Did you know that ….
Greyhounds use More Muscles than other Canines …
A greyhound carries 55% of their bodyweight in muscle (compared to 45% in other breeds) and here are some important anatomical and physiological points to consider:
Two thirds of the body is carried on the front limbs, one third on the hind limbs. This forward gravity effect aids acceleration.
Muscles on the hind limb are larger and thus produce more power and strength.
The forelimbs have 80% steering function, 20% speed, with an important weight bearing and shock absorbing function.
Most limb extension is immediately prior to weight bearing, most flexion when the limb is in the air. Therefore the extensor muscles are stronger than flexor.
In addition to flexors and extensors, abductors and adductors contribute to limb movement, a complex interaction of a number of different muscles.

A greyhound draws in 60-90 liters of air in 50-90 breaths in a 30-second gallop, extracting 1500 mLs of oxygen from the air to metabolize the energy in its muscles.
During the gallop, the blood pressure in the lung arteries increases from 7 mm mercury pressure units at rest, to 40 units at the gallop, similar to the pressure peak in a human athlete, but only one third of the maximum pressure in a racehorse’s lung artery, which reaches 120 mm mercury pressure, or roughly 2.1 psi of pressure.
A greyhound produces around 100Kcals or 100,000 watts of waste heat energy during a 30 second race, sufficient to bring 600mL of tap water to the boil in around 2 minutes.
After a race, the gut function is restored over a 30 minute period to digest food, but the immune system is depressed for 30-120 minutes after a hard gallop.
Loading stress placed on the limb bones is repaired over a 7-10 day period after a race.
What a dog !!!!

How big is your Greyhounds BRAIN …

In Helmut Hemmer’s Domestication: The Decline of Environmental Appreciation (1990) ,is a very good discussion of relative brain sizes in different types of wolves and a different types of domestic dog. In relative terms, not all dogs have smaller brains than wolves.

Hemmer points out that the largest brains are in northern Eurasian wolves. Northern North American wolves have slightly smaller brains, but southern wolves have brains that are 5 to 10 percent smaller than the northern wolves.

Dingoes, which are feral dogs, have brains that are 25 percent smaller than northern wolves. Dogs from the tropics and East Asia have brains that are 15 to 2o percent smaller than those of dingoes. Improved Western breeds have brains that vary between those of the dingo and the East Asian and tropical primitive breeds, and some Western breeds, including the greyhounds and “some watchdog breeds” have brains that are proportionally the same size as southern wolves.

Hemmer then goes on to explain that brain size in European dogs was small from the Neolithic to the Middle Ages, and then, as the Middle Ages came about, Europeans began to breed improved dog stocks. Hemmer implies that this is why Western breeds have had an increase in brain size since then.

It is often said that domestication has resulted in smaller brains in domestic dogs. It’s actually much more complex than that.

Greyhounds have a Large Heart …

Fact.
The Greyhound heart is not only larger and more efficient than any other dog’s, but outperforms that of the Thoroughbred racehorse. During a 30-second run at top speed, a Greyhound’s entire blood volume is circulated through the body four to five times.

FDA Alerts Veterinarians and Pet Food Manufacturers about Potential Presence of Thyroid Hormones in Pet Foods and Treats

March 27, 2017

The U.S. Food and Drug Administration is advising pet owners and caretakers, veterinarians, and the pet food industry to be aware that pet food and treats made with livestock gullets (meat from the throat region) have the potential to contain thyroid tissue and thyroid hormones. Pets that eat food or treats containing thyroid hormones may develop hyperthyroidism, a disease that is rare in dogs and usually triggered by thyroid cancer.

Symptoms of hyperthyroidism include excessive thirst and urination, weight loss, increased appetite, restlessness, hyperactivity, elevated heart rate, rapid and/or labored breathing, vomiting, and diarrhea. Continued exposure to excess thyroid hormones can cause damage to the heart and in some cases, death.

The FDA is issuing this alert now after a recent Center for Veterinary Medicine investigation into reports of three dogs in different households that showed signs of hyperthyroidism. In these cases, extensive testing on all three dogs conducted at a reference laboratory showed elevated thyroid hormone in the blood, but ruled out thyroid cancer. Reference lab interviews with the dogs’ owners revealed that all three dogs had been fed BLUE Wilderness® Rocky Mountain Recipe TM Red Meat Dinner Wet Food for Adult Dogs and/or Wellness 95% Beef Topper for Dogs.

Based on the recommendation of the reference lab’s consulting veterinarian, the feeding of these dog foods was discontinued. After the dogs stopped eating these products for a few weeks, their clinical signs disappeared and thyroid hormone levels returned to normal. An FDA lab tested unopened cans of BLUE Wilderness® Rocky Mountain Recipe TM Red Meat Dinner Wet Food for Adult Dogs and Wellness 95% Beef Topper for Dogs and confirmed that they contained active thyroid hormone. The source of thyroid hormones is likely from the use of gullets from which the thyroid glands were not completely removed before adding to pet food or treats.

