Everything you just said is just lazy selfish BS...
I'm sorry, but I do not want random dogs in my yard. I am also sorry if when I am walking my dog on a leash- your little friend feels it may be a good idea to run out into the road to greet me and my dog if my dog wants no part of it.
I'm also sorry that when I am walking on a mountain trail, I do not want your dog with you no where in site running up at me because the last 3 that did so were also snipping at my heals.
I'm sorry you cannot afford a fence to allow your dog to do these things without bother, I am sorry I have a young child that is allergic and your friendly dog wants to come up into our private space to say hello.
The old days- back in the 70's, 80's- we all had dogs, no fences and did not always know where they were playing. We also had so many less homes, we had kids and families who all knew each other and their pets and we all played with them. If there was a bad dog- my dad would stop at your door and tell you straight up to keep control of your dog. And so many dogs were treated not as family but as, they are there, they will eat when hungry and they will come home when they are too hot or cold.
This is not life in 2022...houses are on top of each other, your dog does not always know my family or does my family know you or your dog.
And, many of us treat our dogs as loved family.
What would you say if your dog decides to come onto my property with my dogs that has an electric fence and my dog hurts him/her, when they do so?.
sorry, imo you're the one with the selfish lazy BS.
you can afford a yd and an electric fence, but many can't.
and many work and can't walk the dog every time it has to go, or can't walk it all the time in all weather for other reasons, but still would love to have a dog.
and while you think your dog is might be happy in that small fenced in yd, i assure you they'd be 50 time happier if they could run the neighborhood. (and nobody's i knew ever strayed far from home much).
your dogs are only territorial now because of your fence, and aren't used to others from growing up in a non fenced/leashed world..
put a dog on a leash or confined to a small space, and it instantly becomes territorial even when it otherwise wouldn't be.
that said, obviously in very high density neighborhoods with large apt/condo MDU buildings, it's not going to work, but in single dwelling neighborhoods it worked fine.
and i find that almost all i talk to regarding this subject who are opposed to small medium dogs running, never lived back when small and medium dogs could run in single family neighborhoods, and leash laws for all is all they've ever known.
those who lived back when small/medium non aggressive breeds could run single family neighborhoods, miss those days and think it was better then, for both owner and dog.
another thing to realize, is back when small/medium dogs could run, they all grew up around other people and other dogs, so were used to being around strangers.
the leash and the fence are what created smaller/medium dogs needing to defend their turf, because running is no longer an option, and they are no longer used to being around other people and dogs.
btw, what type dogs do you own?
