I wonder if it's too early to say, but Tasha's exhibiting proper toilet habits. There have been appreciably fewer 'accidents' indoors, and she understands what 'going out' means for her to do. Good girl, Tasha!
Personality-wise, she's turning out to be rambunctious, energetic and attention-seeking, while at rest she prefers to be around people. All these traits are expected of dog behaviour.
I mention this only because her doggie behaviour is something the cats are not used to. So far, both Maui and Kaiser have taken swipes at her when she got too close. Certainly, these relationships bear watching. Hopefully, they'll adapt to each other quickly.
