Crude Protein: minimum of 24.0%

Crude Fiber: maximum of 4.0%
Moisture: maximum of 10.0%

Price per pound when buying the largest bag (30 lbs at $49.99): $1.6663
Estimated cost of feeding Ebon per year on this food: $628.89 (12.58 of the 25 lb bags)
Ebon receives slightly less than the calculated feeding amount to allow for his daily treats
Ebon's overall health on this food: Not good. Though his energy level didn't change, he became itchy, vomited once, and also had rather soft stools and a very bad bout of diarrhea the day I finally took him off of the food.

I started transitioning from Ebon's old food on May 8th, took him off of the Merrick on the 11th, put him on a bland diet for a day, put him back on it on the 12th and I took him off of it completely after his incident on May 16th. He was on a bland diet with a dash of pumpkin for two days before I began transitioning him from that onto Simply Nourish as I know he is stable and does well on it and I've been using it to transition between foods during all of these food trials. He has not had a repeat incident since the one on the 16th.

The kibble. Broad picture so you can see the "Elements"
The kibble itself is rather moderate to small in size and includes these colored "Elements" that are high in calcium (egg shell meal?), chlorophyll (alfalfa nutrient concentrate?), and lutein and beta-carotene (dried carrot?). These are a bit like the LifeSource Bits in Blue Buffalo foods in that they are an attempt to prevent the damage to nutrients that occurs during the cooking process. The food smells like a typical kibble, though perhaps a bit oily.

Ebon did extremely poorly on this food, and looking at his reactions and how quickly the symptoms went away once I took him off of it, I suspect that he had an allergic reaction to something in it. The itching, the intensification of his reaction the longer he was on it, especially after I removed and then re-introduced the food. At the end of these food trials I will be doing a complete comparison of ingredients between the foods he has eaten and see if I can figure out what this ingredient could possibly be. Some things currently stand out, including the marigold, parsley, and fennel which have not been in any of the foods I have recorded thus far on this blog. This is also the only food that contains cobalt, however I doubt this is relevant. Also, interestingly enough, it shares some ingredients with foods that he hasn't done as well on, including two of the probiotics (L. plantarum and L. casei, which are in both Wellness and Taste of the Wild). Of all of these, I am most surprised to see marigold in this food. Thus far, this is the only food I have heard of that includes such an ingredient.

Though I suspect an allergy, I really do not know what happened. This is why after I took him off of the food, I cleaned and sanitized every single thing that the food came in contact with in case it had something to do with a bacterium or other element on or in the food. I am not a vet, but it is suspicious that his digestion was basically back to normal as soon as I removed the food. It's true that I switched him to a bland diet immediately (rice and ground beef drained and rinsed of fat, pumpkin added for the second round), but even then such a switch usually takes a couple of days to work. Here, after he removed the food from his system he seemed to be perfectly fine.

Since Ebon was on this food for such a short period of time, I am hesitant to make any major conclusions about my opinion of the food. On its surface, it seems to be a pretty good kibble. It fits a lot of the things I like to see in kibble, such as named ingredient sources, prominent featuring of meat ingredients, inclusion of probiotics, and chelated minerals. However, the number and location of the grains on the ingredient list make it clear this food is grain-based. I did some searching around for other opinions on Merrick's foods and I have found a lot of positive reviews as well as a lot of negative ones. Overall, I give this food a hearty...meh. It clearly didn't work for Ebon, but it's quite possible other dogs could do perfectly well on it.

Will I change foods? We'll see. Next up: Blue Buffalo Wilderness.


  1. You didn't even specify what happened with your dog while on this food. Totally useless.

    1. Uhm the author did...and I quote:

      "Though his energy level didn't change, he became itchy, vomited once, and also had rather soft stools and a very bad bout of diarrhea the day I finally took him off of the food."

      My dog had similar symptoms and terrible gas...switching to Halo.

  2. Merrick dog food is yet another dog food that hides MSG (Monosodium Glutamate) under the words ‘natural’ on the ingredients label. “Natural Chicken Flavor” contains MSG, but neither Merrick—nor any other human or dog food company—has to admit it has MSG because: The US Food and Drug Administration (FDA) only requires companies to admit MSG is there is 99% or more MSG in the additive. So, 98% MSG can be hidden under “natural flavors”. And remember: arsenic and human feces are ‘natural’ so the word ‘natural’ on any label should be a clue the manufacturer is hiding something. (A human food example is the word ‘broth’ on tuna fish cans: broth contains MSG).

    Everyone has heard about headaches as a result of ingesting MSG, but it turns out MSG is far more dangerous than just the occasional headache. Glutamate has a central role in obesity, heart disease, cancer, autism, neurodegenerative diseases, infertility, diabetes, depression and other mood & learning disorders—all of which have reached epidemic proportions. To see an interview with Dr Russell Blaylock, MD (neurosurgeon, retired) about the devastating effects of MSG, go here:

    Disguised names for MSG include: Flavors, natural flavors, seasonings, broth, amino acids, glutamic acid, yeast extract, gelatin, Anything ‘hydrolyzed’, hydrolyzed protein, ‘anything’ protein (ex. tomato/pea/etc protein), Calcium caseinate, Sodium caseinate, yeast food, yeast nutrient , autolyzed yeast, spices, gelatin, barley malt, maltodextrin, textured protein, soy sauce, soy protein, soy protein concentrate, soy protein isolate, whey protein, whey protein concentrate/isolate, stock, chicken flavoring, bouillon, broth, carageenan, tapioca starch extract, condensed milk, powdered milk, enzymes.

    Do you really want your dog eating something Merrick hides to trick your dog into eating more than they otherwise would (which is what MSG does), making your dog obese and sick? Write or call Merrick and tell them you are on to their tricks. And find another dog food brand to buy that doesn’t have any of the trick words above. Vote with your pocketbook. And protect yourself and your pets from this toxic stuff.
