A: I feel your pain, truly. And now let me add to it: dogs aren’t vengeful creatures. Your dog doesn’t have the capacity to understand your attachment to your couch; as a matter of fact, dogs think that particular bodily function is a pretty cool thing (hence their penchant for sniffing it out during walks), which blows the whole “canned food revenge” theory. However, there are a few realistic reasons that this happened: first, your dog may prefer high ground as a place to eliminate (some like tall grass, some like to be behind a shrub) and when he jumped on the couch he became excited, which can lead to elimination. Physical relief is a pretty strong reinforcement which is why this problem can take a bit of time and lots of supervision to do away with. There could also be separation anxiety issues, but without further details, I can’t be sure. My initial guess is that your dog has never been 100% perfect in the housebreaking department and that you’ve had other “surprises/shocks” before. No matter which one it is, they both carry the same plan: close supervision – no unsupervised field trips to the living room, confinement when you’re not home (his crate should make a come-back) and lots of rewarding when your dog uses the outdoor facilities. Follow those rules perfectly, and the problem will be, forgive me, eliminated forever.
