Having owned 8 previous houses I knew that the no fence rule would not work for me so I bought a corner lot Villa. I installed two doggie doors and they go in and out all day long. My female sleeps outside for hours now that the weather is cool. They love it and are Not restricted to fresh air only during walks. Elective fences were not an option for us.
My dogs are trained to pee and poop on command. Not hard to do but many dog owners do not invest the time to train their dogs to be good citizens. Seems we have two extremes in TV. On one hand is the dog owner who has no regard for other people and on the other hand people who have zero tolerance for dogs and go balistic if your dog sniffs a bush after emptying his bladder before the walk. That is why I believe that good fences make good neighbors.
If Courtyard Villas were not available my wife and I would have not moved here. It was a deal breaker for us. We learned several houses ago about the problems that go with no fences and not just from dogs. Sure it looks nicer without fences but less aggravation with one.
I think someone needs to adopt a rescue dog
