Hi! I myself have a 6 month old puppy that loves to bite but ever since we started taking him to the dog park on a daily basis it has reduced. Also he has stoped teething. We got to a point were he was biting everything in site but then he was loosing his puppy teeth. I would find them all over the place. So he may be going through that stage. But I find that the dog park has done him good as I live in an apartment and do not have a fenced backyard for him to run in. At the park he is able to run around with other dogs and wear himself out. I started in the small dog section but he would be the only one most of the time so we have moved to the bigger dog section and he runs after the bigger dogs. It has also helped in socializing him with other dogs. I myself live in houston and there are a lot of dog parks that you can go to. And as he plays with other dogs, you can study for your classes. This has helped us greatly as for the moment we can't get another dog; although that is my goal. We take him at least 5 days a week. Hope this may be of help to you.
