I often walk with my kids in the neighborhood. Time to time, there is a medium size dog without a leash outside of a house barking at us. The dog clearly belongs to the house. It looks maintained and has a collar. And I see the door opened to the backyard. Every time this happens, I turn back and use another way. I don’t want to kill the dog in case it runs towards my children. It’s not a super big deal to turn around, but it’s a bit annoying, and someone else can trigger it at some point.

Is it allowed by city rules to let a dog without a leash on the front yard? Am I overreacting?
