New to the thread, but I'll jump right in, had a question for hellbender. We bought a puppy from a litter that was supposedly boxer mastiff mix at a no kill shelter here in upstate NY. Now that he's grown I know he isn't. I had a boxer before and he was huge, this dog isn't nowwhere near the size my boxer was. Last summer we took him for free rabis shots at our town hall. A guy in line asked what kind of dog we had, he said it looked like a cur to him, he was holding a catahuala cur (spelling?). When we got home we researched curs. He originally came in a litter from Tennessee, he's brindle, has a curled tail with a white tip, has four dewclaws, from what I read curs are one of the few dogs that do. He never calms down, super wired, runs like a greyhound. Seems to have a good nose on him, my boxer didn't. From what I read and pics of Tennessee mountain curs 50% are born with bob tails naturally and some are fawn and white colored like a boxer. Do you think they might have been mistaken if the mother looked like a boxer? I never get good pics cause he never sits still.
