As you all know, I have a border collie who is difficult to amuse. I am particular about the toys i let her have, but I’m willing to try new things and let her have a go at just about anything once.
The Star Mark Everlasting Treat Ball, looks like a big chunk of rubber. However, when the special treats are inserted, the Everlasting Treat Ball becomes a long term source of amusement for your dog. The treat is shaped like a dome and is similar to a jaw breaker for kids. They can chew and suck and it dissolves very slowly.
Roxy loves to carry it around the room and chew on it in different locations. The ball will roll if placed on its side but it will sit flat and she can get good leverage to chew. It is latex and vinyl free and stronger than rubber. (Some dogs may be able to chew it), but its virtually chew proof.
The ball, and refill treats come in three sizes; small, medium and large. Amazon sells everything you need: http://www.amazon.com/StarMark-Everlasting-Treat-Ball-Large/dp/B0012V1G0Y
The other side of the ball can hold smaller treats too!
