I have a big 2 yo male Whippet (agility dog) who tugs vigorously. My concern is when he comes running in from a bit of distance to bite, the amount of force with which he connects could be damaging to his neck. I accidentally got a photo of him at the moment he impacted the toy and his head and neck bent backward significantly. The toy was a Holee Roller ball on a bungee so there was a lot of flexibility in it - not stiff like a traditional tug. He has a definite bias toward this type of toy. I have since tried to employ movement rotating away from him so he has to collect and turn before letting him connect with the toy. But if my timing is off I’m afraid he will get hurt. Do the dogs involved in biting sports suffer neck injury?
