Neighbour won't pay their half of housing association fence

My understanding of it is that the dog owner  legally has to keep their dog under control at all times. If he ventures into your garden then it's not under control and potentially tresspass and a criminal offence. Id take your dog into your garden on a lead until the fence issue is sorted. If their dog tresspasses then I'd take photos or video as evidence. I'd write to the HA with said evidence and strongly suggest they enforce the neighbour to secure the boundary to prevent further occurrences.  I'd potentially get the police involved too. Write to the neighbour and post it and keep a copy of the receipt, informing them about your expectations for them to keep their dog under control until the fence payment issue has been resolved satisfactorily and the fence errected. Yes this will cause tensions but they are being unreasonable not paying their half. Hopefully the HA can strong arm them. 
Unfortunately ive had this issue myself. Not HA but neighbour kept promising to fix thier fence that was constantly blowing down and falling apart. They never did. I was the one with 2 dogs. I ended up paying 2k to put up fence on my boundary running alongside theirs as couldn't keep risking the dogs getting out. Definitely wasn't impressed but unfortunately the law states you just have to mark your boundary not have a fence in place!! Although now I have a lovely new fence instead of an eyesore.  They have started to removve their fence panel by panel as it blows down! I will definitely not be allowing them to attach their washing line to my new fence once they've removed all panels - they currently tie a line to their fences.

I had a similar issue a few years back OP - I own my home - next door is housing association on one side and owner/occupier on the other. Fencing came down on both sides on the same night - incidently the same day as I picked my new rescue dog up (HA neighbours also have a dog) so it was super-urgent for me to get it sorted. I ended up just paying for both sides of fencing as I wanted it done that day - the HA neighbour kindly offered to pay me back half for the side between our houses (I didn't ask or expect it tbh - just wanted to let her know it was happening and when) and the owner/occupiers on the other side didn't offer me anything at all (to be fair, I think that was the 'side' that I'm meant to be responsible for). I just took the hit rather than ask for anything and would expect to again - thankfully my garden is fairly small so we're talking only 4 panels each side and it didn't cost that much at the end of the day.
