Here at From the Heart Rescue, we feed a consistent diet of ProPlan Shredded Chicken Blend. But, if you want to change to another brand, there are a few things you should know.
Only buy quality dog food -- it's really your choice, and what you new dog will eat. Sometimes in the beginning it might be trial and error so perhaps small bags to start with until you find the right one that your dog will eat.
Remember, though, when changing a dog's food you might get some intestinal upset. In order to avoid this, mix their current food 50/50 with the new food, then slowing wean down on the "old" food.
We may not be able to narrow down what quality food is best for your new dog but we can certainly tell you what foods NOT TO FEED your dog. Do not feed brands such as Old Roy, Beniful, Alpo and Dog Chow. These low-grade foods are over processed, filled with fillers like corn, preservatives and toxins which are very problematic for many dogs.
If you have questions about the food you are thinking of feeding your dog, you can always check Dog Food Advisor or with your veterinarian for advice.
