The little doggie was living his life in the street, homeless. He was on the loose, so he was roaming as he pleased. How did he end up in the street we may never know and if he had an owner he's never been looking for him.
ATIS is really timid. You can tell he's hankering after love and care, but he can't quite manage to find the courage to get close to humans. There is just one person at the shelter who he dares to cuddle up with. You can see in his shining eyes how much he'd love to get close to people, but probably due to his earlier bad experiences he'd rather keep his distance. He lives free in a big yard at the shelter and he's friendly with his dog mates.
