainsworth Pet Nutrition of Meadville, Pennsylvania, is voluntarily recalling five varieties of Rachael Ray Nutrish wet cat food, including Ocean Fish-a-licious, Lip Smackin' Sardine & Mackerel, Ocean Fish & Chicken Catch-iatore, Tuna Purrfection and certain lot codes of Paw Lickin' Chicken & Liver, due to potentially elevated levels of vitamin D. Symptoms of excessive vitamin D consumption usually develop within 12 to 36 hours after ingestion and may include vomiting or diarrhea, increased thirst and urination, and muscle tremors or seizures. Any cat experiencing these symptoms should be taken to a veterinarian immediately.

The recalled products were distributed nationwide. No other Rachael Ray Nutrish products are affected by this recall.

To date, there have been 11 reports of illness associated with these products.

After conducting a number of product tests, Ainsworth confirmed that the affected products have elevated levels of vitamin D. The high levels result from the natural levels of vitamin D that are found in some of the fish ingredients that were used in these specific formulas.

Ainsworth is working to ensure the removal of all affected products from store shelves. Retailers with affected products are asked to contact 888-943-4218 for additional information.

Consumers with questions about the recall are encouraged to contact Ainsworth's Consumer Care Team at 877-650-3486, or visit nutrishforpets.com/news.

DEAR DR. FOX: In one of your columns, you mentioned that to control fleas, there are several safe alternatives to potentially lethal pesticides. Would you please elaborate? -- N.B.-R., Key West, Florida

DEAR N.B.-R.: There are no simple solutions for keeping fleas at bay. Several steps need to be taken that include treating animals' environments as well as the animals themselves.

The constant use of drugs on cats and dogs to prevent fleas in those states where there is a flea season (not year-round infestation, as in Florida) should be questioned. When it comes to using the new-generation anti-flea and anti-tick drugs, potential health risks and adverse environmental consequences call for caution.

A flea comb for daily checkups is a must. Also, thoroughly vacuum the floors, carpets and furniture every week. Giving brewer's yeast with your pet's food (about 1/2 teaspoon per 20 pounds of body weight) also helps repel fleas. Food-grade diatomaceous earth rubbed into the animals' coat will kill the fleas, as will FleaBuster's borate powder, which you sprinkle on carpets, sides of furniture and cracks in the floor. Visit PetzLife.com for some other effective anti-flea and anti-tick products.

Most importantly, electronic anti-flea collars are a scam!

DEAR DR. FOX: Please tell me how to stop submissive urination by my 1-year-old female Chihuahua.

I've read at least eight books on Chihuahuas and found no reference to this problem, with the exception of one short sentence saying they'll outgrow it. Well, this one didn't.

We bought this dog at 12 weeks. She was easy to train, and all was well for about a month, then she began to slightly urinate when anyone petted her. By then we had fallen in love with her and tried everything to stop this problem: We approached her quietly, after she had time to settle down, and even got down to her level. No change. We hoped she'd outgrow this, especially after she was mature and spayed at 11 months -- still no change.

She seems shy, and we can't figure this out. She came form a loving home-breeder to our calm and quiet adult-only home; she's never been scolded.

She is ruining our carpets and upsetting anyone who visits us. This is frustrating beyond belief. Please help. -- G.C., Pompano Beach, Florida

DEAR G.C.: It is true that most dogs outgrow urination as a display of submission. Those who don't are either extremely submissive by nature or have developed a conditioned fear reaction to their caretakers, who either punish them or rush to clean up and thus frighten the dog.

Try ignoring your dog every time she piddles, and encourage her to play with you -- the rougher the better (I especially recommend tug of war with a knotted rope). As she develops more self-confidence and you stay calm whenever she piddles, you may well see increasing continence. If this fails, discuss hormone-replacement medication with your veterinarian to help improve urine retention and sphincter control.

"ORGANIC" BUT NOT NECESSARILY HUMANE

Many people who consume animal products and feed them to their cats and dogs have been relying on the United States Department of Agriculture's "Certified Organic" label as an indicator of humane treatment of farmed animals.

When I was an adviser during the time that the National Organic Standards for farmed animals were being drafted, it was agreed that in order to qualify for USDA organic certification, operations producing milk, meat and eggs must allow the animals access to the outdoors.

Now corporate agribusiness interests across the country are operating industrial-scale confinement facilities, providing no legitimate grazing, or even access to the outdoors, as required by federal regulations. Video documentation by Wisconsin-based Cornucopia Institute (cornucopia.org/organic-factory-farm-investigation) exposes this atrocity that needs to be addressed by state and federal lawmakers and regulators.

Voice your concerns to your state and congressional lawmakers, and call for a full investigation.
