My skinny golden retriever puppy

Question
I had a 5 weeks female golden retriever and she is different with other cases since she ate a lot and at least three times per day. She is about 10kg weights and she only eat dog foods. Can i give her something other than the dog food such as chicken or any other things else? Hoping for the responses, thanks!

Answer
In most cases, the best thing is more dog food if the puppy will eat it.  Most puppies are too fat.  Unless you can see her ribs, she doesn't need to be fatter.  You should be feeding a puppy chow now. Switching to an adult chow for the larger breeds at 4 months, slows growth and helps develop sturdier joints.

Your dog definitely should be narrower at the waist than the hips and chest. You should be able to easily feel the ribs, but not see them. Each dog is different. Standard recommendations are a good place to start, but each dog must have its food and exercise adjusted to its individual needs.
