I'd bet it's a Rottie-Pit Mix; they're getting very popular especially in CT where I live and instead of getting a killing machine by breeding the two-you get a really big dopey, drooling dog that looks really mean.
We have a Husky mix dog, a Rat terrier and the big dope. And it's the terrier you have to look out for especially if there is food within a five mile radius. Buddy, the Rottie mix, is so lovey dovey he even helps his girlfriend take a bath-and she's a cat!
Chase runs rings around Ursa, literally, and knows she can get her way with one well-placed kiss on the nose.
Terriers are the only dogs that actually scare me. They're tough hombres.
