Our Aussie Just Started Nipping At Others
We have had our Aussie for about 1 1/2 years. In the last 2 months he has nipped at or tried to bite people that come to our house to visit. He doesn't do it to everyone and he only does it when their backs are turned. He will nip at their ankle or calf. He has NEVER tried to bite any family member but I am very worried that he might... Please help!! We LOVE our Aussie named Trigger! But from everything I've heard about dogs that start to bite it makes me worried that we will have to get ride of him. Any tips???
