Might want to try the Busy Buddy Squirrel Dude by Premier. Very tough to get the food out of with the little flaps inside the opening. I would get the Large or extra large size depending on your dogs size.
Very tough toy. And yes..our dogs do excel at those things they spend a lot of time doing. So perhaps a bit of trick training or obedience each day would help with mental stimulation. Trick training and Obed. games don't need to take long. 10-15 min. a day .
Dogs do get slab fractures from any weight bearing bones if they are aggressive chewers.
My Squirrel Dude toys have lasted through many dogs.
