7 weeks male puppy doesn't like kibble(royal canin?

It's completely ok if your dog isn't eating dry food. Try for some other one. You can feed your dog biscuits and milk. You know the good thing about dogs is they can eat almost anything. Or you can bring some canned products. They aren't dry. Don't stick your dog to a single food. Dogs are real foodies, and they can't resist eating treats. So don't panic about diet; just give him something healthy and delicious.
