OMG - I thought I was the only one in the world that happens to. Yes, happens.
Sabrina has always, always, since she was inches long, used my foot for a stool. But when we are visiting my parents who have a big Snauzer and a yorkie girl, she has wet my foot almost every time!
Then one time I went over without her - and the Yorkie girl (Mom's dog) wet my foot!
And I wear sandals 99% of the time. And I don't know what to do about it!
