Whining while playing tug
My puppy started whining today while playing tug. I just got a new tug of what I think is appropriate size and while playing he has started to whine. He is 6 months old and all the teeth seem to be in. Only been playing tug with him for about 2 weeks and has not whined before when we were using a bite rag and a tug that was far to large. He is still playing hard with full grip and a lot of pull. Wondering if anyone has experienced this before.
