dog adoption statistics

Need information on adoption professionals buy one more dog!?
Persausive I'm writing an essay about why people should adopt a dog instead of buying one, but I need facts to support it. For example statistics on the dogs to be kept in pounds, the benefits of adoption pet for the dog and owner, cons for the purchase of dogs (puppy mills, etc.). Thanks!
– Take: For these animals to be eligible for adoption, must receive a health inspection by a veterinarian and must have all their vaccinations. – PURCHASE: It's no secret that animals sold at many stores have been abused and not properly cared for. – Purchasing animals that breeders will only breed more and more, and continue over-saturation of the animals.
