The operators of the two animal blood banks in California — Hemopet and Animal Blood Bank Resources International — say housing colonies of donor dogs, as required by the state, ensures a regular supply of safe blood for veterinarians. The owner of the facility in Garden Grove, Hemopet, said she has more than 200 greyhounds, former racing dogs shipped in from states including Florida, being housed for their blood. Greyhounds make up the bulk of blood donors at these facilities because of their generally docile temperament and their “universal” blood type, which can be used to treat any breed.
