Just to give you all an update, I finally got up the guts to write her an email last night. This morning she responded, thanking me for updating her on the size, because was unaware of why she got such a large pup. However, she was willing to give me a 50% refund or a puppy to make up for it. She was very polite and grateful. I had gotten so worked up over it, thinking the worst...like she'd email me back using profaneity even I don't use haha
I'm not sure what I'm going to do, because her current puppies are another breed and I'm allergic to half of that breed...at least, I was sneezing after playing with them at her farm. She said she had a male yorkie ready to go in a few weeks, but I might want to wait. I'll talk with her to discuss options. I'm just glad we both handled it maturely.
Thanks for the advice, it really helped!
