DEAR READERS: Several readers have commented about the demise of insects in their communities. As a veterinarian and a former Fellow of the Royal Entomological Society in the U.K., I have always considered the health and welfare of all species paramount, whether warm-blooded or cold. The loss of insect life is due in part to electromagnetic fields from power lines, cellphone towers and wireless services. These fields impact birds, bees, wildlife and our overall environment.

Combined with habitat loss and pesticides, the demise of insects and insectivores is the new norm of the Anthropocene epoch (our current era of significant human impact on the natural world). The consequences are becoming highly detrimental to agricultural productivity, the economy and public health, with the emergence of resistant species and strains of insect pests and carriers of disease, and the extinction of insect predators that previously controlled their numbers and helped maintain biodiversity.

The U.S. Department of the Interior addressed the impact of cell towers on migratory birds in a 2014 letter, saying: “The electromagnetic radiation standards used by the Federal Communications Commission (FCC) continue to be based on thermal heating, a criterion now nearly 30 years out of date and inapplicable today.”

DEAR DR. FOX: I’m getting a little dog soon and am concerned about vaccinations. The puppy is only going to be about 10 pounds when fully grown, and can’t handle the same shots as a dog that will get to 80 pounds.

Are the dosages of shots figured per the size/weight of the puppy? Do all vets factor in size and weight, or do I need to ask when I shop for a vet? What else should I consider when looking for a veterinarian? -- A.G., Tulsa, Oklahoma

DEAR A.G.: Many people, veterinarians included, are concerned about the high volume of injectable standard vaccinations for dogs, which manufacturers provide with no consideration for dogs’ sizes or body weights.

To inject a toy-breed puppy with the same volume of vaccine as given to a Great Dane is absurd. Also, giving vaccines by injection is not the ideal way of delivering immune protection. That’s because most infective agents (in other words, those not transmitted by biting insects, by a rabid animal or by a cat with feline immunodeficiency virus) do not penetrate the skin. Rather, they enter via the nasal or oral mucous membranes, or are ingested or inhaled.

Hopefully, safer and more effective vaccines will be developed by the pet industry -- an industry some see as being driven more by profits than by compassion, especially when it comes to addressing adverse reactions to vaccines and preventing their occurrence.

While ever-more vaccines are being marketed for humans and other species, I fear over-reliance on vaccinations has become a substitute for basic preventive health care measures and public education. My website (drfoxvet.net) provides a synopsis of basic vaccination protocols for dogs beginning in puppy-hood, and a review of the risks and benefits of vaccines.

GLYPHOSATE HERBICIDE IN PET FOODS

Eighteen major brands of cat and dog foods were randomly selected for a recent study, all of them being mixtures of vegetable and meat ingredients, with one being certified GMO-free. Analyses found that all of the products contained glyphosate, the main ingredient of Roundup, at concentrations ranging from approximately 80 to 2,000 micrograms of glyphosate per kilogram. (Jiang Zhao and associates, “Detection of glyphosate residues in companion animal feeds,” Environmental Pollution, 2018)

These levels are not considered harmful, but my concern is the potential harm to beneficial gut bacteria, which are essential for maintaining overall long-term health. The adverse consequences of disrupting this microbiome community, called dysbiosis, are many, and include inflammatory bowel conditions and allergies.

DEAR DR. FOX: A few years ago, my wife trapped, neutered and released a feral cat. We continued to feed it for about six years, with no problem -- until it was either killed by poisoning or by a coyote, as best we could surmise.

Why is that “seriously misguided,“ as you say? I would like to know, in case the situation occurs again. -- J.B., Palm Beach Gardens, Florida

DEAR J.B: There are several options for dealing with “feral” cats, which I have detailed in articles on my website, drfoxvet.net.

Many are lost or abandoned strays who once had homes, and are often adoptable when caught and rehabilitated. Others who do not become resocialized may have been fending for themselves too long to be “recovered,” or were born outdoors.

With such cats, the best solution is to trap them, test for diseases, then either euthanize or permanently quarantine those testing positive for feline leukemia and feline immunodeficiency viruses. Those not carrying these diseases should be neutered and vaccinated, and either placed in communal housing (where many do become adoptable after some time) or in designated sites where they are provided shelter, food and veterinary care -- with the proviso that no wildlife be put at risk.

You did your best for this cat, and I commend you -- my wife and I do the same, but bring the cats in for rehabilitation and adoption. I call this Step 3. Your Step 2 is better than the Step 1 where many people stop: just putting food out and not at least trapping and neutering to stop the cat plague. This is exacerbated by well-intended people who put food out for stray cats and let their un-neutered cats roam off their property.

VANDALISM AT SHELTER LEAVES DOGS SERIOUSLY INJURED

Vandals broke into an Arkansas animal shelter, released dogs from their pens, put some in pens together, and appear to have brought their own dogs for fight training, authorities say. At least one dog might not survive its injuries.

Shelter officials purchased security cameras after three dogs were killed in a similar break-in back in 2016, but the cameras were stolen before they could be installed, and the shelter does not have funds for a new security system. (WREG-TV, Memphis, Tennessee, Oct. 13)

I wept when I read of this atrocity -- not just for the dogs, but for the evident and increasing loss of our humanity and sanity in these times.

DEAR DR. FOX: My daughter wants to harness-train her cat.

