About three years ago, one of my roommates who works for the SPCA brought home this monstrosity:
My roommate had gotten really attached to him, and he was slated for execution, so we gave him a reprieve. We don't know what he is, exactly...some sort of big terrier mix. He's about 115 pounds.
I have a fairly small house, and the dog is basically limited to three rooms: kitchen, livingroom, and computer room. We don't have a fenced in area to let him run loose, either. I've tried having him off the leash while walking him, but we're in a rural area with a lot of deer, and if he sees one he takes off after them. Thankfully, they'd always run deeper into the woods, but it's only a matter of time before he chases one out into the street, so I stopped letting him run loose.
He does pretty well indoors though. And I can proudly say he has never peed or pooped in the house. The biggest problem I'd say is that he gets hyper sometimes, and with a big dog and a small house, that doesn't always work! Sometimes he'll knock stuff of the coffee table. And when it comes time to take him out, he does his little "pee pee dance", where he hops and runs around in circles in a mad rush for the door. Sometimes he'll knock into one of our big stereo floor speakers, and once or twice actually knocked it over.
Oh, and he's actually cognizant of what's on tv. If he sees an animal, or even something that remotely resembles an animal, he'll lunge at it, get right up at the screen, and start barking. That can get annoying. Especially since I'll sometimes fall asleep on the couch with the tv on. It used to be, just like clockwork, I'd wake up at 5:00 every morning. That's when TVLand showed "Little House on the Prairie", and the dog would bark at the horses! And if that didn't set him off, well "Gunsmoke" came on at 6.
