Do you have dog food

Yes

Yes most of the costco stores I've been in carry dry dog food and have different varieties. They have some wet dog food as well but not a lot of varieties.

Yes. Costco has a kirkland brand of dog food. Dry and wet (canned) food. I see it's available online but you might want to call to confirm which ones are available in store.
