Thanks for the comments all, Dawn is loving all the admiration

Diana, I too would have a hard time trusting a terrier breed especially since it is just in their nature to go after small critters. I'm sure some have coexisted just fine with smaller creatures, but it would be something like expecting a collie or border collie not to try to herd!

Tommy just utterly ignores Dawn, but Tasha is always curious and snuffling/watching her. She has never made any move to snap at her, even when she has flown by her a few times. That is the only time I get a bit nervous, when Dawn happens to fly by her head, but she rarely flies and Tash has never once given me cause not to trust her. I still probably wouldn't leave her alone with Tasha for any amount of time just for my own peace of mind. Willie used to stare and lick his lips when I had my had my RB parakeet, Bobby, out. That unnerved me so I kept them apart.

I do think Dawn is very brightly colored for a female. I actually thought she was a male for some time, till one day eggs appeared . I know Dawn is more a feminine name but that is what her coloring made me think of and in the end it ended up fitting her better than I would have thought.
