Hot Rod does the same thing. He can't gobble his Zuke's treats up fast enough but when I give him a biscuit, he just drops it somewhere and starts burying it. He doesn't even really try to eat it. It was funny, we went thru the back drive thru window and the teller sent a treat back (I had to chuckle-this was my first experience with this as he is my first dog) but Hot Rod just buried it in the corner of his seat! I forgot about the treat and the next time we got in the car...he pulled it from 1 spot and buried it to another! I finally threw it out...I could tell if he was saving it or trying to get rid of it.
