Although we found no AAFCO nutritional adequacy statements for these dog foods on the Go! website, each product appears to be designed for specific life stage.

Go! Fit and Free Adult dog food was selected to represent the other grain free dog foods in the product line.

Estimated Nutrient Content
MethodProteinFatCarbs
Guaranteed Analysis34%16%NA
Dry Matter Basis38%18%36%
Calorie Weighted Basis32%37%31%

The first two ingredients include chicken meal and turkey meal. These meals are considered meat concentrates and contain nearly 300% more protein than fresh poultry.

The third ingredient in this recipe includes salmon meal, another protein-rich meat concentrate.

We are pleased to note that, unlike many fish meals, this particular item appears1 to be ethoxyquin-free.

The next three ingredients include the following meats…

  • Chicken
  • Turkey
  • Trout

Although they’re all considered quality additions, raw meat contains about 80% water. After cooking, most of that moisture is lost, reducing the meat content to just a fraction of its original weight.

After processing, these items would probably account for a smaller part of the total content of the finished product.

The seventh ingredient includes potato. Assuming they’re whole, potatoes are a good source of digestible carbohydrates and other healthy nutrients.

The eighth ingredient mentions peas. Peas are a quality source of carbohydrates. Plus (like all legumes) they’re rich in natural fiber.

However, peas contain about 25% protein, a factor that must be considered when evaluating the total protein reported in this food.

The ninth ingredient is tapioca. Tapioca is a starchy extract made from the root of the cassava plant. This carbohydrate is not only grain-free, it’s also gluten-free.

Lentils and chickpeas are nutritious members of the legume family. They’re rich in protein and dietary fiber.

Chicken fat is obtained from rendering chicken, a process similar to making soup in which the fat itself is skimmed from the surface of the liquid.

Chicken fat is high in linoleic acid, an omega-6 fatty acid essential for life. Although it doesn’t sound very appetizing, chicken fat is actually a quality ingredient.

From here, the list goes on to include a number of other items.

But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of this product.

With four notable exceptions

First, chicory root is naturally rich in a substance called inulin, a starch-like compound made up of repeating units of carbohydrates and found in certain roots and tubers.

Not only is inulin a natural source of soluble dietary fiber, it’s also a prebiotic used to promote the growth of healthy bacteria in a dog’s digestive tract.

Next, the company appears to have applied friendly microorganisms to the surface of the kibble after cooking. These special probiotics are used to enhance a dog’s digestive and immune functions.

Thirdly, we note the inclusion of canola oil. Most applaud canola for its favorable omega-3 content while a vocal minority condemn it as an unhealthy fat.

Current thinking (ours included) finds the negative stories about canola oil more the stuff of urban legend than actual science.2

However, plant-based oils (like canola) are less biologically available to a dog than fish oil as a source of quality omega-3 fats.

And lastly, this food also contains chelated minerals, minerals that have been chemically attached to protein. This makes them easier to absorb. Chelated minerals are usually found in better dog foods.

Go! Fit and Free Grain Free Dog Food
The Bottom Line

Judging from its ingredients alone, Go! Fit and Free looks to be an above-average kibble.

In any case, it’s still important to estimate the probable amount of meat present here before determining a final rating.

The dashboard displays a dry matter protein reading of 38%, a fat level of 18% and an estimated carbohydrate content of 36%.

High protein. Above-average fat. And low carbohydrates when compared to a typical dry dog food.

In addition, even when you consider the protein-boosting effect of the legumes, this is the profile of a kibble containing a generous amount of meat.

Bottom line?

Go! Fit and Free Grain Free is a meat-based dry kibble dog food using a generous amount of named meats and meat meals as its main sources of animal protein, thus earning the brand 5 stars.

Enthusiastically recommended.

    Ruth: this is a dog-food reviewing and discussion site. The Dog Food Advisor does not produce, sell, or even advertise for any brand of dog food.

  • Ruth Conaway

    I am interested in chicken rice dog food. Do you have this?

