Anyone who breeds a litter of puppies is by definaition a breeder, but within our own ranks we then divide these breeders, into different catergories.
The 'pet breeder' somebody who produces one litter from a pet bitch hopefully with the guidance of their vet and the breeder of their bitch.
The hobby breeder as most of the members here are, we don't breed that often we do all the health checks, ensure the best rearing methods available are employed to rear litters, we do health checks, and other checks such as showing or working our dogs to maintain a certain standard of type and ability.
Then we have the 'puppy farmer'/'back yard' breeder somebody who breeds lots of dogs for money, open any edition of the Breed Record Supplement and time and again you can spot these people who live off their dogs. Yes some do test for health, and then some will carry on and use affected stock anyway, as they know that advertising their stock as tested makes people feel they are safe to buy from this breeder, there are the 'Rare breed' puppy producers who cross two pedigree breeds and call the resulting mongrel a cockerpoo or sprocker or some such similar name.
One last catergory the breeder who produces large guarding crosses and terrier type dogs for illegal purposes such as dog fighting or guarding drug houses.
The first two types of breeder do not make money on a litter of pups the latter? Of course they do, do they own up to the inland revenue or to the benefits agencies....... no of course they don't.
You can scrimp and save and do it on a budget, but you would not be producing a great number of puppies and would go into it knowing that it was going to cost you dearly, not only in money but perhaps in the life of your bitch and /or the puppies. As Schip says her vet bills were horrendous, but on disability allowance she can scrimp and save and breed a litter but I would bet good money Schip does not produce several litters a year and her puppies get the best she can afford.
So the original poster needs to define their question more thoroughly, so that we can give a proper answer not answers which are to a vague question where we have had to try to interpret the question being asked.
Did the OP want to know is it possible to claim benefit and breed a quality litter posibly a one off, or did they mean is it possible to breed lots of dogs and live off the income.
