I cannot speak to your specific problem because I have had both my B's since they were puppies. I CAN say, however, that my 3 yr old girl has never been attacked and is VERY dog aggressive. She goes into full growling-teeth-snapping mode as soon as any other dog {except Basenjis} come into sight. Even then, she gets a bit snarky with Basenjis also.
She's so bad we've been asked to leave the vet's waiting area because she was making so much noise at every other dog it was disturbing to people :eek: :o
It's not something I've worked on with her because other than vet visits, she really never sees other dogs up close so I just don't get the opportunity. I mean, most people aren't willing to take their sweet dogs on walks with Tasmanian Devil dog just to help the Devil Dog get over her problems :rolleyes:
I have been thinking that I do need to address the issue though, and next week am going to meet a trainer with an excellent reputation. I may just be talking as I'm not sure I can afford her, AND she lives about 40 minutes away, BUT maybe I can work something out.
Anyway, like I said, I can't be of help, but I know what it's like to live with a dog like that!
