The first ingredient in this dog food is chicken. Chicken is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of chicken”.1

Chicken is naturally rich in the ten essential amino acids required by a dog to sustain life.

The second ingredient is water, which adds nothing but moisture to this food. Water is a routine finding in most canned dog foods.

The third ingredient is brown rice, a complex carbohydrate that (once cooked) can be fairly easy to digest. However, aside from its natural energy content, rice is of only modest nutritional value to a dog.

The fourth ingredient is chicken liver. This is an organ meat sourced from a named animal and thus considered a beneficial component.

The fifth ingredient includes carrots. Carrots are rich in beta-carotene, minerals and dietary fiber.

The sixth ingredient is potato. Potatoes can be considered a gluten-free source of digestible carbohydrates. Yet with the exception of perhaps their caloric content, potatoes are of only modest nutritional value to a dog.

The seventh ingredient is apple, a nutrient-rich fruit that’s also high in fiber.

The eighth ingredient is guar gum, a gelling or thickening agent found in many wet pet foods. Refined from dehusked guar beans, guar gum can add a notable amount of dietary fiber to any product.

The ninth ingredient is flaxseed meal, one of the best plant sources of healthy omega-3 fatty acids. Flax seeds are also rich in soluble fiber.

However, flaxseed contains about 19% protein, a factor that must be considered when judging the actual meat content of this dog food.

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 two notable exceptions

First, garlic can be a controversial item. Although many favor the ingredient for its claimed health benefits, garlic has been linked to Heinz body anemia in dogs.2

So, one must weigh the potential benefits of feeding garlic against its proven tendency to cause subclinical damage to the red blood cells of the animal.

And lastly, this food 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.

Castor and Pollux
Organix Canned Dog Food
The Bottom Line

Since this recipe contains a number of organic ingredients, we feel compelled to grant this line a more favorable status as we consider its final rating.

That’s because organic ingredients must comply with notably more stringent government standards — standards which significantly restrict the use of any synthetic pesticides, herbicides, insecticides, hormones or antibiotics.

With that in mind…

Judging by its ingredients alone, Castor and Pollux Organix canned dog food looks like an above-average wet product.

But ingredient quality by itself cannot tell the whole story. We still need to estimate the product’s meat content before determining a final rating.

The dashboard displays a dry matter protein reading of 34%, a fat level of 30% and estimated carbohydrates of about 28%.

As a group, the brand features an average protein content of 34% and a mean fat level of 28%. Together, these figures suggest a carbohydrate content of 30% for the overall product line.

And a fat-to-protein ratio of about 83%.

Below-average protein. Above-average fat. And above-average carbs when compared to a typical wet dog food.

When you consider the protein-boosting effect of the flaxseed meal, this looks like the profile of a wet product containing a moderate amount of meat.

Yet because of the organic nature of its ingredients and the lack of any critical Red Flag items, this dog food is entitled to an upgrade to our next category.

Bottom line?

Castor and Pollux Organix is a meat-based canned dog food using a moderate amount of chicken or turkey as its main sources of animal protein, thus earning the brand 4 stars.

Highly recommended.

However, with 53% of the total calories in our example coming from fat versus just 25% from protein, some recipes may not be suitable for every animal. In addition, this same finding also prevents us from awarding the brand a higher rating.

Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content and (when appropriate) their fat-to-protein ratios.

    I don’t understand your question. I am neither dumb or proud.

    All I know is that I fed my dog the Castor & Pollux canned dog food, she had diarrhea for three days, would not eat, and when the diarrhea turned bloody, I took her to the vet. The diagnosis was colitis and the bill was $384.

    When contacted, Castor & Pollux did not seem to care.

  • Michael Lynn

    “The label on their dog food says the food
    is backed by their 100% satisfaction guarantee, and to contact them if you are not completely satisfied. Poisoning my dog and a $383 vet bill does not constitute
    my satisfaction,… ”

    Are you trying to play dumb here or is this really what this proud generation is come too?

