I try not to get dragged into these threads, but the key thing to remember is that a 'puppy farm' and a 'commercial breeder' are very different.
Puppy farms - unlicensed, dogs cramped into cages, stables, back to back litters, poorly puppies taken too young, living in their own faeces, never having human contact.
Commercial breeders - licensed, follow animal welfare regulations and rules on living areas, numbers of litters, space between breeding, age of bitches, socialisation, vet checks, vaccinations, microchips etc. Yes, the dogs may live in kennels, not on a sofa, but they are clean and well cared for. Yes they may breed several litters a year, but you have to remember this is essentially a 'business' and they need to cover costs. Setting up the sleeping, living and exercise spaces, heating, lighting, whelping area, vet checks, license costs etc all adds up and its not financially feasible to just have the one litter a year. But that doesn't mean they are putting the money before the welfare of the dogs.
Now, not everyone may agree with commercial breeders, but they are not the same as puppy farms, and the puppies grow up into healthy, well rounded pets with no problems.
And not all crossbreeds come from puppy farms - that's my favourite line...
