I know how you feel too! I got Thor when he was two years old. On the other hand, I'm not sure I would have had patience for him as a puppy. It's been quite the ordeal to get him potty trained as an adult, I don't know if I would have lived through it as a puppy.
Thor's former owner told me that she bought him from a pet store in LA specializing in tiny dogs(!). She said he had a sister with him. I wonder what happened to her too. I hope she is in a good home now.
Also... I must admit that sometimes I wish he could be a daddy, even though I know he's not a good representative of the breed. He's just so cute and I bet his puppies would have been too. Don't worry everyone, he's neutered.
