Question about dog behaviour
So three years ago we adopted our female Lab/Golden, she was almost a year old at that time. She is a very sweet girl, excellent with the children, even if they get rough with her she doesn't do anything. She gets along very well with other dogs too, my father in law has two dogs around her size and she's great friends with them.
A few months ago, we brought home a smaller male dog (Jack Russell mix). She had spent time with him a few times before, and really enjoyed being with him. Now that he is with us, they get along excellent and spend a lot of time playing with each other. However, our Lab has a bad habit of grabbing the smaller dog by the neck and dragging him around, particularly when they are outside. She doesn't seem to be doing it aggressively...it's almost like she's trying to corral him as if he were a puppy wandering off. She never is ever aggressive with anyone, including him, but obviously due to the size difference I am concerned that she might be hurting him, or that this might be behaviour that needs to be corrected. He never complains about it when she acts this way, and I know he will complain if she gets too rough or if the kids accidentally step on him. Thoughts?
