I'd say I trust my Weimaraner off leash for the most part, but I always keep an eye on him.

I have a bit of trust in my Weimaraner off leash, but I never let my guard down. They have a strong hunting drive and can get distracted easily. I’ve seen mine take off after a squirrel and it took some serious training to get him to come back. Just make sure you have a solid recall command down before you try it.
