Hi, I couldn't believe it when I read your message b/c we have the exact same issue w/ our 1-year-old Boxer/pit mix. He continues to bite myself and my three children. I don't want to hijack your post - but was wondering what your trainer ended up telling you and if it worked?? We have had Tyson for 4 weeks and are almost at the point where we feel he may need to go back to the Rescue. He has ZERO aggression - it's all rough play.
What is working for you (or any other readers)?
