Jackson and the pet sitter

Jackson has been hunting.... I tried to get his paws clean. Jackson went into serious hunting mode the minute he went outside.  He of course found something (I heard it squeak.) He immediately starting sniffing, shoving his nose in between the stone wall and then the digging began.  So after I tried calling him a few times, I had to go over the where he was to get his attention.  Finally I said "treat" enough times for him to stop.  I really did wipe his paws off... :(
