Correcting needs to be done by everyone and it needs to be the same correction as well..The last thing you want or need is a confused puppy... :lol: You also don't want your kids to be afraid either....The yelping I found worked very well with Angel and she is 2, but sometimes gets a bit carried away in her play with me, so that's a reminder..Not all pups respond, so you may have to try a few different things...With Buck, he would nip my fingers as he walked next to me, which I wouldn't tolerate, so I would stop, kneel down, say "no bite" and touched my finger to his nose....After about 5 days, he quit..Yea, that was easy, huh? Also, when Tyson starts to jump, bark & bite and won't stop, a time out always works well..Not in a crate, but put him on his lead, have him sit next to you or tether him to a door knob for like 5 minutes and just ignore him...If he calms down, let him off and praise him for being good
