Grading Dog Food
This
method of grading dog food was developed by Sarah Irick. It is not to be
considered exact science but a starting point for people who need help
with how to read labels and choose a good food. You can
read about
Sarah here. She has provided, with permission to Naper
Doodles to include on our website, the
Grading Scheme,
foods that have already been graded in
Alphabetical
Order, and dog foods that have been graded
In Order of Score.
How
to grade your dog's food
Start with a grade of 100 points
1) For every listing of "by-product", subtract 10 points
2) For every non-specific animal source ("meat" or "poultry", meat, meal
or fat) reference, subtract 10 points
3) If the food contains BHA, BHT, or ethoxyquin, subtract 10 points
4) For every grain "mill run" or non-specific grain source subtract 5
points
5) If the same grain ingredient is used 2 or more times in the first
five ingredients (i.e. "ground brown rice", "brewer's rice", "rice
flour" are all the same grain), subtract 5 points
6) If the protein sources are not meat meal and there are less than 2
meats in the top 3 ingredients, subtract 3 points
7) If it contains any artificial colorants, subtract 3 points
8 ) If it contains ground corn or whole grain corn, subtract 3 points
9) If corn is listed in the top 5 ingredients, subtract 2 more points
10) If the food contains any animal fat other than fish oil, subtract 2
points
11) If lamb is the only animal protein source (unless your dog is
allergic to other protein sources), subtract 2 points
12) If it contains soy or soybeans, subtract 2 points
13) If it contains wheat (unless you know that your dog isn't allergic
to wheat), subtract 2 points
14) If it contains beef (unless you know that your dog isn't allergic to
beef), subtract 1 point
15) If it contains salt, subtract 1 point
Extra Credit:
1) If any of the meat sources are organic, add 5 points
2) If the food is endorsed by any major breed group or nutritionist, add
5 points
3) If the food is baked not extruded, add 5 points
4) If the food contains probiotics, add 3 points
5) If the food contains fruit, add 3 points
6) If the food contains vegetables (NOT corn or other grains), add 3
points
7) If the animal sources are hormone-free and antibiotic-free, add 2
points
8) If the food contains barley, add 2 points
9) If the food contains flax seed oil (not just the seeds), add 2 points
10) If the food contains oats or oatmeal, add 1 point
11) If the food contains sunflower oil, add 1 point
12) For every different specific animal protein source (other than the
first one; count "chicken" and "chicken meal" as only one protein
source, but "chicken" and "fish" as 2 different sources), add 1 point
13) If it contains glucosamine and chondroitin, add 1 point
14) If the vegetables have been tested for pesticides and are
pesticide-free, add 1 point
94-100+ = A
86-93 = B
78-85 = C
70-77 = D
69 = F

About the Author of this Food Grading Method:
My name is Sarah Irick and I
am a Great Dane owner and rescue volunteer. I am a Civil/Industrial
Engineer, not a veterinarian or animal nutritionist by education or
employment. I do not work for a pet food manufacturer nor am I
affiliated with one. I am just an individual who is concerned about what
I feed my dogs and wants to help others decide what to feed their own. I
cannot remember the exact date I designed this system, though I know
it's been more than a year (probably 2-3 years ago). I was concerned
with the way people sometimes throw out names of "good" dog foods that
maybe aren't so good, and others take their words for it. Foods that
maybe used to be good before their ingredients were changed for the
worse or before better options became available are still being touted
by some as being super-premium and I disagree. Since many pet owners do
not have the time or inclination to do as many hours of research into
pet (specifically dog) nutrition as I and many of you have, I wanted an
*easier* way for them to compare labels. Unfortunately it is still a bit
cumbersome (sometimes 2 people calculate the same food and get different
scores even) but it's better than nothing in my opinion.
Is it exact science? No. I
don't claim for it to be. In fact I’ve had to make a couple of changes
over time (which the above don't reflect) for new circumstances I’ve run
across, such as the food that contained NO MEAT (not a special diet just
one that was so cheap it didn't contain any meat at all) and needs a
steep penalty in my opinion, but still scored a decent grade on the original.
Another example is the
newer kibbles that contain no grain but, in my opinion, if it still has sufficient
fiber and carbs then it deserves extra credit that wasn't previously
reflected. Also I’ve gotten comments and opinions that I take seriously
and incorporate if it seems appropriate.
I don't have a permanent site
host for this although seeing how hugely popular it is and how widely
spread without accreditation it has become perhaps I should do so. It
isn't that I care so much about credit but many people will ask the
questions that your posters have about my affiliations and biases, etc.
I don't officially support
any one food; anywhere that I personally posted grades on specific foods
it was to give an idea of where these foods fell so people didn't always
have to do the math. If you want to e-mail me with questions or
comments, you can at
fredirick@hotmail.com . This is my "spam" address,
so put "Dog Food Grading" in the subject line or I'll probably delete it
mistakenly. ~ Sarah Irick
