I will promise you this. No matter how well trained your pet is off leash if they see something which sets them off such as a cat,squirrel or another dog, at one point they will bolt.

The only exception I have seen to this are professionally trained k-9’s and those animals are actually constantly in training by their handlers so as to re enforce what they have previously learned.

My strong advice is to NEVER take your dogs out without a leash unless they are in a securely fenced area.

I agree. Besides, what's the point of letting a dog go off the leash? Is it to show of one's superb dog-training skills?

About 15,000 dog bite incidents a year by police K9's against officers or bystanders and a little under 200 incidents of a lost K9 officer indicates that even your exception isn't one. A dog off a leash can bolt or attack anyone, no matter how well trained. The difference training will make is if they come back to your side after they spit the person or creature out. Keep your dogs on leashes.
