I love things like this. My horse Tango loves to lick me, especially after a peppermint (the star kind you get at restaurants), and will sit there and lick for literally 30 minutes. My arm, face, hair, shirt, whatever. LOL. He also has licked Gracie, but when she tried to return the favor, he got a tad...concerned. LOL.
Potato looked like there was not a thing wrong in the world...and honestly, there wasn't. For either horse or dog. LOL. Thanks for posting.
