Jasper ran out of food, so I need to ask a couple questions...

Is adult food fine for him?(He's 10 months old), also what are the pros/cons or differences of putting a dog on adult food, or keeping a dog on puppy food?

Also, I wanted to keep him on Wellness, since I like how it doesn't have corn, boxers aren't good..at all, with corn, but Im not babysitting anymore, and also paying alot soon for my school course in September.

So I need to ask which of these cheaper foods are better, ingredient/quality wise...
