I'm not really a first time dog owner, but this is my first time to have a puppy. I have a 2 month old-pup, a rottweiler-lab cross, and he likes to play-bite most, if not all, the time. I'm aware that this is normal for them, but it has become annoying since i get a lot of bleeding scrapes and wounds very frequently. He doesn't really bite hard, it's just that he's teeth are very sharp and pointy, with his canine teeth in the upper jaw almost as long as 2 centimeters. He's been with me for about 9 days, and I've been training him bite inhibition since day 2. Despite following all the instructions and steps in the thread "Biting Stops Here", I still can't see any progress. I introduced all sorts of chew toys I can afford to buy, but it seems he finds people's legs and feet more nibbly. I can't walk him, nor potty train him yet since his focus is always on play-biting. He's not interested in anything aside from his food and people's legs and feet. I wonder if his breed/cross has something to do with this behavior? Both his parents aren't really playful, so I really don't know where he got his obsession with biting. I have the patience to teach him bite inhibition for another week, it's just that, I can no longer tolerate the pain and the wounds I get everytime he bites. Also he's unlikely to let go even if I "yelp" or say "Ouch!" etc.. He doesn't respond to the training that much. I believe I did everything right, but I still can't see any progress. Will he ever outgrow this kind of behavior, or will it be like that until adulthood? Are there more things you can suggest on how can I decrease his obsession with biting people's legs?
