Not tolerating other people handling her?

[sammgirl]

Huh. I think alot of dogs are like that. I know that shepherds are very one-person-centric and don't like to be in the company of strangers with out the benefit of having "mom" or "dad" there.

Mia just sounds like she's very bonded to you. If you want to loosen that a bit, I'd do doggy day care once or twice a week.
