There is a little female yorkie across the street from me. My Dexter seems to know when to go outside when she is.
One day I was taking him outside and he bolted so fast across the street I didn't even have time to put my shoes on. Needless to say, the little girl also has a collie in her house too.
By the time I ran across the street barefooted, lassie was on top of Dexter and Dexter was lying submissive on his back.
Sigh his little heart was broken so close to romance
