Hi! I can use some advice. We have a 10 week old standard that we brought home a week ago. He is extremely nippy and jumpy, especially with the kids. If they walk by him he will try and grab their clothes. He will jump on them and wrap his legs around them. He does it with my husband and me as well, but worse with the kids. He also tries to chew anything he can find, loves my couch. Is this normal puppy behavior? Could he be teething already? Please tell me this is just a phase 😂.
