Why why why why why?
Do your dogs do this?
(My two are teeny weeny which is why I let them up on the sofa... probably wouldn't if I had two German Shepherds...)
On the very rare occasion one of them has an accident for whatever reason (gets a fright, unwell etc) IT'S ALWAYS ON THE SOFA. Not on the hardwood floors which I could clean up in less than 2 seconds. Nope. On the black fabric sofa.
One of them has been sick today after scoffing too many treats off people at a pet show yesterday 3 times... 3 times ON THE SOFA. He wasn't even on the sofa, he jumped up just to be sick on it.
WHYYYYYYYYYY.
