Since red blood cells carry oxygen to the muscles, this higher level allows the hound to move larger quantities of oxygen faster from the lungs to the muscles. Conversely, Greyhounds have lower levels of platelets than other breeds. Veterinary blood services often use Greyhounds as universal blood donors.Greyhounds do not have undercoats and thus are less likely to trigger dog allergies in humans (they are sometimes incorrectly referred to as 'hypoallergenic').
