It depends.
My aunt, whom hates dogs, makes holidays miserable.
I like to include my dogs in basically everything I do, including family get togethers.
None of my family has a problem with this, in fact, no one does except for her. My family loves me dogs, and they enjoy the enterainment of them doing tricks.

She's kicked them before and she's pushed them OFF THEIR OWN COUCH.

However, she's gotten a lot better about it since i've blown my top with her a few times about telling my dogs what to do.

Anyways.... as long as she's not there..

Christmas and Thanksgiving are my favorites.
She's normally not here for Christmas.... if we're lucky.
