Darford's Zero/G dry dog food gets a 5-star rating on DogFoodAdvisor.com
The following recipes were submitted for review:
Darford Zero/G Turkey and Chicken
Darford Zero/G Sardine, Whitefish and Mysis Shrimp
Here's the results from DogFoodAdvisor.com
"ZeroG is an above-average protein. Near-average fat. And below-average carbs when compared to a typical dry dog food. In addition, even when you consider the protein-boosting effect of the lentils and peas, this looks like the profile of a kibble containing a notable amount of meat."
"The recipe's use of legumes in place of grain or potatoes make this recipe a potential candidate for those looking for a kibble with a relatively lower glycemic index."
"Bottom line? Darford's ZeroG Dog Food is a legume-based dry kibble using a notable amount of chicken and turkey as its main sources of animal protein, thus earning the brand 5 stars."
I hope that helps...
