[Discussion] Something like an IQ Ball?

My Plott Hound/GSD mix has a very strong bite. He has a tendency to try and eat the food/puzzle toys once he has removed all the food. We had to get rid of one of them because he would figure it out right away, get all the food out, and then would try (somewhat successfully) to eat the ball. Big dog problems.Any suggestions on a more durable food/puzzle toy? via /r/dogs http://ift.tt/2qUsYTq
