sunseeker, that sounds like one of those horrible situations, where the person who is clearly 'wrong', takes the moral highground, and then shouts and becomes abusive if challenged. Leaves you feeling rotten, well it does me.
I have two dogs currently, but have often had as many as 3. I would never let them off lead near the car park at the end of our walks, or near any road. I had a very unpleasant disagreement with a man who has set himself up as a dog walker/day minder, and is using our local park to exercise them. He usually has 5, different dogs on each of his outings during the morning, and late afternoon. He parks over the entrance we all use, opens his van door, and all 5 assorted dogs race out. As they aren't his own dogs, and only know each other on occasional walks, they are an out of control pack of dogs. His dogs regularly chase up to other dogs, surrounding them. Luckily, they seem to be generally not an aggressive pack, but all it takes is one dog to take offence as being so surrounded, and no doubt a serious fight would break out.
His dogs have surrounded my two, both of mine on leads, on the car park. I asked him if he'd call them, he shouted, they aren't doing anything. I asked again, said my young dog is fear aggressive on his lead, and may well snap. If he snaps, my big dog will wade in and we'll have trouble. He said aggressively, that he didn't need a lecture, walked off, leaving his dogs harrassing mine. Luckily, my dogs behaved well, and jumped into the car with no problems. He is a menace to responsible dog owners. The local dog warden says as his dogs haven't attacked me, or bitten my dogs, they can do nothing.
It was my understanding that one handler can now only exercise 4 dogs. It used to be 6, according to our local dog trainers at Guide Dogs for the Blind. The dog warden said this is up to individual councils. I find this worrying. There is a growing dislike of dogs amongst some people, and situations like the one Sunseeker talks about, and the fool I've described, can only add to the fear and dislike of dogs. Dogs need to run free, but shouldn't be allowed off leads near roads, children's play grounds etc. Responsible dog owners clean up after their dogs as well. Bad owners don't!
