Puppy mills are usually characterized by their cramped quarters and squallid conditions. Typically dogs are mated every time their heat cycle rolls around, and their existence revolves solely around churning out puppies. They're mistreated and unhealthy.
That's what comes to mind when I hear "puppy mill" - how about you?
If you could write the definition of puppy mill, what would it be?
By calling a place a puppy mill, you're saying it should be shut down, that the laws apply to that place: so consider that when you answer. Also consider the state the dogs must be in for a commercial kennel to qualify.
Is a puppy mill a large facility where the dogs are locked in their cages all day long, fed little, and experience little human contact?
Is it a place where any number of dogs, even a few, are bred indiscriminately for profit alone?
Does it cover a backyard breeder who cares for her dogs and socializes them, but always has a litter available?
This is something I've been thinking about lately, so I'd like to hear your thoughts. :)
