It would not be a problem switching him to adult food at this age. Some people never feed their dogs puppy food.
If I remember correctly, Puppy Chow is a grocery store brand? None of these "name brand" dog foods are good for your dogs. They are filled with fillers that give absolutely no nutritional value.
I would check out the dog food sticky in this section and find some of the top quality foods that are in your area. Some of them are even sold at petco/petsmart. Putting him on a higher grade food will definitly help with the runs and should help start adding weight
