I hope someone can help. I have a new puppy (3 months). He's bouncy and playful and very vocal. The problem I have is that if he is a little hurt he squeals a lot. This seems to infuriate my older dog who is perfectly happy with him most of the time. The older dog then grabs the puppy by the throat and won't let go which causes more squealing. Has anyone experienced this? And what can I do about it? Will the older one really hurt the puppy? They are both male and both are teckels.
