Tango may have 3 legs to work with but he tends to prefer walking on 2 when he's excited about eating. Last night he had a large dinner because we missed lunch and he was exceptionally excited about his egg/raw kibble combo.
This morning he also walked for his breakfast though he was pretty talkative about it. I'm trying not to encourage his vocalizations during these times because I don't want him barking/yipping and expecting to be rewarded for it. I wait until he's mostly quiet before rewarding him with his meals.
