Loki is 10 months we got him at 6 weeks. He is the third generation of his family born in the USA. He is even tempered and easy going. He knows most of his toys by name. He knows no, sit, down, wait, come, out (as in give up the toy), bark, bring, heel (not too well), load up and find it (the toy). Crate trained but is showing some anxiety about us leaving him home alone. He stays alone in the car for an hour or so no problem. He doesn't like to work on a collar but is fine on a harness.
