I know your supposed to have a bigger female to breed with a small male. My new male that I'm getting is only going to be 2-3 lbs full grown. and I'm sure she would only have 1 puppy. maybe 2. but I wasn't going to breed her to sell the pups. I'm hoping she will gain more weight, by the time I breed her. If she doesn't then I won't breed her. that is what I was thinking of doing. but time will tell. and if not then I will get a bigger female or find a bigger female to breed my male with. so for right now we will say I'm not breeding her.
