My Dog Draco is coming up on a year old and I'm wondering how long did you leave your CC on Puppy food. I have read multiple recommendations for large breed dogs, 12 months, 18 months and 24 months. He's a big dog, even for the bread, so I'm not trying to put extra weight on him, just curious how others handled it. I'm interested in hearing how long you left your dog on puppy food? Also, do you wish you would have transitioned sooner or later?
