8 Month Old Australian Shepherd Nipping
My 8 month old Aussie is nipping at people. We just started an obedience class where she nipped at a kid and the trainer. She also nipped at the neighbor who got very upset becaue he has small kids. We plan to start an agility course at a facility next month but I am afraid she will nip at people. Any advice please on what to say or do about the nipping.
