Jack was 9 wks on Monday and is doing the usual puppy nipping at hands and feet. I've had puppies before and I have gotten him to stop biting me. His nipping at me is soft and doesn't hurt when he does do it. The same with my husband. He will sometimes bite my 5 yr old but not too often because we've instructed her on what to do in the situation, yell "no" and offer him his toy. The problem is with our 2 yr old. Their playtime is always supervised. If I can't be on the floor with the two of them together, then Jack has to be in his crate until I can give 100% attention. But he still always manages to bite her and I immediately correct him with a squirt of water or putting him in the submission hold. This only works for about 5 minutes and then he forgets that he isn't supposed to bite her. My thinking is that since she can't tell him "no" herself, Jack just doesn't understand that it isn't acceptable. I've never mixed toddlers and puppies so I'm not exactly sure what to do, or if I'm doing right and just need to wait things out. Jack drew a small amount of blood today and I'm wondering if there shouldn't be any playtime between the two for a while. I do make sure that when the kids are rambunctious, that Jack is in his crate since that seems to make things worse. I don't believe any of this is him being aggressive, just him being a puppy. (I'm training the 2 yr old too on how to behave with puppies and dogs but she is as bullheaded as Jack.) Thanks for any tips!
