I agree with the others, I would pay her and ask her to keep the puppy for at least a couple more weeks. Are the puppies weaned from their mom yet? They have to be completely weaned and able to eat on their own. I recently got mine at almost 9 weeks, and he has been fine -- but, he had been weaned and was eating completely on his own. If you decide to go ahead and bring one home, I would recommend that you keep Nutrical on hand just in case he/she doesn't want to eat at first. Mine didn't want to eat the first day, so I put a little cottage cheese on his food and he gobbled it right up.
Congratulations!!!!!
