DEAR DR. FOX: My beloved Rosie, a female Shih-Tzu, died in January. She would have been 15 in February. We were very close. For example, after I returned home from knee-replacement surgery, for the first two weeks, she stayed by my side 24/7. After that, she would periodically check to make sure I was OK.

Two weeks ago, our vet asked if we would consider adopting an 8-year-old male Maltese who needed a home after his human “mom” died, and his human “dad” no longer wanted him. We met Dickens and his human dad at a park to see if we would consider adopting him. I was sitting on a park bench when Dickens came up to me, stood up on his hind legs, and looked straight at me. I swear I saw recognition in his eyes.

We agreed to adopt him. When we brought him home, he ran into the house and straight up the stairs to the second floor. It was like he knew the house. Upstairs, we have a TV room with two recliners and a wedge between them. Rosie liked to sit and sleep on the wedge. The first thing Dickens did was ask to be in my lap, then he jumped up on the wedge with no hesitation and settled down.

From the time we brought him home, he has followed me around and is always with me. He has also exhibited other “Rosie” behaviors.

Am I crazy? Is all of this coincidence, or is it reincarnation, or some kind of “group soul”? -- M.N., St. Louis, Missouri

DEAR M.N.: I think this is all coincidence, but reflective of the collective intelligence of dogs, which makes them behave and respond in the same ways in the same situations. I do not take this as evidence that animals have a “group soul,” as some Theosophists and others contend. It is more akin to Carl Jung’s collective unconscious in the human race.

We can mystify reality and wax spiritual, but existential reality is surely a wonder in itself. Every living being is a miracle of creation and survival, most animals having a far more ancient, if not more noble, lineage than we more recently evolved primates with the arrogance to name ourselves “man the wise” (Homo sapiens).

Our lives are often changed by the love of an animal, and also by the way we treat them when we give them equal consideration and respect. In doing so, we may earn the “Homo sapiens” title.

Australian aborigines have long known this, and proclaim of Australia’s indigenous feral dog, “Dingo makes us human.”

When your new dog first met you and you made eye contact, he saw trust and love in your eyes and in your body language. And as you entered his heart or spirit, he entered yours.

I SEE YOU-FEEL YOU

“Facial mimicry” is the term given to the empathic communication seen in the facial expressions of humans interacting face-to-face. One person smiles, and the other smiles. It is one of the pillars of human communication and intimacy.

Such mimicry is indicative of a high degree of social and emotional cognition and awareness, which are attributes of being human. But this behavior is not exclusive to our own species. Ethologists and comparative psychologists studying other animals’ behavior have documented this ability in other primates, as well as in dogs and wolves (as per my book “The Soul of the Wolf”).

Now, ethologists from the University of Plymouth, England, confirm that facial mimicry has been seen in sun bears. An article to that effect, “Facial Complexity in Sun Bears: Exact Facial Mimicry and Social Sensitivity,” was written by Dr. Marina Davila-Ross and associates and recently published in the journal Scientific Reports.

These Asiatic bears continue to be subjected to extreme cruelty as in the bear bile farms in China, where they are confined in coffin-like cages; the dancing bears of India, which are defanged, declawed and kept in chains; and bear-baiting with dogs in public arenas in Pakistan. These examples are all a sad reflection of our evident lack of empathy and the insensitivity and ignorance of unquestioned cultural traditions.

WHAT’S THE MOST DOG-FRIENDLY CITY IN THE U.S.?

Long Beach, California, was judged the most dog-friendly city in the United States, based on the availability of veterinarians, kennels, groomers, obedience classes and dog parks. Mesa, Arizona took the second spot, followed by Atlanta; Sacramento, California; and Seattle. (Newsweek, May 22)

DEAR DR. FOX: We have two senior springer spaniels with a sensitivity to fleas, and I have reviewed your articles on flea prevention for dogs. We are currently giving them Bravecto as a flea treatment. Living in New Jersey, we only dose them twice per year.

While we don’t like using this, it is the only preventative that has not caused side effects (at least, that we can see). Frontline and Advantix both caused vomiting and lethargy for a few days after application.

We almost lost our older girl to a hot spot that became infected, which our vet believes was caused by a flea bite. Any other suggestions? -- B.H., Trenton, New Jersey

DEAR B.H.: Many dogs get by OK with seasonal use of Bravecto, but I would never use it on my dog here in Minnesota. In India, we had to use Frontline all the time, and at least one dog had seizures.

I would rely on a flea comb after each trip outdoors; check for ticks at the same time, especially between the toes and ears. Best to avoid brushy areas where there could be ticks and fleas from other animals.

As a preventive measure, make a “tea” of one sliced lemon boiled briefly in 2 cups of water. Let cool and store in fridge. Apply to each dog with a sponge, getting the underbelly, legs, under the neck, and along the back, head and ear-tips. This will repel mosquitoes, fleas and ticks. Essential oil of eucalyptus lemon is also excellent, and you can make a spritz out of it with water, but cover their eyes when applying.

These natural herbal products have been used effectively for centuries but their use has been supplanted, and even outlawed, by the big pharmaceutical companies, which are in the human and animal health business primarily to make a profit. Their reticence to take action and recall or relabel drugs that have adverse side effects is a matter of public record.

As for Bravecto, and other insecticides widely sold in most veterinary clinics and some grocery stores, I am of the same opinion: These chemicals should only be used as a last resort. Eventually, insect tolerance and resistance to these insecticides will evolve, and using them year-round as prevention will accelerate this process.

