Hello Jeremy,
Welcome aboard!

To answer your question, yes you can take him off of the wet food, dry food is enough.
Don’t feel you have to over feed them while they are younger, with the right amount of food, they will naturally grow.

If you want to make sure they get the right nutrition and a healthy meal, you may want to consider switching food.
I know marketing has made us believe that Pedigree is a healthy diet for our little buddies, but unfortunately that is not always the case.
I looked up the Pedigree nutritional facts for you and this is what I saw for the first four items listed. (Ground whole corn, Chicken by-product Meal, Rice, Corn Gluten Meal)
In case you didn’t know corn is the number one allergen for dogs and it has absolutely no nutritional value to the dog. Actually the dogs stomach has to work extra trying to break it down and get a protein source out of this. So for it to be listed twice in the top four things that consume the foods weight is not good. Think of it like this, you never hear of wolves raiding a farmers corn field, that’s because they know that is more harmful to them than beneficial.
The second problem is “Chicken by-product meal” that could be the feet, beaks, etc..probably not too much meat. You want to look for just chicken meal and not By-product.
One more thing that you want to look out for that this label has is animal fat, this is to vague. This can be rat fat, or even dog fat for all you know. You want to look far something specific like chicken fat.

You can just shop around for a good food, typically you will not find one in the supermarket. When you are looking, just try to stay away from corn, wheat and soy.

Let us know if you have any other questions.

I hope this Helps!
Chris
