I don't have a Mastiff, but I do have a system to determine if what you are feeding is right. 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. Here is a link to a good illustrated guide,
I am skeptical about the value of premium foods, but likely there is nothing wrong with Royal Canine. i have seen bad reports on it, but also on every other food out there.
Easier dogs will give up their pulling with a few good snaps of the leash combined with a stern "Bad dog!". You can work up to forceful corrections with the leash doubled up in both hands and your whole body behind it. But you don't want to use any more force than you need. One gentle technique I like is to just stop when he pulls. He wants to go. If you move forward when the leash is slack, and stop when he pulls, he should quickly figure out the only way to get to go, is not to pull. This is about teaching him not to pull, not getting somewhere. The man that taught it to me said "If in a half hour you haven't made it out to the front walk, fine, you have taught him a lesson. Pulling the dog backwards is a good technique too.
Still, you may want to switch to a head collar. The leading brands are Promise, Haltie, and Gentle Leader. They have a strap going around the dogs nose looking something like a muzzle. They work by pulling the dogs head around.

100lbs is a nice, lean weight for his age. Good job!
Royal Canin is not one of the better foods. Look into foods like Wellness Large Breed Puppy, Orijen Large Breed Pup, Blue Buffalo Lg. Brd, Natural Balance, or Sold Gold Wolfcub. Check out the food forums to learn what to look for in a large breed puppy food!
You NEED to take obedience classes and learn how to properly walk your dog with a collar. Tools like the gentle leader are great, but you need to train your dog to walk properly. You don't want a 200lb dog dragging you down the street.
