This happened to Edie recently. She was outside for a long time while I was in the bathroom getting ready for work. She came inside, and instead of playing with her toys as usual, she came straight to me looking very pathetic and embarrassed. I figured out what the problem was....
I first soothed her because she was so humiliated. "It can happen to anyone, Miss Edie....don't be embarrassed". Then I put her in the shower and gave her a warm pressure wash with the shower massage....worked like a charm.
Then I cleaned the shower.
Five years ago I never would have believed I was capable of doing this.
