RE: I Am Alive And I Have A Companion To Run Errands With :)

Legally, no, you have to walk on leash here. There are plenty of people who ignore that law, but you can be fined a couple hundred dollars for doing that. If there is a fenced in place, you can be off lead - someone who has a yard, or a specific dog park that has fences.
Especially since being hit by a car is how he lost the leg in the first place, I definitely don't want to be off lead near cars with him. Sometimes he is afraid of cars, such as on the busy road, but other times he sees another dog across the street and wants to run to them without paying attention. I'm trying to teach him to always stop at the road and wait until I say the word "cross" to go across it.
