I am wondering about how much protein does my puppy needs other than giving him dog food (kibbles), what kind of other food do I have to give him? Thank you in advance!
If your pup is on kibble, it is a complete food and they don't need anything else. If you want to feed other foods as well, that is when is becomes rather a juggling act as you would have to reduce the kibble, unless you want to switch over to a raw diet fully.
Labs are mostly always hungry!! Seriously though, as long as he is growing well and you are feeding a good quality feed he should be ok. There are various food comparison sites so you can check it is good quality and not just full of fillers. Have a google.
Just another thought how old is he ? You might need to feed him more often than twice a day. I didn't move to twice a day until over 6 months, I fed 3 times a day before then.