  • Melody

    @ Brooke, you don’t actually need to feed a food specifically for large breed puppies to a German Shepherd. Just keep the protien low while growing to add to problems for a puppy possibly predisposed to hip or elbow dysplasia (which you have no way of knowing until later in life).
    You can add Glucosamine & Chondroitin supplements. I give my German Shepherds Phyto-Flex by Nature’s Farmacy.
    Unfortunately my male has elbow dysplasia despite coming from great Czech bloodlines. If you feed a high protien diet to a large breed puppy and they end up with ED or HD the breeder may try to blame you. A responsible breeder won’t. I did research & thought I had found a decent one with good
    Bloodlines, til she tried to blame me for causing a GENETIC disease. A high protien diet can exacerbate the disease but the disease has to be there to begin with, it can’t cause a genetically bases problem!!!
    Good luck!!

    In answer to Mary Varcoe’s question. Natural Balance has a grain free Bison and Sweet Potato formula. Also no carrots in it.

  • http://DogFoodAdvisor.com Mike Sagman

    Hi Mary… Unfortunately, since each dog responds to a particular food in its own unique way, I cannot provide customized product recommendations. Please visit our FAQ page and look for the topic, “Help Me Choose a Dog Food” for more information. Or check back for a possible response from one of our other readers.

  • mary varcoe

    I have a 12 yr old min schnauzer who has dealt with allergy skin problems since her she had her litter at age 3. We’ve tried hypoallergenic foods…medi-cal vegetarian…natural balance fish/sw potato… medi-cal hypoallengenic…medi-cal skin support…AND now she is on “Bison raw meat by Spring Meadows” and brown rice with NO ITCHING. She is also on a low dose of prednisone pills to alleviate the itching. I’ve tried raw chicken, salmon juice, oatmeal and beef and the itching increased. Is there any dry dog food that uses bison as a protein, grain free and carrot free since the frozen bison patties are $$$$ from Sask.(they come with no vegatables) Whatever it takes to keep away from the vet…since we’ve gone that route.

  • mary varcoe

    My 3 min schnauzers(8 yrs old) are on “Now” senior and I was wondering if “Go” kibble is larger? (They eat too quickly and then regurgitate the sm kibble) If they maintain normal weights, should an 8 yrs old dog be on senior or adult formula?(no health issues) If I were to change their food to “GO” is there still a 2-3 wks transition period with changing their diet? What is there to gain?

  • http://DogFoodAdvisor.com Mike Sagman

    Hi Julie… I’m a big fan of diet rotation and topping. Since both of these foods are rated for all life stages, they are probably appropriate for your 6 month old Aussie. As to mixing ratios, I don’t think it really matters.

  • Julie

    I just bought Go Natural Grain Free’s Dry and Canned food for my 6 month old Aussie.
    What is your opinion of mixing the canned and dry at each feeding?
    What porportions should I use?

    Hi Sophie… Protein can be a controversial topic. So, the answer depends upon whom you ask. For a better look of my personal opinion, please visit our FAQ page. Look for the topic, “Dog Food Protein”.

  • Sophie

    HI! I have a Yorkie Terrier who will be 6yrs old in May and weighs between 20-22lbs. I just started feeding him
    EVO Small Bite Dry Dog Food along with
    EVO Dog 95% Meat Chicken & Turkey Canned Dog Food. Am I giving him too much protein with this food? Should I alternate with something else?

  • http://DogFoodAdvisor.com Mike Sagman

    Hi Juliette… What is the point of gradually increasing protein? Please visit our FAQ page. Look for the topic, “Dog Food Protein”.

  • Juliette Joyce

    My Aussie(6 months) is currently on the Artemis Fresh Mix Med/Large Breed formula that has 27% protein with some grains of barley and brown rice. At 1 yr I plan to switch to the Go! Natural Grain Free Endurance which is 34% protein and grainfree. At 2 yrs begin the Artemis Maximal Dog formula with 42% protein and grainless. What is your opinion of this approach of slowly increasing the protein content using these brands?

