I buy natural food off of the internet... it sounds expensive but if you buy in bulk and have it shipped on a regular basis (say every 6 months) it can be less expensive than going to the store every few weeks. I posted a journal recently where I found out they put experimental lab animals in regular pet foods when they are finished experimenting with them. Go read it and see if the ingredients are in your pet food... I was so disgusted.
Choose a food that your dog will enjoy. Go for a food that the 1st ingrediant is a meat source. everything is just a filler. We use Hills Science Diet Light, I get it for a HUGE discount, otherwise I would be feeding Beneful brand to our dog.
