That would be the worst reason to breed dogs. I'm sure some think just that way though.
I have had someone tell me they bred their dog to have puppies to give to family members. Well the dog died and so did the puppies. It isn't about just breeding and getting puppies.
Some people willt bred for the fast buck and have it backfire.
My last litter cost me about 250.00 after all expenses were paid not to mention my time which I get 37.80 an hour at my job. You should never be in it for the money but the love of the bred and to better the breed.
Having puppies to make ends meet is plain dumb
