As with any dog, the Greyhounds are not genetically perfect.  Obtaining a puppy from a responsible breeder of quality animals is one of the keys to you receiving a healthy puppy.  Fortunately for the Greyhound, this breed is not extremely popular; therefore puppymills and backyard-breeders have not been attracted to mass produce these dogs. Thus the Greyhound gene pool is relatively healthy. They are however prone to a few medical conditions.

Bloat (GDV)
     Bloat must not be ignored.  If your dog looks "bulgy", is pacing with anxiety and drooling a bit, he cannot sit or lie down comfortably and is in general distress, get moving now, get to a veterinarian.
For more information, please see: Medical Index/G.V.D. or bloat.

Hypothyroidism
Hypothyroidism is the result of low production of hormones by the thyroid gland.  The symptoms can include skin and coat problems, sudden onset of aggressivie behavior, itching lethargy, musky odor, among others.  A simple blood test will determine if your dog has this condition.
For more information please see :  Medical Index/Hypothyroidism.

Anesthetics
        Greyhounds normally have very low body fat. This makes most Greyhounds particularly sensitive to barbiturate-based anesthetics. Be sure to discuss this potential difficulty with your veterinarian prior to any surgery.
