I allow my dogs on all the furniture. I figure, why not, we sit on it. They do however respond well (at least to me) to the commands "off" and "scoot" so they dont get first priority with couchtime. Likewise with my bed. Balfour rarely gets on this couch, so I couldnt resist when I saw them laying so nicely together.
I had to take Shiloh's bone away for a minute so she wouldnt be blurrily chewing in the picture, which is why she is licking her lips. But dont worry, she soon got it back with praise. Notice Balfour's new red collar as well. :)