Also, these products will not prevent biting insects from transmitting allergens, Lyme, heartworm and other diseases, as they only kill or sterilize the pests after they have bitten and fed off your dog or cat. For details, check my website (drfoxonehealth.com) for the article on this issue, “Companion Animal Risks of Flea and Tick Insecticides.” Dogs treated with such chemicals should be kept out of streams and lakes to avoid harming the life therein.

DEAR DR. FOX: My 8-year-old neutered tabby, Samson, has been coughing up fur for some time, and I find bits on the floor. In the early evenings, especially, he starts to groom himself, licking and pulling out bits of fur. Later, he coughs and hacks something terrible.

The veterinarian sold me some cat food that’s supposed to help stop furballs, but after two months, it’s made no difference, and he does not like to eat it.

What will help? -- N.McC., Fort Myers, Florida

DEAR N.McC.: It can be very distressing living with a cat suffering like yours, as I know from personal experience.

The latest instance was with our rescued “feral” cat Fanny, who left small tufts of fur around the house for several weeks. This stopped when she settled down and became attached to our dog, at which point she even allowed me to touch her when she was in her bed for the night.

My first question for you to consider is whether Samson is under some emotional stress. What, for instance, is going on in the home when he starts to pull out his fur? Either make it a quiet time or engage him in play to distract him.

Another two possibilities that your veterinarian should have discussed with you are food allergy/intolerance and thyroid disease. If a change in diet to one free of additives, fish, corn and soy does not help, then a blood test for hyperthyroidism would be in order.

For most of human history, we humans were gatherer-hunters with an intimate knowledge of the natural world. This knowledge was the basis of our animistic religious sensibility that felt and respected the life force in all things, as in ourselves, which gave us a sense of kinship with all life.

Lakota author Luther Standing Bear, in his 1933 book, “Land of the Spotted Eagle,” wrote: “The animal has rights -- the right of man’s protection. ... The concept of life and its relations was humanizing and gave the Lakota an abiding love. It filled his being with the joy and mystery of living; it gave him reverence for all life; it made a place for all things in the scheme of existence with equal respect for all.”

Missionary doctor Albert Schweitzer later echoed this spiritual realization in his philosophy of reverence for life, especially from the perspectives of world peace and disease prevention. I see this as the fundamental bioethical principle of One Health.

Contemporary religions have taken us away from such affinities with other living beings and the natural world, long condemning such views as primitive paganism, heretical to the divine order of man under God and man over all else. It is surely time to make amends to all indigenous peoples and species, and the natural environment that sustains us all.

DEAR DR. FOX: Our little mixed-breed Cavalier King Charles spaniel yawns widely every few minutes when she is awake.

She is a rescue, about 5 years old and 21 pounds, full of joy and playfulness. She eats well and seems healthy, but the yawning bothers me because I have never seen a dog do this so much. Have you? -- G.T.W., West Palm Beach, Florida

DEAR G.T.W.: Yawning in some animal species is thought to be a social signal of relaxation or a tension-reducing behavior. In humans, it may help cool the brain.

You have a breed of dog that can suffer from neurological problems associated with a skull that is misshapen in the back by the neck, putting pressure on the brain. This is called a Chiari type 1 malformation. It may lead to syringohydromyelia: a painful condition of fluid buildup in the brain cavities that can affect locomotion; cause pain, irritation and scratching of the shoulders, head and neck; and even seizures. Yorkshire terriers and miniature and toy poodles can also develop this condition, which can be treated with surgery and medication.

If your dog is showing no other signs of discomfort or neurological impairment, she may have a very mild form of this malady, or else her yawning has another cause yet to be determined. Yawning may indicate a lack of oxygen due to a heart problem -- common in small breeds, especially -- or low blood pressure.

Dogs, like humans, have mirror neurons in their brains that make them highly responsive to others’ faces and actions. Some dogs actually sneeze or yawn when a person in front of them does so, and so your yawning could be a trigger for your dog. Or else there is an external trigger that sets her off, and you need to note the time and conditions that might be a trigger, such as turning on the TV or other electronic devices. Some emit non-ionizing radiation or high-frequency sounds, which could upset your dog, who then yawns as a sign of anxiety or as an attempt to relax.

Another possibility: Is she doing it simply to get your attention away from the TV, computer or smartphone? These devices do affect how animals behave around us, and dogs, like infants, seek attention from their distracted caregivers. In my opinion, these devices should be used for very limited periods in both homes and workplaces because of the potential harm of non-ionizing radiation, as well as the potential damage to the brain development of younger users.

I never thought there could be so many reasons for yawning! I am sure there are more. In any case, a full veterinary checkup would be advisable.

ORGANIZATION WORKS WITH HOMELESS SHELTER TO COVER CARE FOR PETS

Nonprofit organization Pets of the Homeless works with Lighthouse Mission Ministries in Bellingham, Washington, to cover the costs of food and veterinary care for the pets of homeless people.

Allowing pets extends the shelter’s reach, says Lighthouse Executive Director Hans Erchinger-Davis, adding that having a pet brings feelings of safety and connection to people as they “start their journey towards health.” (KCPQ, May 9)

I hope more communities and civic leaders will pick up on this kind of good Samaritanism and extend their concern and compassion to people’s companion animals. The mental health savings are well worth the cost of helping the homeless and the poor keep their animals with them, and to help ensure they are kept well-fed and healthy.
