The more I read the more confused I am getting! INFORMATION OVERLOAD!

MY big question is... I am bringing a brother and sister home to raise and currently they have them on "Royal Canin" puppy food for Bulldogs. OK so I "Thought" that was a good food

in the beginning, but NOW finding out it is not.
Then started on my journey of looking at other options when I bring them home in June. READING AND READING AND READING
Kibble vs Raw vs Wet???
Can you do Kibble with some Raw?
I was really set on using the Taste of the Wild brand but now I am even second guessing that!
I just don't over spend on food, but not spend enough. I don't want to sound cheap either.
Are their other tips and tricks that we can use with kibble. I read some give a little yogurt once in a while, some apple cider vinegar in their water, and some other things that have me thinking I could try to add to their benefit and well being.
