I find our min pin is much happier when I keep him challenged by learning new things. So far I've taught him sit, down, wave (with both hands), high five.
He never really got the roll over thing or the sit pretty thing, I think it's hard for him because he's so long and gangly.
He also knows "leave it" but I'm furthering it by teaching him to leave a treat on the ground right in front of him while looking at me (not the treat) until I say OK! He's almost got that one.
He sort of knows how to crawl on his belly and walk on his hind legs but I wouldn't call it a trick, it's just him following a treat lure.
He started putting his toys back into his toy box on his own so we're rewarding that right now, kind of a trick he taught himself lol
What are some other tricks I could teach?
