Couldn't agree more, OP. Go nuclear; sometimes it's all anyone understands. ('Anyone' being the dog owner, not the dog of course.)
I'm all for 'live and let live'. I know some people don't like children; I don't let children in my care bother strangers. Likewise, some of us don't like dogs/are allergic to dogs/are worried about toxocariasis etc. So, sauce for goose, sauce for gander: dog owners: prevent your dogs from bothering people - especially small children - that you don't know for sure will welcome such bothering, and make sure you clear up all their mess. 'Prevent' there is an active verb, note: either train your animals to never bother other people (difficult perhaps, but maybe possible), or keep them tied up on a lead and close enough to you that you can stop them whenever there's a possibility of other people - especially small children - being around. And don't leave their faeces around on the ground in public places like parks.
One recent experience. Recently in the local park, which is generally full of animals running round, but which has a (very) small fenced-off playpark with the usual 'no dogs allowed' sign on the gate. And - you guessed it - a man with a small child and a dog inside the playpark. When I pointed out (my DGD, 18months, is properly scared of dogs) that the dog shouldn't be there, I got a stream of abuse, 'Huh, always some jobsworth, etc., etc. ...'
Now, if you want to take the risk of disease (see, eg www.dailymail.co.uk/health/article-2242751/Girl-nearly-goes-blind-inadvertently-eating-parasite-dog-mess-travelled-stomach-EYEBALL.html) or attack on your children by your animal, fine; your decision. But it's plain not fair for you to put those risks on other people's children.
In short, keep your dogs away from me and my family! It's your responsibility, note, not your dog's. Otherwise, take the consequences: any dog getting too close to me or any child under my protection can expect to be forcibly moved away - force applied being the minimum required, sure, but up to fatal if necessary.
I've tried being reasonable. Many dog owners don't seem to get it, though. Talk, reasoning, doesn't work. So, seems it's the only way. And I recommend it to others, including the OP. If enough of us do this, the dog-owning miscreants will soon catch on.
If you're a properly responsible dog owner, you'll have no quarrel with any of this: you won't allow your dog near me or my family, so there'll be no trouble. If you're irresponsible like Mr 'always-a-jobsworth', expect trouble. 'Nuclear' trouble, if necessary!
