There are hobby breeders, and business breeders, then back yard breeders, and puppy mills and everything in between.
Business breeders are breeding for a living, and sometimes, there is nothing 'wrong' with it. They breed and show and offer stud services etc.
I consider (or will when I actually have a litter) myself a hobby breeder. There is no amount of puppies Ruby could have to recoup lost monies, unless maybe she has 16 puppies per litter and I breed her 10 times! Definitely not a business breeder.
Like everything else, you have to really do your research on the breeder. My breeder has 5 labs & she is friends with Mary Howely of Candlewoods Kennels. Her first lab was from from one of her labs. She only has 1 litter every year or two. Her labs live in her house. But she always has a waiting list for her labs & all the clearences are done, hips, eyes, elbow & her labs are on the white list for CNM.
Her labs are field labs & all have titles. She breeds also for temperment & is very selective when looking for the stud dog.
Those are the questions I would ask....does the dog have all the clearences, what does the breeder do with their labs? It is always good to see the parents. Check the pedigrees.
There is truly no guarentees, but getting a pup from a reputable breeder, who has done all the clearences & you can see the temperment of the parents, does give you a better chance of having a healthy puppy.
I don't breed, my females are spayed, but I have leasrned from the forum just what to look for in a breeder, whether they are a "hobby breeder or a business. But I would like to say....it is an expensive hobby when done properly.
I think as long as you make sure the breeder does the clearances, doesn't breed the dogs too often, doesn't keep a shload of dogs where they have a litter ready every month, shows and trains their dogs, belongs to clubs....you'll be fine.
Where are you located, we will have a choco litter available in Feb if the Puppy-gods are looking down on us!
