Was very pleased with myself. He will now fetch his toys and drop them in/near his basket as long as he has treats and the basket is at my feet. Brilliant. Except today on our walk he decided to bring me all of the manky old plastic bottles he could find and drop them at my feet. If I moved, he moved the bottles. I ended up juggling bottles all the way home, and if I dropped one, he dutifully fetched it and dropped it at my feet. It looked like I was either littering on purpose but getting owned by my dog, or an insane sugar fiend. Any other tricks I should definitely not teach him?
