Scared my dogs will hurt next doors dog

[Alittlebitfat25]

I have four golden Labradors who are all family, as in we have the mum who is 12 and dad who is 10 and two of their puppies who are now 9 years old.

One of the puppies had an incident with a small dog when he was only a year old and was bitten on his leg during a training class and ever since then he is extremely aggressive when it comes to small dogs. When he goes out for his walk, he has a muzzle and we walk him early in the morning and late at night to avoid other dogs and of course he is on a lead so can be restrained.
Our next door neighbors moved in around a year ago and unfortunately for us have a Jack Russel who is very barky and snappy. The fence is also falling apart making it easy for the dogs to get through and it is there side of the fence as in they are responsible for it and we do not have the money to offer to replace it. Its also worth noting he is a builder so could easily install new fence panels. We have dropped multiple letters to the house, spoke to them when we have managed to catch them and basically begged them to mend the fence and warned them repeatedly what would happen if the dogs got through. It makes it worst that we have four because of obviously the pack mentality and if one started attacking they all probably would.
The obvious solution is to muzzle the aggressive one in the garden but as summer is here it doesn't feel very fair at all and it would mean muzzling all of them in this heat. Is there anything we can do to almost force them to mend the fence? I am terrified the poor little dog is going to get hurt.

But why should they? If money is tight and they don’t want to spend it on fixing their fence that’s fine, their dog isn’t the problem. It’s secured for the little dog.

if you have a dog, or four dogs you need to secure your garden. You can’t force others to pay to secure your dog(s). In your garden, she needs to find a solution she can afford and take out a loan. Or she will loose her dogs if they savage the dog next door and she has been found to not securing her garden,she will likely also be banned from owning dogs again, and her dogs maybe put to sleep. It’s not fair on the animals and she clearly knows there is a significant risk here.

she is legally responsible to control her dogs and if she can’t afford it she shouldn’t have the animals, it’s not fair on them. It’s also deeply unfair on the neighbours as she’s not just risking her own animals lives but also that if rhe little dog next door.

Op says "making it easy for the dogs get through" and uses the plural a couple of times, she also didn't correct the first few people who said it's her responsibility to secure her dogs in her own garden so, I'm sure she would have quickly pointed out her dogs weren't the ones going through fence and it was actually the Jack Russel was going into her garden.

OPs dogs have the risk of being PTS if they did indeed go through the fence and kill her neighbours dog. She could also have some expensive vets bills on her hands if they cause lifelong injuries. And because she's popped letters through the door I hope her neighbours have kept them as evidence OP knew full well the risks her aggressive dog posed to her neighbours dog and took no steps to secure them.

So you own a dangerous aggressive dog but it's up to your neighbour to sort it. Get a fence. You can afford four dogs I see.

Not all dogs will roam so perhaps the neighbours are happy their little dog will stay and don't need the fence as much.
My dog won't roam. Shes only 2 but is trained not to.
