She's adorable! So glad she and Sim are getting along well now

As for her age, I think Tasha was around 4-5 months old when she first started losing her puppy teeth, I wouldn't think she could be much younger.. maybe she just has a smaller breed mixed in her, or maybe she's just naturally petite . I know Tasha was actually a bigger puppy, and we all thought she'd be bigger than what she turned out to be. The vet made his guess using an age/weight chart which according to that, it was thought she would weigh 60-70 pounds as an adult. I think it's a lot harder to guess with mixed breeds.
