1. I have trained him personally using positive feedback methods.He is generally good with good recall. I will admit that he has been hard to train and he definitely has a different personality from my last boxer who was completely passive and would only rise to a challenge from another dog if really pushed. Louie was also neutered at 6 months and was very ill following this . He ended up in ITU in the vet hospital for a couple of months with necrotising fasciitis and septicaemia and we almost lost him then. so he didn't have an easy start in life
2. the attack occurred just over two months ago
3. He wasn't on a leash at the time. We were going to pick brambles in a field near my old house which is fairly rural I did not expect to see another dog there. My dog approached the other dog in a friendly manner I never thought anything of it because he usually gets on well with other dogs . He liked to have a run about with them. The attack was completely unprovoked. The dog bit into his rump and wouldn't let go . It was very traumatic for him he was in a lot of pain and was so shocked after that we had to take him to an out of hours vet.
4. Not in general but there is one dog that he is aggressive to when he is on the lead. A chocolate lab! My son says that this dog provoked him before but I wasn't there and don't know the circumstances, but if I see the dog I have to put him on the lead. He hasn't gone for the dog but I wouldn't give him the opportunity
5. He has had no formal obedience training
6. since the attack I have seen him be aggressive on one occasion . We live opposite a small park where a lot of dogs congregate with their owners or walk round the park. He plays now but is a bit more reluctant to join in. During this episode I was with other owners and the dogs were playing with balls frisby's etc . he was sharing his toys with the other dogs and there were no signs of aggression towards any of them despite a couple of skirmishes between the other dogs. Another dog who had been walking with his owner came over to the group. They had a sniff at each other and louie tried to mount the dog. The dog snapped at louie and louie growled and chased the dog. I called and he came straight back to me, but I was upset that he had displayed this dominant behaviour with the dog because I felt he wasn't 100% under my control at the time. My partner said that he had displayed similar behaviour with another dog whom he used to play with when he was a pup. another chocolate lab.
7. If he displays any aggression I tell him he's been bad, put him on the leash and take him home, so his walk is cut short. Usually I tell him he's a good boy when we are going home and make a bit of a fuss of him but I don't give him any attention at these times.
7. We have a completely fenced garden
