I have a kong puppy for my 4 month old yorkie. It has these stick treats to put instead of the spray. I don't recommend filling the whole thing with peanut butter (that's super fattening, use the stuff they make for it) plus it would probably make a mess.
I really like the wubba it's like a covered kong with strings hanging off. Teddy loooves it, but he wont touch the regular kong unless it has a treat inside. |
