It's been awhile since I have posted but I'm back with another question. Normally I feed my dog Diamond Grain Free dog food but sometimes I get caught in-between paydays and Thor runs out of food. I am looking for the best cheapest dog food to buy just for those times. It doesn't happen a lot but I want to be prepared for the next time it happens. Also, I am thinking about feeding him Dyne for the extra vitamins and minerals so when I do have to down-grade on dog food. Let me know your best suggestions and you suggestions on Dyne. By the way Thor is a full grown Pitbull.
