I don't know,I think you should pass on this.The dog is only 2 mths old

she couldn't have had her more than 2 weeks

.Why can't she return her to the breeder(concern here)?she is young enough to be re-placed in a loving forever home.If she has all her papers and is utd on shots then she should also have a bill of sale and I would want to see it.I know you feel for her in this time but do not get taken.This just doesn't make sense, she buys a dog from an (irreputable) breeder(I say this because of her age) and within 2 weeks or less wants to give her up

.Didn't she know say 2 weeks prior she would be moving or evicted.I don't mean to be so negative but the circumstances bring up a whole load of other questions
If you go ahead with this I would have her accompany me to the vet and price her according to what if anything is going on with her.This just sounds so immature on her part(just because you have yorkies does not mean you are willing to take on someone else's oops).On the other hand this baby definately needs to be out of the home with her.
Whatever you decide good luck to you and just do your home work.
