Greyhound owners and adoption groups generally consider greyhounds to be wonderful pets. They are pack-oriented dogs, which means that they will quickly adopt humans into their pack as alpha. They can get along well with children, dogs and other family pets. Rescued racing Greyhounds occasionally develop separation anxiety when re-housed or when their new owners have to leave them alone for a period of time (the addition of a second greyhound often solves this problem).

Greyhounds bark very little, which helps in suburban environments, and are usually as friendly to strangers as they are with their own family. The most common misconception concerning greyhounds is that they are hyperactive. In retired racing greyhounds it is usually the opposite. Young greyhounds that have never been taught how to utilize the energy they are bred with, can be hyperactive and destructive if not given an outlet, and require more experienced handlers.

Greyhound Adoption groups generally require owners to keep their greyhounds on-leash at all times, except in fully enclosed areas. This is due to their prey-drive, their speed, and the assertion that Greyhounds have no road sense. Due to their strength, adoption groups recommend that fences be at least 4 high, to prevent them being able to jump the fence and escape.

Greyhounds do shed but do not have undercoats and therefore are less likely to trigger people’s dog allergies (Greyhounds are sometimes incorrectly referred to as “hypoallergenic”). The lack of an undercoat, coupled with a general lack of body fat, also makes Greyhounds more susceptible to extreme temperatures, and most sources recommend that Greyhounds be housed inside.

Greyhounds are very sensitive to insecticides. Many vets do not recommend the use of flea collars or flea spray on greyhounds unless it is a pyrethrin-based product. Products like Advantage, Frontline, Lufenuron, and Amitraz are safe for use on Greyhounds and are very effective in controlling fleas and ticks.

It is often believed that Greyhounds need a large living space, however, they can thrive in small spaces. Due to their temperament, Greyhounds can make better “apartment dogs” than many, if not most, of the smaller hyperactive breeds .

In the late 20th century several Greyhound adoption groups were formed. The early groups were formed in large part out of a sense of concern about the treatment of the dogs while living on the track. These groups began taking greyhounds from the racetracks when they could no longer compete and placing them in adoptive homes. Prior to the formation of these groups, in the United States over 20,000 retired greyhounds a year were euthanized due to track injuries or simply because they were no longer of use; recent estimates still number in the thousands, with about 90% (highly questionable) of National Greyhound Association-registered animals either being adopted, or returned for breeding purposes (according to the industry numbers upwards of 2000 dogs are still killed annually in the US while anti-racing groups and other advocates estimate the figure at closer to 12,000).
