My son has a shepherd/chocolate lab mix that is absolutely hilarious outside when he gets near a particular big stick in the complex. He tries and tries to drag that stick to no avail, literally goes mental whining, barking at it, and carrying on like a spoiled child trying to get the stick to move.
On the bright side he is a fast learner, he does know his right paw, left paw on command, he prays for his snacks, speaks and does a host of other tricks. That dog will do anything for a bone.
