Gary, he may be just associating the treet with food. If treets are going to work for you, regardless of whether you are trying to make him drop a toy, squirl, or something as simple as sit, he has to associate the treet with "i did good" set him up for success, get him to doo small tasks, and praise him real good, pet him up, rub his ears, whatever works, then give the treat. Make him understand that it is a treet, and not a tiny little meal, then when you give him one he will know that he did something good.
You have to train him to understand "treet" in order to use a treet to train him. So, if thos is a method you want to try, you need to keep lots of treets on you all the time, and use them allot!
Hope this helps.
