I walk happy off leash all the time, but the only loose dog I have met is a black toy poodle a few blocks away the guy just lets th edog out and go's inside, I walk happy off leash liek I said, but as soon as I get near that house I leash happy and cross the street, the dog tried to come over on th eother side of the street before, but I kept saying "no, stay there doggie, stay there" and he backed back on to the sidewalk and I had a frind with a toy poodle named buffy, they did not have a yard so they just let buffy out front, right near a busy street, but the thing it, she never went anywhere she stayed on her front yard although it still sared the bejeebies out of me everytime they let her out like that. otherewise we dont have problems like, that, we have no dogparks to run out dogs in, so everyones dogs are well trained, so they can run there dogs without problems
