Dog vs fence & neighbours

Quite obvious question based on that video. Just bought and moved and one neighbours has 2 dogs (staffy type) and they keep pounding at the fence. The fende is clearly getting damaged and I’m concerned it would break. I have 2 young kids. Neighbours are very stealthy probably because everyone around knows about their dogs we heard another neighbours screamed at them the other day. We haven’t done that being new in the block but now it’s clearly too much.

Will engage the neighbours as first port of call

However if no action is taken who’s ’at fault’ here and what’s the next step ?
