I had a similar toy like this for my dog which he loved. The problem was it was plastic and after a short period of time he would damage it. 

Fable solved this. The exterior rubber covering has had this lasting longer than the previous too. He loves it. I put a portion of food in it daily and it keeps him busy for legitimately 30-45 minutes. 

One of the best dog toys I’ve bought. It’s a must have for a food motivated dog. Keeps him busy while working, watching tv, or whenever it’s raining and we shorten our walk.
