Huey had a similar adventure recently. Apparently the gate wasn't shut all the way and he pushed it open (probably to his great surprise!) I was actually asleep and my very nice neighbor came and told me Huey was running up and down the street and he followed her home and he ran right in the front door. He was panting and had the biggest smile on his face, then he kept crying like he was asking to go out there again! Crazy huskies.
Glad to hear yours made it back home safely too!!
