No, thanks. I like dogs well enough, but I decided I would never get a house dog when I lived in upstate New York. One winter, I had to leave home at the crack of dawn to get to an early class, and I still remember the sight of my dog owner neighbors outside walking Rover and Fido in the freezing cold with their overcoats thrown on over their bathrobes. I’d much rather clean two litterboxes.
I actually have a neighbor whose little dog uses a litter box. I’m not kidding.
But, I have to say, having worked for a vet and being involved with dogs for many many years, I have heard way more issues with cats and litter boxes than with dogs and housebreaking. Which is not to say you should trade your cats for dogs, just that, as an issue, I think dog problems are usually more easily resolved (because cats could give a tinkers damn what you think!)
