I agree with you OP. I hate it. (To be clear: I don't hate dogs...just the fact that they seem to be allowed everywhere and many owners are very selfish and disrespectful.) It is not any dog's fault.
I am disabled and either use a wheelchair or walking aids, it is very obvious that I struggle to walk. I've had to stop going to our local park where dogs are supposed to be walked on leads (prominent signs saying so) as owners ignore them, let their dogs off the lead and they let them approach, run around my feet and cause issues. Three times we've got into verbal alterations with rude owners who seem to have a problem with this, despite the fact I am obviously struggling. The last time, it was an off lead dog that ran up behind and bashed into me, nearly knocking me off my feet. The owner didn't care.
People used to care about being respectful but now, even with clear rules, they don't care- they have no idea what it's like to struggle to walk or move or how disconcerting and upsetting it is when you're trying to navigate moving around a dog you don't want near your feet.
This is just one example. The only thing we asked the owners to do was to call their dog back and keep them away from my feet... each time we got a torrent of abuse back.
People are so entitled about their dogs.
Because of it happening so frequently, I can no longer go out with my children alone, in case they can't manage the dogs that come up or in case I do indeed get knocked down. I've, in essence, become a bit of a hermit because the only place close enough to walk to is full of entitled owners who think their dogs are more important than other people's needs. If I haven't got my partner with me or a friend who is confident enough to manage dogs and deal with rude owners, I can't go.
A bit off topic from the OP but the way people are about their dogs now has made my life so much worse but I really hate just how pervasive it has become in the last few years. We won't eat in establishments that allow dogs inside and we often choose to go to places that dogs can't go to because we can't trust the owners.
I really wish something could be done about it.
