So uh.... I was a little over-zealous and trying too hard in my last post about this.
I toned it down... let him just sniff the bag o' food... let him lick it.... moved it a little on the ground so he moved toward it....
Last night in our agility class he bit the bag and was TUGGING it! Hooray!
Who knew I could get so happy over a dog tugging on a mesh bag full o' hot dogs?
