jenny1:When so much money is involved in breeding puppies, its no wonder there are such sad cases about.
The costs of making sure that the parents are good representatives of their breed, genetic testing, health checking, choosing a genetically compatible mate, pregnancy checks, food, worming, fecals, well puppy checks, socializing, and puppy care training materials makes raising puppies an expensive proposition - if you do it right. C-sections, other whelping complications, sick puppies, and small litters make the chances of having a profit even smaller.
The folks that don't really care about the dogs and puppies skip a lot of stuff to increase their profits. That makes the new puppy owners more likely to wind up with unsocialized pups with current health problems or health issues in their futures. Dead dams and puppies are just part of the cost of doing business.
IMO, the best place to get a puppy is from a dedicated, small, hobby breeder that produces 1-2 litters a year or less. Start a new thread if you would like to hear from some of those folks about whether or not they make a profit.
