My dog actually performed an impressive bit of problem solving that has interestingly led to the “sit” command having two meanings that differentiate from each other based on whether or not he has a ball in his mouth.
Being a very bouncy boy whenever he is not in lounge-mode, my little fella sometimes wants to make getting the ball away from him when we’re playing fetch into an extra part of the game. Now I’m not here for that since he has some big ol’ teeth and has accidentally nipped me hard while adjusting his grip on the ball as I try to get it back. So it’s better for everyone to have the ball gotten calmly.
So I decided to try asking him to sit to make getting the ball out of his mouth easier. Pretty quickly he figured “sit” was just a prelude to him giving me the ball.
Thus, under normal circumstances, “sit” is asking him to sit. When he has a ball, however, “sit” now results in him dropping the ball at my feet and it will take a second “sit” after the ball is out of his mouth to get him to park his behind.
He does not comprehend “drop” in regard to balls, only to clothes he has smuggled out of the hamper because I did not shut the closet door. Balls getting dropped are now always “sit” for this little guy. Weirdo.
