Is ok to feed a 7 month pup whit Royal Cannin Maxi.The label ans the web tell us to start feeding afther 15 month.Any recomendations

I use Royal Canin and leave my puppy on large breed until one year.

It is OK to do that but not recommended.

Maxi Babydog should be fed until 5 months of age...
Maxi Puppy should be fed until 15 months of age....
Maxi Aduld 15 months too 5 years.
And our Labrador formula 15 months +

Would their be problems doing it and if so what? I know it is not recommended, but no one has ever said what it would do if you chose that route. The MAXI baby dog is hard to find, crazy expensive and comes in too small a bag for a large puppy. For this reason our puppies go home at 8 weeks on MAXI large breed puppy. Feed to 15 mos and then labrador.