After consulting with the FDA, both WellPet (the maker of Wellness) and Blue Buffalo (the maker of Blue Wilderness) initiated voluntary recalls of select lots of the affected products on March 17, 2017.

WellPet voluntarily recalled of certain lots of 13.2 ounce cans of Wellness 95% Beef Topper for Dogs with best-by dates of 02 FEB 19, 29 AUG 19, and 30 AUG 19 printed on the bottom of the can. The UPC Code is 076344894506.

Blue Buffalo Company voluntarily recalled of one lot of 12.5-ounce cans BLUE Wilderness® Rocky Mountain Recipe TM Red Meat Dinner Wet Food for Adult Dogs with a best-by date of June 7, 2019 printed on the bottom of the can. The UPC code is 840243101153.

The FDA appreciates the cooperation and swift action taken by both firms to address this issue. If your dog has eaten either of these foods and is showing symptoms of hyperthyroidism, discontinue feeding of these foods and consult your veterinarian, making sure to provide your dog’s dietary history, including what the dog has been eating, how much, and for how long.

Consumers who have any of the recalled food should not feed it to their animals and can refer to the company press releases for further instructions about returns/refunds.

Questions about whether a particular pet food or pet treat product contains livestock gullets and/or thyroid hormones should be directed to the product manufacturer.

The FDA provides more detailed information about the issue of thyroid hormones in pet food in its Letter to Veterinary Professionals and Letter to Industry.

In the hopes of saving even one Greyhound from what happened to Bailey yesterday, Jody and Peter would like to share this information with as many Greyhound owners as possible:

My vet called to let me know that in reviewing this incident along with another last week (where it occurred more slowly and the greyhound was able to be saved), they have done research and had a consult with Tufts Veterinary School and found the following: While it is rare, greyhounds are the only breed that has been observed to have an unexplained increase in potassium level while anesthetized, especially after being under for about 1.5 – 2 hrs. In both Bailey’s case and the case last week, they discovered an extremely elevated level of potassium even though the level was normal just before the procedure.

They gave calcium to counteract it in both cases, but were unable to reverse it in Bailey’s case. In the case last week, they had enough warning with heart rate gradually slowing that they ran a test and discovered it in time to reverse it; in Bailey’s case it was too sudden for the treatment to work (they only even tried it because of the incident the week before).

This apparently has been observed in only greyhounds (rarely) but the mechanism of what is happening is not understood. My vet has decided that they are now going to start doing istat tests for electrolytes at one hour in and every half hour after that during a procedure whenever they have a greyhound anesthetized in order to try to catch this phenomenon early and reverse it before it causes a cardiac incident.

Please share this information with everyone you can in the greyhound community and hopefully we can prevent at least some greys from dying this way.

Heatstroke in Greyhounds:  What You Need to Know


By Judy Kody Paulsen, Founder of Greyhound Companions of New Mexico

I am grateful for the help of Suzanne Stack, DVM, in preparing this article. Dr. Stack is a 1985 Ohio State graduate currently practicing near her home in Yuma, Arizona. Previously, she served as a State Racing Board Veterinarian in Wisconsin and as a track vet in Texas at Valley Greyhound Park. Dr. Stack worked closely with Arizona Adopt a Greyhound (AAGI) for a number of years and still volunteers with that group.

The relative lack of information on canine heat-related and exertional ailments is alarming, considering how common the occurrence is among dogs of all breeds, particularly greyhounds. Not surprisingly, there is contradictory information on how to handle these sometimes fatal catastrophes.

Racing greyhounds are finely-tuned athletes and are usually conditioned by professional trainers. A racer’s performance while training and racing is (or should be) closely monitored. The onset of heatstroke or another debilitating and potentially life-threatening muscle disorder called hyperacute exertional rhabdomyolysis (HER) are two things no trainer wants to see.

Varying degrees of heat/exertional illness require specific treatment approaches to avoid permanent damage to muscle fibers, kidneys, and other organs. An experienced greyhound trainer has the expertise to recognize when a greyhound has been afflicted with one of these medical crises and knows the urgency in administering appropriate treatment.

Once the greyhound has left the racing environment and is lucky enough to be adopted, there are still numerous perils to which the dog may be exposed. One of the most common, yet least considered dangers, is that of over-exertion.

Well-meaning adopters want to give their greyhounds freedom to run and exercise, but it must be understood that unlike humans, dogs do not possess the ability to gauge their fitness and adjust their level of effort accordingly. Retired racers, depending on how long they’ve been off the track and how compromised their physical health might be, are at serious risk for experiencing critical problems when allowed to over-exert themselves.

A P.S. from Judy:  Something I did not mention in the article is the value of having a surface temperature gauge (STG).
I was interviewed last year for a TV news piece on keeping dogs safe in the summer, so I took along my STG to meet the journalist at a dog park to see how hot those surfaces can get.  One of the surfaces (synthetic grass) measured 191 degrees!