  • IC

    [Jane] re: Allergies – My dog was licking her paws and scratching. Since this started with an ear infection before Xmas, I immediately thought yeast imbalance. I cut out all high glycemic foods; carrots, yams, sweet potatoes, peas as well as brown rice. I switch her kibble to Go Naturals, Salmon and Oatmeal Formula. Remarkable difference. Just 1.5 weeks ago, I gave my dog some carrots. Next day, scratching again.. Just two days ago, I tried brown rice again and too, scratching started. I presume my dog has possible allergies to wheat.. Rice..
    Bottom line is that the Go Natural Salmon and Oatmeal (gluten free) formula is working like a charm.
    I half cook for my dog so is why the additional foods are listed above.
    [lovelace] Re: Small bite kibble for Chihuahua.
    I haven’t tried this No Naturals Endurance Formula for my 6.5 pound Yorkie (but am planning too) as I presently feed Go Naturals Salmon and Oatmeal Formula. I find that the kibble size is acceptable although finding that some, in the mix are hard so I tend to moisten the kibble with a bit of slightly warmed water before feeding.
    We brush my dogs teeth daily so am not too concerned about the wet food factor.
    I wanted to mention however, that prior to feeding the Go Naturals Salmon Formula, we used to feed the Now (grain free) Small Breed Formula. Tiny little kibbles. Great for a toy dog! Made by the same company, Petcurean that manufactures the Go Dog Food Line.

    Although DFA rates this food as a four, it may be worth possibly checking out for your Chihuahua.

    First of all, Ed, my website review philosophy is intentionally based upon government regulated labels only. We intentionally ignore everything else. Not because these things aren’t important but because most manufacturers claims cannot be readily verified by a reviewer. I’m not willing to take the word of one factory at the exclusion of hundreds more. To be fair to my readers as well as the companies themselves, I’d have to check each and every one of them… a massive and impractical undertaking not appropriate for one lone reviewer.

    However, I can assure you that you are not correct in your assumption that only two pet food factories possess top notch certifications for manufacturing human grade foods.

    Weruva alone uses a sparkling human grade factory in Thailand and maintains all of these certifications: GMP, HACCP, BRC, EFSIS, ISO, FDA, EU, USDA, SA8000

    At this point, information like you present here for your personal favorites are more of a curiosity to me (too) and nothing more.

  • TW

    ed
    I was browsing the Weruva site the other day and they do include a section (called Safety 1st) where they list their certification claims.

  • Antonio

    Ed, actually Purina & Science Diet do feeding trials, in fact Purina pretty much set the industry standard for feeding trials.

  • ed

    Do they have ISO Certification? Natura is the only other I know of. HK is more of curiosity than a pet food company. I know a few people that have used it and stopped because the dogs lost so much weight.

  • http://DogFoodAdvisor.com Mike Sagman

    You must be including Weruva and Honest Kitchen, too

  • ed

    I will stand by my statement, RC is the only company that does real scientific feeding trials on all formulas and is one of two company where the production of dog food is on par with human food.

  • http://DogFoodAdvisor.com Mike Sagman

    Ed… Very few companies actually perform feeding trials.

  • http://dogoninn.com Kristin

    Diamond products are cheaper, yes, and also higher rated. A win, win in my book.
    But Ed is correct in that Innova puppy food costs more than RC GSD Puppy. I must have been looking at the Innova adult price, which is less than the puppy food. Innova Puppy was at PSP for $1.79 a pound whereas the RC GSD formula was $1.60 a pound. I was correct in my original statement though that Fromm Gold Large breed puppy is cheaper at $1.30 a pound.

  • ed

    Diamond, Chicken Soup and Premium Edge are cheaper than RC for a reason. RC is about $1lb, a lot less than Innova and Fromm.

    No company does actual feeding trials like RC.

  • http://dogoninn.com Kristin

    Brooke,
    You may want to check out this spreedsheet. https://spreadsheets.google.com/ccc?key=0AmNw5KB82-n_dGtyOEpVVXhPQ2tfeU1FUGdEdjVnTkE&hl=en
    Along with Kirklands (not shown on my spreadsheet yet), there are many other affordable (considerably cheaper than the 3 star rated Royal Canin) 4 and 5 star foods.
    As far as large breed puppy formulas, Diamond makes Chicken Soup, Diamond Naturals and Premium Edge.
    Natura’s Innova has a large breed puppy formula, as does Fromm Gold Nutritionals. Solid Gold’s large breed puppy formula is called WolfCub. All of the above mentioned formulas are cheaper than Royal Canin and higher rated.

