Due to their thin skin, a nip could mean a trip to the vet for stitches. At the same time, don't let a muzzle lull you into a false sense of security. You must still monitor a group of muzzled greyhounds since it's possible to catch ears through a muzzle. Many people believe that because of their structure and low body fat that they cannot swim. This is not true.
Some greyhounds are excellent swimmers.
Never leave a greyhound unsupervised near any body of water, including a pool, until you are confident that it can swim and can safely get out of the water unassisted. During their racing careers, greyhounds are fed a high energy diet to help them perform at their peak. However, retired racers need only a high-quality dry dog food with a protein content of 20 to 26 percent to provide nutrition and to prevent weight gain. This is usually a gain of 5 to 7 pounds. Some people assume that greyhounds, as an exotic breed, require extra care and special attention.
