Okay so there have been new developments that make me shake my head.

1) The next day my SIL (sister-in-law) went to pick up the mutt (they had already put $100 down) and the thing bit my niece and the SIL went nuts and demanded her money back. The owner refused (shocking) and said "It's a puppy what do you expect?" So they did not get that mutt.

2) SIL went on petfinder.com and saw all kinds of puppies on there. She applied for it and was approved. This pup is a Boxer/English setter mix. I read the descriptions on both dogs out lout to both. Stressed that they need a firm consistent owner and need a 45 minute walk every day. The rescue said the same thing. My SIL was like yeah yeah, "Gabby" wants a puppy. When I saw this puppy... the thing is 2 months old and is already 7 lbs. The thing is huge! I work as a vet tech, I know puppies! But SIL was still insistent that it'll work out.

3) Three days later today, my SIL is trying to sell the dog online for $300. I am very annoyed because the rescue told her "If there is a problem, please bring the puppy back. No questions asked, no problem." But my SIL is not going to get her $400 back so she's trying to sell it. She's all happy that someone on craigslist.com wants to buy the puppy. She has no idea who these people are! Omg. The stupidity is astounding!
