I don't ever walk the streets around my home now, for the fear of a dog not being on it's LEASH!
My life has had to change, for that very point.
Yes...dogs should be at all times on a leash.Dog signs are there for a reason, so I say dog owners need to comply.
I comply, as there are enough places I can take my dog that allow off leash play. While leash restrictions may irritate some dog owners that "know" their pets, this is a case of protecting the common good. As much as I love my dog, I don't want my kids around unknown unleashed dogs in public spaces.
