how do you make peanut butter dog treats that beagles enjoy?

my dog loves peanut butter treats, except i can't find one that he enjoys.have any ideas?
i have fed my dog peanut butter treats, but he got tired of the same treat. so i got peanut butter treats at the store, and he doesn't enjoy them. but i think that he loves peanut butter.thanks!

No I don't.

But I know almost every dog would rather have raw chicken hearts and gizzards. They are great treats, are a good size, and dogs go crazy for them.
