Which dog food is better?

I suggest Eukanba. However, you should ask the breeder/pet shop where you acquired your puppy from what food it has been eating. It isn't good to change food suddenly especially when they are puppies. If you want to switch, add a bit of the new food to the original food and gradually increase the new food and decrease the original food, this way your puppy should have no problem getting used to the food! :)
