I see a lot of questions here and on other sites answering the psychological hazards of tug, but I don't see anywhere discussing the physical.
I have a small Shih Tzu puppy, under 5 pounds (<2 kg) right now. She loves to play tug with me, and has gotten really good at it. At this point I can slide her around the floor all I want, but I am not getting the toy without making her drop it, or playing rougher than I think is safe.
Here are a couple of specific questions.
Do I need to worry about pulling the toy up? I feel like all the force goes on her neck, and I don't know if that can do some sort of damage. There is a lot of sudden movement from both of us as we play.
Do I need to worry about her teeth? She still has baby teeth, and a couple of times the rope slipped and I got it, I was worried about how rapid it was, and if I could pull out or chip a tooth.
From the dog's point of view she is having a great time, and is not in any distress from either aspect, but I am still concerned, as she wants to play tug for as long as I can handle. I want to make sure I am not causing any harm.
