After watching Animal Planet’s ‘Houston SPCA’ and checking Petfinders - it’s clear that the animal rescue centers are making a fortune by closing down puppy mills & confiscating abused animals, with the assistance of law enforcement.
Their adoption fees are equal or greater than pet shops and abusive breeders. Because of the mandatory spaying - owners of rescue dogs have no option to continue a pedigree line from their pets.
Plus their write-offs and donations.