She thinks a soft vest style is best, but at the shelter where I volunteer, they sell the PetSafe brand, which is the more traditional figure-8 style. They always use the PetSafe Easy Walk harnesses for dogs, which are wonderful, so I feel like this recommends the brand.

Have you any advice on this topic? Her kitty goes out on the balcony, which she has made safe for him, but she would like to be able to give him more stimulation at some point. So she wants to train him while he is still relatively young -- just a little over 18 months old now. -- M.S., Alexandria, Virginia

DEAR M.S.: I had a disaster with one of our rescued cats, who spooked when out on a leash and harness for the first time. He was able to wriggle out of the harness and ran off. It was early winter, and he was too scared to come back indoors. It took several days and long nights to encourage him to come back inside.

I advise getting a soft, full-body wrap-type harness, and also a collar, so he’ll have two leashes. Cats can wriggle out of almost anything when they have a mind to it.

Put everything on the cat indoors to start out right, and get the cat used to the pull of the leashes and feel of the harness. Avoid trying to lead the cat; cats prefer to lead and take their time slowly exploring when outside, even rolling in grass or dust, rubbing their lips, chins, temples and tails to mark various fixed objects and nibbling various plants.

Cats have excellent depth perception and are generally safe on upper decks, but initially, I would be cautious and have the cat wear the harness and collar on a safety leash before letting him out on the balcony.

DEAR DR. FOX: My dog loves to help me in the garden, but he will sometimes eat a slug or two, and he also likes earthworms. I know foxes like them, too.

Should I worry? Are they safe for him to eat? -- D.K.L., Fort Myers, Florida

DEAR D.K.L.: Your dog needs to curb this habit. Dogs get lungworm by eating larvae found in infected snails, slugs or frogs. They can also accidentally eat infected tiny slugs if they are on a toy or their fur.

The lungworm larvae then grow inside the dog, and adult lungworms move through their body to live in their heart and blood vessels. Earthworms may consume the eggs of roundworms in infected dogs’ feces, and then infect your dog when he eats them.

DEAR DR. FOX: This is my first time responding to any newspaper, but I have to say, the timing of your recent column was not happenstance.

We lost our beloved Maltese, Jazzie, just a little more than one month ago; she was 16 years old. This morning, I woke up missing her more than ever. There is not a day that goes by when she doesn’t come to mind. In my heart, I’m always smiling, yet tearful about the reality of her not being here. But this morning was a bit different; I had a real aching in my soul. And then I read your article about what our pets give us and teach us.

Jazzie was so much more than just a pet. She did indeed have emotions, and she could read ours as well. She had keen insight and knew when we were sick, tired, grumpy or happy, and ready for crazy, fun playtime. There was a time when I was quite ill and she never left my side, willing me to get well. She made us laugh and was always the best at turning our bad mood or stressed-out lives into joyful gratitude.

Yes, Jazzie was a part of our family, and will be forever missed. She gave far more to us than we returned to her, because she did indeed touch our souls. The Lord blessed us with this beautiful little one for 16 years and I’m praying there will be a time when we see her again.

At some point, I know we’ll find another little one to love. In the meantime, we savor our memories and the blessing of having had Jazzie in our lives. -- L.S., Naples, Florida

DEAR L.S.: Many readers will appreciate your heart-felt commentary about Jazzie. I just wish we humans could all show such love and devotion for creatures great and small.

DEAR DR. FOX: My 6-year-old Shih Tzu, Peaches, was diagnosed with struvite crystals in her urine more than a year ago. She was then put on Royal Canine Urinary SO prescription dog food (dry kibble only) for the rest of her life; I was told that she could no longer have any other kind of food, ever.

I just had her urine tested after a year of being on this dog food, and her crystals have returned. I have stuck to this regime since day one and am very concerned about the return of her crystals.

What can I do for my suffering little dog so that her crystals no longer return and turn into kidney stones? I thought I was doing what was necessary to keep her healthy.

Also, is there anything else I can do to vary her diet while keeping the crystals at bay? -- K.K., Sandy Hook, Connecticut

DEAR K.K.: Your veterinarian should go back to veterinary school -- to one that is not beholden to the pet food industry and does not brainwash students into accepting, without question, the claims and products of that industry, especially regarding so-called prescription diets.

Most dogs and cats generally find these costly diets highly unpalatable, and they’re prescribed for conditions often preventable with good nutrition to begin with!

To give any dog exclusively dry kibble -- especially one likely prone, for genetic reasons, to develop crystals in the urine that can damage the lining of the urinary bladder -- is absurd. The formula you have been giving her is high in salt, added to make dogs drink more water, which they need in order to keep their urinary tracts flushed out and the urine less concentrated (and less likely to form crystals). But in my opinion, this special diet is not the right solution, and could bring on other health problems.

Give your dog drinking water with some milk or some salt-free beef or chicken broth, which you can stew up yourself (adding 1 teaspoon of concentrate to 1 cup of water) and store in the refrigerator. This will encourage her to drink plenty of water.

Most importantly, give your dog a moist, whole-food diet, such as a quality canned dog food (like Cornucopia) or a freeze-dried food that you soak in water (like The Honest Kitchen’s). Or try my home-prepared recipe, posted on my website. Also, plenty of exercise, running off-leash at least twice daily, will help improve her overall condition. Far too many dogs, like their human companions, live unhealthful, sedentary lives.
