So, I have a black German Shepherd(possibly mixed)who is around 6 months old. Now, I want to teach him to stop nipping and biting before it becomes truly troublesome. Unfortunately, I have no idea where to begin. I've tried in the past, and each time did not go so well. All he does is jump on me and try to nip at my hands. Granted, there are times when he'll follow me around the yard with no problems. The yelping like a puppy method doesn't work, because...I have no idea how. I'd want to say the ignoring method worked, but I haven't had the time to really implement it. I mean, as soon as he starts nipping and biting, I go away. But, when I go back, he's back at it again. Should I just get him more toys to chew on, and if he starts to nip and such, replace my hand or foot or whatever with a toy? As well as the ignoring method? I know there is the crating method, but his crate is already too small for him. Are there any other methods that are actually effective? It just seems like everyone seems like an expert nowadays, so I have no idea who is right and who is wrong.
