What kind of diet is your baby on?

His name is Bleu and he's 1 year old. I jist adaopted him yesterday. Previous owner said he's been on Pedegree adult kibble. He hasn't touched any food ive tried to give him. I've also given him a couple milk bones which he promptly takes and buries in the yard. He's extremely playful and seems happy but I know it's a new environment for him. Jist trying to help him the best I can. He's my 1st husky. Any tips are appreciated.
