Zero is still learning to trust, but he’s made progress since passing his temperament test with another dog. Around new people and animals, Zero can be timid at first, but he doesn’t show aggression. He does have barrier aggression, so introductions are best outside, away from kennel doors. There are hints that Zero once worked as a guard dog, which comes through in protective behavior behind fences. Get him out in the yard, though, and he softens up, showing a gentle and sweet side that just needs a bit of patience to shine through. He is not yet house trained. If you’re willing to give him the chance to decompress in a calmer setting, Zero could make a loyal companion. Ready to meet your new best friend? Apply now!
