The ASPCA is not opposed to working guard dogs provided they receive proper treatment. Guard dogs should receive nutritious food, clean water, clean, dry shelter, and veterinary care, should wear a current dog license and identification, and receive sufficient socialization with people on a regular and frequent basis to allow for safe handling and an acceptable quality of life. Persons/businesses that train and/or sell dogs for guarding purposes should be subject and adhere to strict local and/or state regulations pertaining to the humane training and care of such animals.
