The shower idea sounds like a good one. I bathe Zoe about once a week, sometimes more, and she hates her bath. Last night she bit me when I was washing her face. And I mean bit, not playfully at all. She shivers like crazy, fights the brush and comb and hates the dryer. I just have to keep talking to her sweetly to try to calm her down and it definitely helps. The groomer said she was sweet with her, but that they are like kids bad for momma but good with other people.
I keep telling her, she'd better get used to it. She's a YORKIE!!
Only concern with the shower is that if she likes it, she will be wanting in all the time.
She's such a brat!!!
