Hello all, I know puppy biting is normal, and all of them do it but with my 3month old cocker spaniel, it is more than anoying. He doesn't bite when he's tired, only then he's full of energy, which still is normal. He bites alot, and grabs onto clothing. We yelp, we replace with toy, but that seems to keep it more and iresistabel to bite! He won't let go, and once you force him he is now starting to bouce back and bite more. He likes to jump and eat hair and bite noses and EVERYTHING! My parents r really consurned about what happened to my sis whos not even 10 yet. I was stroking him and my sis came over to jump on my back and say "PIGGY BAG RIDE!" Like she does a lot. Hugo then joined in and jumped on my back. I moved out of the way and said "NO!" While making him sit. He then ran over to my sis jumped on her back and aggressively tried to bite her, he was growling but it was def a play growl he jumped and bit her hair until she was actually screaming "Ah-ah GET HIM OFF! AAAA!" (she is a bit of a drama queen, keep in mind) my d came in and pulled him off by his neck, he then locked him out of the room and ignored him. Hugo HAS actually tried doing this to me several times, but I stand up and he just bites my leggings or jeans. He also likes to HANG ONTO my legs while trying to bite them.. which may be a sighn of dominance... Like I said, we've tried EVERYTHING! I know its hard... but is this normal? And, what should we do about it?