  • ed

    Yes Royal Canin Large Breed Maxi for puppies or the GSD Formula. I would stop the Kirkland. I don’t have any faith in Diamond. The food elitists wont support me on RC but there is only one other company, Natura, with the same ISO Certification. Also, RC was the first to market large breed foods. They work plain and simple.

  • Brooke

    We have a new 14 wk old GSD puppy and I want to make sure she gets the best that we can afford with money being a little short. I saw that Kirkland dog food has a 4 star rating and is made by Diamond. My only concern was that they do not offer a large breed puppy food. I no that they add ingredients like glucosimine, l caritine ect. to support there large bone growth. Could you recommend either another food that offers a large breed puppy food or an aditive that I could give her along with the Kirkland dog ? Thank You

  • kevin

    i fed my puppy Taste of the wild sierra mountain formula and he poop more than 8 times daily,,,after switch to Orijen he poop less ( 2-3 times daily )…Do you know the reason? I am planning to switch him to this food ( Go natural grain-free )…..what is your suggestion?

  • http://DogFoodAdvisor.com Mike Sagman

    Hi Tyler… Hill’s claims its Prescription D/D product is for dogs with skin problems or food allergies. If you find these products unaffordable, you may wish to review or list of suggested hypoallergenic dog foods. Hope this helps.

  • Tyler

    i have a one year old Shiba-Inu that is currently on Hills perscription diet D/D. Is there another compareable food to this that is cheaper?

  • http://DogFoodAdvisor.com Mike Sagman

    Hi Brad… Whether or not to go grain free is a personal choice you’ll need to make on behalf of your dog. The idea of going grain free should have nothing to do with your dog’s activity level but rather if you need allergy control or if you’re trying to more closely mimic a dog’s natural ancestral diet. Hope this helps.

  • Brad Pankey

    I just adopted a one year old (or about one) Bull Terrier mix that weighs about 50 pounds. I plan on running with him quite a bit and I want to put him on the best food I can. Should I go Grain Free? Any specific suggestions would be great. Thanks for the help.

  • http://DogFoodAdvisor.com Mike Sagman

    Hi Mike… As far as I know there is no specific nutrient recommendation for an 18 month old Shar Pei. Just the same, it’s no secret, we shamelessly favor dog foods rich in meat. That’s because meat has a superior biological value to a dog than plant-based protein. The main benefit of grain free is these foods tend to be higher in protein, somewhat easier to digest and hypoallergenic.

    My most important suggestion is to be sure to feed your dog appropriate for his age. If he’s still growing, continue to feed a product meeting AAFCO nutrient profiles for growth (puppies).

    You may also want to read my introduction to Best Puppy Foods for a better understanding of protein content of a dog’s diet. Hope this helps.

  • Mike Fitzgerald

    I have seen Protein % as low as 17 and high as 42%. What is the correct % of protein, fats, and carbs for an eighteen month old Shar Pei?
    What is the advantage of grain free? It seems that most grain free have a higher % of protein. Good or bad. It all goes back to my first question.

    Thanks

    high quality grain free dry dog food for 2 cavaliers with allergies?? thanks

  • http://DogFoodAdvisor.com Mike Sagman

    Hi Chris… This is a common (and controversial) issue. Although many still believe dogs need less protein as they age, more recent research suggests older dogs can have difficulty absorbing protein (especially the lower quality vegetable-based types).

    Today, many canine professionals are beginning to recommend maintaining (or even increasing) dietary protein as a dog ages. The article “Senior Dogs and Special Needs” by respected nutritionist Dr. Lew Olson presents the more modern view. Hope this helps.

  • Chris Natoli

    I have an 11 year old 140lb american bulldog who has slowed down in his older stages and has no become very active anymore. Ive been feeding him the go endurance formula for a few years now. Is it still safe to have him on a higher protein diet like this or should I switch him to a senior formula (wow senior) with lower protein intake?

  • http://DogFoodAdvisor.com Mike Sagman

    Hi BJ… It would be unfair for me to pick a “best” food for your Chihuahua. There are many 3, 4 and 5-star dog foods that should be great for your dog. You’re right in asking about kibble size as this becomes important for small dogs like yours. Unfortunately, most manufacturers don’t provide that information.

  • BJ Lovelace

    I am looking for the best dry food for my 2 year old Chihuahua. What do you recommend & what size are the kibbles?
