maybe finding out the reason why your friend wants to breed her dog will help you persuade her to not do it. if it's for the dog's health. like she says, then try showing her and explaining to her that it's not healthier for the dog. and if it's for something else, like money, then maybe tell her that the costs involved...
sometimes it's hard to convince people not to do something they want to do...my neighbor breeds her tiny dogs, and she was surprised that i spayed my 3lb dog. she thinks it's nice to breed them and be able to sell them. (she is a BYB) when i tried to tell her that our dogs are too small to breed, she told me that she also owns the mom(~3 lb. also) who gave birth to the tiny dog that she is also going to breed, she thinks everything will be fine and thinks it's a shame that i spayed my dog...
it's even harder to tell someone they shouldn't do it if they had a successful experience with breeding their dogs once...i feel bad for her dogs. i can't imagine a 3 lb dog giving birth, i don't understand how her other 3lb dog was able to give birth with no problems, maybe she is just really lucky?
for her poor dogs sake, i hope she continues to be very lucky
