We just did the fetch game again and he is really getting the hang of it! It is so much fun, and he is so cute

. I really think this kind of play interaction is what he needs. This is my first dog, so I'm still learning! But, I think a lot of his annoying behavioral issues might stem from not being played with/exercised enough. I think he is bored and that's why he is always nipping at our pant legs and barking at us. Glad I'm finally figuring it out! He is acting much better already. I did play with him before, but we only did about one short play time and one short walk.
