I have read various posts about everyone using kongs and I felt a little dumb because i never knew what they were. Well my mom went to the store today and bought Chico one and also a bottle of this stuff called Kong Suffin (peanut butter flavored). I sprayed it in there and it just kinda rolls around in there. Is that what it is supposed to do? And what do you all put in your dogs kongs? Please let me know.....
