Pup not interest in doing commands if food isn't involved
Title pretty much says it all, but that's what I'm dealing with. I'm not sure if it is because he is still so young, but the few commands he knows (Come, sit, stay) he will do with about 85% accuracy as long as he knows he's getting a treat out of it. When I do the commands, mostly come, without a treat he will look to see if I have one and then if I don't he probably isn't going to obey. He isn't content with only praise as a reward. Anything I can do about this?
Another thing I'm noticing is he usually ignores me saying "No". I try to deepen my voice when I do it, but I'm a woman and my voice is high pitch - so it usually comes out loud instead of deep. What can I do?
