Hello,
I'm experiencing exactly the same. My dog nearly 2 years now, becomes increasingly aggressive towards dogs and neighbour's.
I don't have an idea how to react to this.
I had already 3 times a dog trainer here, but so far none could help. The breed is very little known, also with the comportementalists. Very hard to find someone who can help.
I feel really desperate with this situation
