Hi,
Im a new puppy owner and im feeding my husky pup Aeden Grange puppy food.  It seemd to be upsetting his tummy but only sometimes, how can I be sure its the food that's causing the problem? The vet said he is a picture of health but im worried.
Thanx

What was he fed by the breeder, best to continue with that till they are settled in as change of home and water can cause upset.

Change food over slowly taking at least a week if not more.

Over feeding can also cause upset, puppies don't have a "full button" and will finish everything in front of them.
