Went to a girl's house once. Her (female) Dachshund sniffed me a little when I got there, otherwise no interest in me.

The second I kissed the girl, oh boy. Dog was straight over, barking her head off, walked over the back of the sofa and plopped herself in-between us growling. She knew exactly what we were planning to do and wasn't having it. Attempted cock block by a Weiner.
