Greyhounds and Body Fat
Greyhounds have a sleek, aerodynamic, well-muscled body with a limited amount of body fat. Which means that greyhounds have some special needs compared to other large breeds with more "cushioning!"
First, greyhounds are more susceptible to extreme temperatures. They are not able to stay warm in frigid outdoor weather, nor are they able to protect themselves from extreme heat in the summer. Even after being "fattened up" in loving homes, these dogs need a sweater or coat if they are going to be out in winter temperatures for more than just a few minutes.
Second, greyhounds can't metabolize some medications used for anesthesia during surgery or other medical procedures. Always make sure your veterinarian knows which medicines are greyhound-safe!
Third, less body fat means less cushioning over those hard muscles and bones. Always provide plenty of thick cushions, beds or blankets for your greyhound to lie on to protect elbows and other pressure points.
While it may be tempting to really fatten up your greyhound, too much body fat can shorten its life span and cause serious medical problems. Trying to put a big, rounded Labrador body on your streamlined greyhound isn't a good idea! It would put far too much strain on the hips, elbows and feet of your hound, causing early arthritis and rapid deterioration.
If you have trouble keeping weight on your perpetually thin greyhound, first have the dog checked for internal parasites or other health problems. If all checks out OK with your veterinarian, try giving your dog an additional 1/2 to 1 cup of dry food per day or try mixing in some plain, boiled white rice or vegetables such as peas for added bulk; often some healthy-but-tasty "mix-ins" will get even a picky eater interested!
