Yup. I have a now-5 year old. He was rough with our dog just a few times and we put a stop to it. It’s not fair to the dog and it’s not fair to let the kid think it’s ok to yank (and yank, and yank) on a dog’s chain.
OK I saw it. So she did a little in the broadcast, but no big deal. She wasn’t “yanking-yanking-yanking” as if constantly truly yanking it hard every few seconds. Just a few continuous tugs, part of which is obviously her understanding of directing him to do certain things when he doesn’t understand her talking.
