Socializing Poorly

For a week we watched a dog that liked to pee on things whenever we'd leave, and sometimes when we were home, too. Carpets, shoes, its own bed, whatever. Even more annoying was how slow the thing walked. A 10-minute trip to get coffee would take 30 minutes. It was easier to pick it up and carry it, but then, you know, the peeing. I also found its quirk that it disliked other dogs odd. We'd see a group of dogs and their owners down the street, and it'd try to walk off in a different direction. I described the dog as "socializing poorly," but then I realized that I didn't really want to talk to the dog owner either, and it's not like I consider myself to have poor social skills. Maybe the dog is just cool with the friends it already has.
