I have an almost 2 yr old person and a 9 wk old puppy. Gets kind of chaotic sometimes. Doing pretty good, my issue is jumping and biting. He has gotten better and not biting and jumping, and of course its expected, but he'ss a pretty big puppy. Any tips on training puppy not to bite an excited toddler? They play lots of fun games together, Kodiak only bites when they've been playing for awhile and are getting overly excited. I've been doing alot of mouth play with him trying to teach him good biting habits, but he bites hard when my son runs probably because he's moving so quickly. He does bite me hard sometimes too but he has gotten much better. It would be nice to be able to include Koen in the training, I heard of one technique the invisible puppy, pretending with child that puppy is invisible until he lies down, then give him lots of praise when he lies down and invisible again if he gets up. Seems kind of odd to me though, i dont need to teach him to lie down all the time, just not to jump and bite the little one....Any tips appreciated, thanks.
