Aww....she's so cute! I have 2 Dachshund puppies that we got at 6 weeks and 1 day.
They were also too young to be away IMO, but the owner had to get rid of them. Luckily with 2 of them (brother/sister), they play and learn the not to bite too hard stuff.
How does she like that collar? Mine are still getting used to wearing one....we didn't put them on until they were like 8 weeks or so though...they were just too small.
What's her name?
