I tend to believe byb's are ones who say "oops accident" or "but she is just sooooooo beautiful, she HAS to have a litter" Back yard dogs just sitting in the yard without a job... its a crap shoot what your going to get as far as temperment, ability, ect. Especially if the daddy is an unknown dog. BYB aren't breeding for a profit... I see alot of "free to good homes" or "small fee to take care of vet expenses". Hobby breeding is okay, thats different. But leaving your female dog in heat out were any male can get to her, or even letting your intact male get to her is not cutting it. The majority of the time the pups end up okay... But you don't get the assurance of genetic tests, orthopedic, eye, ear, heart, or appropriate breed screenings you get with a "standard" breeder. (hrrrmm couldn't think of the best word lol) I wish more people would spay or neuter there pet. I'm not playing devil advocate, because I staunchly defend breeding dogs, but some times its just saves the dog and owner a whole heck of alot of trouble. A dollar a day for 4 monthes (start saving with a pup at 2 monthes until its 6 months wich is generally the accepted date for spay/neuter) puts you well over 100 dollars. Just simply saying you can't afford it is not an option in my book.
