DEAR READERS: Various concerned individuals and organizations are pushing for legislative solutions to reduce horse-racing injuries.

In 2019, 38 horses died at the Santa Anita Park racetrack in California. Additional thousands nationwide suffer injuries that do not immediately kill them, but tear tendons and crack bones so they cannot be raced. So they go on long journeys to slaughter for the horseflesh trade in Canada, Europe and Asia.

Legislation to monitor and prohibit drugging horses to boost performance and mask prior injuries, and prohibiting their slaughter for human consumption, is in the works, according to the blog “The Political Animal” by Wayne Pacelle (animalwellnessaction.org).

All of this sounds great, but my opinion as a longtime monitor of this corrupt industry is that banning horse slaughter for human consumption will just mean more horse meat being recycled into pet food. And even worse, no one is standing up and saying these thoroughbred horses should not be raced until they are more mature: They need time to allow their skeletal structures to mature and better bear the strains and stresses of high-speed racing. In my mind, this is the most important issue -- and of course, it is unacceptable to the industry because of costs. Instead, the horses must earn their keep at an immature age by racing, a risk which I consider unethical. I believe it warrants outlawing this entire industry until it adopts the logical and humane standard of no competitive racing until these beautiful animals are more mature: between 3 1/2 and 4 years of age.

DEAR DR. FOX: I have a 4-year-old rescue Chihuahua that habitually chews her nails. I have tried applying Bitter Apple, but it’s only a short-term deterrent.

When we first visited Gabby in our vet’s office, I noticed her nails were very long and that many had been chewed. We assumed the chewing was due to the stress of being surrendered to a shelter, then having been in a foster home for two months with several dogs.

When we agreed to adopt Gabby, we contracted for a complete exam including lab work, microchipping, dental X-rays, teeth cleaning/any necessary extractions, and nail trimming. We brought her home and I established a routine of trimming/filing her nails usually weekly, hoping to get the overgrown quick to retreat and break her of the chewing habit.

I trimmed her nails earlier this week, but noticed today that she has chewed several down to the quick. She was left alone for only two hours this week, but I have also caught her chewing when we are together. When I say “No chewing,” she puts her perky ears down and ducks her head, so she knows better. She is now a spoiled, totally indoor lap baby: She quickly learned to use potty pads, she sleeps with us and is so bonded to us that we should change her name to “Velcro.” When we do leave her, she is behind a pet gate in our laundry room with a potty pad and her fleece-lined cave bed. She gets in her bed, lets me cover her up and shows no sign of being stressed, so I do not think the nail-chewing is due to separation anxiety.

I have been an obsessive pet mom for 57 years. Our vet of 45 years referred patients to me for Maltese grooming advice and for training dogs to use indoor potty pads, so I am not inexperienced in pet care. Gabby’s nail-chewing habit has me stumped. Any suggestions you have will be greatly appreciated. -- M.H., Tulsa, Oklahoma

DEAR M.H.: Nail-biting and chewing (onychophagia) is generally an anxiety-triggered and anxiety-relieving behavior seen in humans, dogs and other animals.

I put this kind of behavior -- along with excessive grooming and fur-pulling in cats and feather-pulling in birds -- in the stress-related, obsessive-compulsive category. These habits have a life of their own once they become established, self-reinforcing cycles. Such bad habits can lead to secondary bacterial and fungal skin infections between the toes in many dogs.

Soaking Gabby’s paws in apple cider vinegar for a few minutes, then drying them off, would be Step 1. No more nail trimming for a while. Then get outdoors for physical activity, and indoors, engage with squeaky chew-toys and any activity that helps redirect your dog’s attention. Wrapping the dog in a light towel so she cannot reach her paws so easily while you are together on the sofa might help both of you relax.

The best step to take, which you can discuss with your veterinarian, is to attempt to break this conditioned anxiety disorder with a short course of treatment with Prozac to elevate feel-good brain serotonin. I would combine this with twice-daily massage therapy, as per my book “The Healing Touch for Dogs.” If the Prozac does not work, then I would try CBD, but not all veterinarians are prescribing cannabinoids for their animal patients. I strongly advise against purchasing such products in states where the sale is legal to give to companion animals without veterinary supervision.

DEAR DR. FOX: I enjoy reading your column, and saw the recent question from N.V. regarding deceased pets.

My beautiful Kokonut, a mini schnauzer, crossed the rainbow bridge on July 19.

She was 12 1/2 years old at her passing, and fought a brave battle against melanoma for almost one year.

She gave me “the look,” and I knew it was her time. Her fairly new vet, Dr. Block, helped her cross over peacefully at home with a candle, mala (prayer beads), feather and prayers. I miss her every second of every day. She was my first dog and we were very connected.

Almost immediately after her passing, I would awake to a soft “woof” during the night. I was not dreaming, and it was definitely her bark. During the day, I would hear her sigh, something she did before taking naps.

The week after she crossed, I was going to run some errands. I made my bed as usual, pulled tight. When I returned a few hours later, her indentation was on the comforter. Almost one week after that, I felt her jump on the bed and snuggle in the crook of my legs, something she had not done since she was a pup.

These visits brought me great comfort and helped me begin to heal. On Aug. 22, Kokonut sent a new fur baby to me: Karma. He is a mini schnauzer rescue, approximately 2 years old. Kokonut has not made a visit since he arrived, but I know her spirit is within him.

While losing her was one of the most heartbreaking experiences in my 60 years, she left me a better-educated owner. Karma is on a fresh/raw diet, healthy and full of life. I take an integrative approach with his care. -- J.P., Boca Raton, Florida

DEAR J.P.: Your account of after-life manifestations of your beloved dog accord with many identical accounts posted on my website (drfoxonehealth.com). See my review: “Animal Spirits: Companion Animal Communications From Across the Grave,” posted under the tag “Spiritual Issues.”

