The Secret to Finding a Lost Dog

Chevy-Koko

Few feelings of dread are as harrowing as the moment you realize your dog is missing.

Late Sunday afternoon, our long-time employee, Dawn Tate, experienced just such a moment. After hanging out with her two dogs, Chevy and Koko, in an open field near her home, Dawn realized that her Florida cur, Chevy, had not returned from her recent romp. Minutes later, as Dawn’s searches became more and more frantic, she realized that Chevy had vanished.

After a several minutes of fruitless searching, Dawn launched a full-out rescue attempt. Not only did she contact her local Animal Control Department, but also the police. Both agencies expressed concern for Chevy’s welfare and were only too happy to receive her emails with photos of Chevy, so they could keep an eye out. In addition to contacting the authorities, Dawn turned to social media for help. She posted images of Chevy and shared her last-known location with her friend network. Unfortunately, there were no sighting reports of Chevy.

Dawn was determined to bring her baby home, searching the surrounding areas as late as 2 a.m. and then was up before the crack of dawn to resume search efforts.

Thanks to a helpful friend, Dawn decided to try a recovery strategy that someone shared online. It’s a method that’s popular among outdoorsmen for lost hunting dogs. The trick is this … return to the location where you first became aware you were separated from your canine. At the scene, place at least one article of recently worn clothing (not anything freshly clean from the wash). The more scent it holds, the better. If at all possible, also bring along a crate or carrier and two or three of your dog’s favorite toys. It is recommended that you also provide a bowl of water (not food, as it may attract wildlife that might scare off your dog). You might also consider leaving a note for any people who happen by, requesting that the items remain undisturbed and why.

The basic concept here is that your dog wants to return to you, he just can’t find you. Thanks to their incredible sense of smell, they will be able to find their way back to these familiar items. Time and time again, this method has proven highly successful in reuniting lost dogs with their caretakers.

Why is it so effective? Dogs have an amazingly keen sense of smell. Their noses possess up to 300 million olfactory receptors, which is 50 times more than humans. To convert all of the sensory data picked up by these detectors, there’s a great deal of processing power. The canine brain allocates 40 times more brain power proportionately, compared to people.

It’s hard to quantify exactly how much better a dog is at detecting scents compared to ours. Some experts say it’s a 1,000 times better, while others say it’s one million times better. And humans actually have well-developed sniffers. All of us have had the experience of returning home and opening the front door to smell that someone’s been cooking. You were probably even pretty sure what dish was being made. If we can smell this, a dog could detect the same in a house the size of an average-sized city!

Dogs are able to pick up on a whole host of information from smells. When it comes to knowing their pet parent, they can read unique chemical markers (such as hormones) that we’re not even aware we’re emitting. With one breath, they can easily determine if we’re fearful, anxious or sad. That’s astonishing! Just remember, the next time you’re walking your dog and she lingers to smell the grass, she’s reading all sorts of information from the last dog that passed by. In this scenario, veterinary experts would say that your dog’s interior thoughts probably sound like, “Let’s see, you’re also a girl, you’re about 4 years old, you had a chicken-based meal this morning, you were super excited on your walk, etc.”

A HAPPY RESOLUTION

It was a frightening 24 hours, both for Dawn and for Chevy. But thanks to the innovative strategy we just explained to lure her back to the exact spot where they were separated, Dawn, Koko and Chevy are now safely back under the same roof. Yay!

Vitamin E for Stressed Pets

As a holistic veterinarian, I feel it is incredibly important to take the whole animal into consideration when it comes to nutrition. And, whenever practical, my preference is to provide nutrients, minerals and vitamins in their natural forms. In this post, I’d like to talk to you specifically about vitamin E, to review both the strengths and weaknesses of natural and synthetic forms.

Vitamin E is an incredibly complex and important nutrient that, among other things, functions as an antioxidant. Antioxidants are naturally occurring nutrients that promote health by slowing the destructive aging process of cells (a breakdown called “peroxidation”). In peroxidation, damaged molecules known as free radicals steal pieces from other cells, like fat, protein or DNA. The damage can spread, damaging and killing entire groups of cells. While peroxidation can be useful to destroy old cells or germs and parasites, when left unchecked, free radicals produced by peroxidation also damages healthy cells. Antioxidants can help to stem the tide of peroxidation, thus stabilizing free radicals.

Antioxidants like vitamin E are crucial to the health of companion animals of any age. They can improve the quality of the immune response and the effectiveness of vaccines in young pets, and help maintain a vital immune system in seniors.

Vitamin E occurs in one of two forms, either natural or synthetic. Natural vitamin E is a collection of eight chemically unique compounds that are derived from plants, including four tocopherols and four tocotrienols. More commonly used and less expensive, synthetic vitamin E is one compound – alpha-tocopherol.

For me, the choice of using natural or synthetic vitamin E in my formulas couldn’t be clearer, and neither could the evidence. The synthetic form of vitamin E is not as active or easily absorbed as the natural form of vitamin E. The molecular structure of vitamin E determines how well the body can utilize it. In human trials, researchers found that proteins in the liver specifically select the natural form of vitamin E and largely ignore the synthetic form.

In a Japanese study, scientists found that it took three times the amount of synthetic vitamin E to equal the blood levels of natural vitamin E. In the U.S., researchers found that body tissues and blood retained far higher levels of natural vitamin E versus synthetic. In addition, synthetic alpha-tocopherol vitamin E has only half the vitamin activity of the natural alpha-tocopherol vitamin E.

Why is there such a difference between synthetic and natural forms of vitamin E? The key to understanding how the body absorbs these two types differently lies on the molecular level.

The cellular structure of mammals more easily recognizes natural forms of vitamins. And cellular proteins and blood plasma bind to natural forms more readily than their synthetic counterparts. Unfortunately, synthetic vitamins are cheaper and, therefore, are more prevalent in many products on the market today.

So, how can you determine if the products you are using contain the synthetic or natural form of vitamin E? Simply check out the ingredient labels! Natural vitamin E is listed as a-tocopherol acetate, d-alpha tocopherol, d-alpha tocopheryl acetate or d-alpha tocopheryl succinate. Alternately, synthetic forms of vitamin E are labeled with a “dl-“ prefix.

Thank you for all that you do to make the world a better place for companion animals!
