Hi Udi W,
There is no such thing as “neuter dog food”! It’s disappointing that your vet is trying to sell you on Royal Canin. 🙁 I’m not a personal fan of TOTW, but I dislike Royal Canin more. If you search on this forum there are a lot of discussions and recommended foods for feeding a large breed puppy to prevent joint/bone disorders. You could pick a food recommended from that list. The one thing you are going to have to watch is the calorie intake as you don’t want your puppy to grow too fast and I would definitely suggest feeding 2 meals per day as opposed to one.
Red has given you some good suggestions. I have/had labs myself. My current ones are over 10 and somewhere in the 5-7ish range, male & female, both altered. I’ve never fed a “neuter dog food” and they are both in excellent shape because I watch the calories and they get lots of walks.