I address this question of life-after-life from various perspectives as a scientist, philosopher (phenomenologist) and rational skeptic. The hypothesis that such experiences come from our grieving, conditioned brains, i.e. hallucinations, is null and void when these many accounts and shared existential experiences are examined. They support my theory that the bond of affection between humans and other species can transcend time and space, and endure after death. Such generally comforting “visitations” often stop when the survivor ceases to mourn and, as in your case, bonds with another animal.

For some, this raises the question of reincarnation or a “group soul” -- an esoteric realm which I neither accept nor reject. I prefer to focus on existential reality and the quality of life we can best provide for domesticated animals, and those in the wild who continue to suffer because of a cultural lack of reverence and respect for all life.

I am glad that your new canine companion was a “rescue,” and wish more people would adopt rather than support puppy mill commercial breeders.

DEAR DR. FOX: I appreciated your recent column on cat’s predation on wild birds.

I have a neighbor who harbors maybe 10 cats in a housing plan whose rules on numbers of cats is not enforced; thus, I am on the front lines of combating not so much the cats, but my neighbor’s ”cat neurosis.”

Perhaps you could address the core problem: some humans’ mismanagement of their relationships with cats, which is not environmentally sustainable or considerate of those who live near them. -- S.R.P., Uniontown, Pennsylvania

DEAR S.R.P.: Many people in communities across the U.S. are confronting the kind of neighbor you are dealing with.

Such neighbors are emotionally dedicated, but their compassion is misguided and can cause more harm than good when the cats are not neutered and continue to multiply. And even well-fed cats will kill birds and small mammals. Feral cats in many areas are decimating defenseless wildlife species, many now endangered. Recent documentation in Australia indicates that some 100,000 need to be exterminated as humanely as possible.

On my website, you will find some articles addressing this problem in the U.S:

-- “Most Feral Cats Can be Rescued and Recover from the Wild Outdoors”

-- “Outdoor Cats, Wildlife and Human Health”

-- “Releasing Cats To Live Outdoors: Humane, Environmental and ‘One Health’ Concerns”

Do look these over, and feel free to share them with local property owners, community leaders and public health authorities. Get support from any local conservation organization, such as the Audubon Society and the national American Bird Conservancy, who also have useful materials to encourage people to keep their cats happy and healthy indoors.

DEAR DR. FOX: I have a question about our dog. We are stumped.

He is a healthy 5-year-old neutered male. He has had his teeth cleaned, and has routine vet appointments. He has no smell on him per se, but his dog bed has to be routinely washed because of a rather nasty smell. It is a sweet but “rotting” smell, and he leaves brown stains where he licks. The licking is mostly in a normal grooming manner. His breath is terrible, but it’s not the same smell.

Do you have any ideas? The smell gets so strong you can smell it throughout the room, sometimes until the bed is washed. We are currently feeding him Purina Pro Plan Focus Lamb or Chicken and rice. Is there a better dog food we should feed him? His breath is fishy and foul, but his bedding is just gross. -- D.H., Kalispell, Montana

DEAR D.H.: Healthy dogs do not have a bad smell.

Many people with stinky dogs repeatedly bathe them under the erroneous belief that will help. This can often disrupt the healthy microbiome on the skin and lead to secondary dermatological problems.

Feeding dogs a diet of only dry kibble is ill-advised, regardless of what some veterinarians and advertisements might proclaim. For details, read my article “Dog Food and Feeding Issues” on my website (drfoxonehealth.com). Also consider making your own dog food, as per my posted recipe.

Some of the ingredients in what you are currently feeding your dog, such as “animal digest,” I would never give to a dog. For verification, check out the book “Not Fit for a Dog: The Truth About Manufactured Cat and Dog Food,” which I co-authored with two other veterinarians. Your dog’s “fishy and foul” breath is from the fish in this manufactured material. Such kibble, with all the cereal glutens in it, tends to linger between the teeth like glue.

At the very least, feed your dog some good-quality canned dog food or freeze-dried food with some grains, such as The Honest Kitchen’s line of dog foods. And be prepared to spend more, since good nutrition is the best medicine for us and our animal companions alike.

DEAR DR. FOX: In one of your recent columns, a reader had a dog with a barking problem.

I have successfully stopped my fur baby’s barking by using either a squirt bottle of plain water or a pop can/plastic bottle filled with a few pennies. The squirt of water or the rattling noise seems to distract the culprit, and helps them learn to stop the habitual barking.

I would never use chemicals, and I consider shock collars inhumane and would like to see them banned.

We recently adopted a 3-year-old female rescue Chihuahua, who knows that one bark at the sound of the doorbell is all that is necessary. -- M.H., Tulsa, Oklahoma

DEAR M.H.: Many thanks for the reminder for all dog owners about how quickly and easily dogs will learn to stop barking using the simple aversion conditioning of a sudden noise or squirt of water. Throwing a bunch of keys toward them also works well. But it is best to first give the warning signal of a verbal command, such as “No! Quiet” before shaking the can of coins or pebbles, or using a spray bottle. This is called conditioning, and eventually you only have to give the verbal command and can abandon the aversive stimulus.

I was in shock the other day, when purchasing birdseed at the local hardware store, to see a whole shelf of electronic devices to go on dogs’ necks and deliver shocks to stop barking. It seems we are on the threshold of turning our dogs, as well as our children, into virtual zombies with all these electronic devices in our homes.

Stopping a dog from barking when you are not there to control the dog is a common problem and, as I stress in my book “Dog Body, Dog Mind: Exploring Your Dog’s Consciousness and Total Well-Being,” snipping dogs’ vocal cords is an ethically unacceptable veterinary service when other measures are not taken.
