I took Willow to PetSmart today (couldn't find the zen treats) and she acted like a fool. We haven't been out in awhile - which is probably part of the problem. She was ok at first just all over the place - pulling and not minding. Then she started growling and barking at other dogs with her tail all the way down. That is so not like her - she is usually very good at meeting people and other dogs. I don't know - do they go through some weird body snatcher teenage thing? Just was very much not like her. Maybe it was just too much. It was really busy in there today.
