Consequently, is your new puppy a puppy mill?
If the breeder has 30 puppies, that is definitely a puppy mill. Puppy mills don't like to spend money, it deters from profits. So the parents may not be vaccinated (you should ask!) and the puppies probably are not. Or, conversely, they have so many puppies they lost track and your pup got vaccinated twice.
Furthermore, do puppy mill puppies live long? Sadly, many puppy mill dogs will live their entire lives like this. They even breed in these conditions. This doesn't even scratch the surface of the other health issues your dog might have encountered. Given that there is no vet care or regular grooming, the list of afflictions is long.
Consequently, do all puppies come from puppy mills?
Roughly 90 percent of puppies in pet stores come from puppy mills. Many retailers who buy animals from such facilities take the wholesaler's word that the animals are happy and healthy without seeing for themselves. The animals produced range from purebreds to any number of the latest “designer” mixed breeds.
What do puppy mills do with unsold puppies?
As with other unsold inventory, they go on sale. Stores buy puppies for a fraction of what they charge their customers.
