Ok, when we got Aubrey, the shelter said she was between 1 1/2 and 2 years. The more I watch her, the more I feel she's closer to the 1 - 1 1/2 bracket. She has a lot of puppy mannerisms and movements, more than I think for coming up on 2 years. It's hard to tell without knowing what the other part of her pedigree is though. Is there any reliable way to gauge or should we just "go with it?" All the vet said was "She's young, anyway."
