When we would accept 'milk bone' treats from the bank, pet store, Sonic

Princess never ate them but would bury them in the couch in between the cushions that can't be removed, in blankets & she'd occasionally sneak into my dd's room-there are endless burying options in there.

Since she's on an Rx diet I don't let her have them anymore, knowing my luck she'd all of a sudden love them. So now she buries her tennis balls.
