Gram is a Boxer and one of The Bullies
Gram is an older dog, so he's not a pup. He tends to call the PAW Patrol "Runts". Even though he and the other bullies get what they deserved, they continued to pick on the pups. He prefers to bully Marshall, since he's so clumsy.
Gram has a pushy attitude and mostly mocks what Marshall says to him. He doesn't like to give in, but he takes his frustration out on shoes by chewing them.
Gram is a large tan boxer with a nip out of his right and left ears. He has a dirty rusty chain around his neck.
