Mack is a big, friendly boy. He can pull a bit on the leash when he first comes out of his kennel, but calms down into a nice walking companion once he gets on the trail. He likes to spend his walks sniffing thoroughly and exploring. Mack also likes to snuffle around the off-leash runs. Mackis attentive and likes to keep an eye on what's happening around him. When he's in the off-leash run, he pokes his nose through the fence to see which people and dogs are on the other side. He is a smart boy and took to the agility course his first time out! Mack occasionally attends play group, but prefers to be in smaller groups with females. He isn't as much a fan of other male dogs.
