I want to let my dog off its leash on a park trail.
Isn't there a rule about keeping dogs on leash?
My dog is a loyal super being, so I can trust him not to run off of the trail.
You should keep your dog on the leash. What happen if your dog ends up biting someone and you don't have a way to stop it.
My dog can end up biting someone?
Leash laws exist for a reason. Your dog may be well behaved, but not all dogs are and you may encounter one of those. Also, many people are afraid when unleashed dogs approach them.
