There are many people who will buy a cheap bag of dog food at the dollar store in hopes of saving a little bit of money. I have tried this method and it simply doesn't work. Sure, you can get a 1 pound bag of dog food at the Dollar Tree for $1, but if you buy in bulk 50 pounds of good quality dog food would only cost you $25 anyways. In the end, you are saving money and getting a better product for your money. I have also realized that the cheap dog food doesn't go as far. You need to give your dog double the amount because of the lack of protein to even make up for it. In my opinion, it is definitely worth spending the money and getting the more expensive dog food upfront, which in the end saves you money.
