Opie is a great dog with people, but likes to choose his own dog friends. He likes some males and some females. He does like to be the boss but can be submissive & playful with the right dog. Not recommended for children under 10. Opie is about 1 1/2 years old, crate trained, loves to chase Giant Kong Wubba's. Opie would be best for someone with a very active lifestyle or perhaps someone that likes to run with a buddy.
