I need help! I don't understand why my pup is excited (mostly in the mornings and late afternoons) she jumps up and she licks/tries to nibble on your toes. Ive tried telling her "No!", I tried yelping (she backs off then starts again) and I've tried doing that dog bark thing..and squirting her face with a water mister thing..none of it works properly though and it's frustrating. Can someone please give me tips on how I can stop her from mouthing and jumping up?