    I recently bought some Castor & Pollux “Natural Ultramix” canned dog food at PetSmart. Natural Castor & Pollux is owned by Merrick Pet Care. It costs $3.00 a can.

    There was no change in her diet except for a small portion introducing her to the Ultramix.

    My dog had diarrhea for the next three days. The third day the diarrhea was bloody, so I rushed her to the vet.
    After a full exam and numerous tests, my vet could not
    find anything wrong with my dog except for colitis, and suspected the Natural Ultramix was the likely cause. The bill was $383.

    Colitis is an inflammation of the colon. Viruses and bacteria can cause colon infections. Most are food-borne illnesses or “food
    poisoning.” Common bacterial causes include Shigella, E Coli, Salmonella and Campylobacter.

    I contacted Castor & Pollux who asked for a copy of the vet bill.
    Then they asked for the Medical Notes. I had my vet fax that to them.
    After two weeks, they requested my dog’s medical history. Again, my vet obliged and faxed it to them.

    Finally they called and said their vet agreed my dog had a reaction to their food, so “out of good faith,” they would send me some of the same dog food.

    Why would I want more of the same food that poisoned my dog? I declined their offer and asked they help with at least half of the vet

    Another week passed before they left a voicemail again admitting my dog had a “dietary intolerance to their food,” but weren’t going to do anything about it because their vet said their food was fine. How does their vet know? Is he/she on the manufacturing line?

    If the food was fine, why did my dog have diarrhea for three days after eating it?

    Where is the warning on the can’s label that the dog food may cause severe diarrhea, and possible death if not treated?
    I asked to speak to a manager, but she wasn’t available and did not return my call.

    Clearly, Castor & Pollux, which is owned by Merrick Pet Care Inc., does not care about the quality or safety of their food, nor will they stand behind their product. The label on their dog food says the food
    is backed by their 100% satisfaction guarantee, and to contact them if you are not completely satisfied.

    Poisoning my dog and a $383 vet bill does not constitute
    my satisfaction, and contacting them obviously does not matter either.

    Be warned.

    My little 2 yr old Maltie knew they had changed their canned turkey dog food immediately. He refused to eat it. Why do they do that? Do they really think dogs are dumb and cannot tell something is different. grrrrrrrr :(

  • Betsy Greer

    Thank goodness he’s with you now and is definitely eating so much better! I was a bigger fan of C&P before they were acquired by Merrick. I use Merrick cans, but am leery of their kibbled diets. I know a lot of people use it and love it so I s’pose that’s just one of my idiosyncrasies. : )

  • tilp

    I just got a dog. Dog food has changed a lot since my last one. Have not tried it, but merricks is a great dog food and they bought organix which is the only reason why I checked out their new line. I feed merricks to my cats also and the new organix cat line is way better than old so may give it a try too. Anyways, just bought the organix chic potatoes for dogs and it smells really good. My dog loved it. He ate beneful at his last house.

  • Betsy Greer

    Sounds yummy ~ my dogs will love it! I hadn’t read the review for this particular product. I’ll have to pick some up next time I’m in the pet food store. Have you tried Merrick Wing-A-Ling, also? Similar, I’m sure.

    We want to reassure you the chicken bones in ORGANIX® Butcher
    & Bushel Organic Choice Chicken Wing & Thigh Dinner with
    Fresh-Harvest Sweet Potatoes are there on purpose. If you notice on the
    can, there is a note from the chef that states the purpose of the
    chicken bones: “Our slow cooked, whole chicken thighs/wings are
    marinated tender chicken cooked on a softened bone.
    This special cooking process makes the bone soft and safe for your dog
    to enjoy. Feel free to serve whole, remove, or break apart the soft
    chicken bones for ease of pet consumption.”

  • Joanj

    Beware of this canned food! I found extremely large bones in 2 cans of this food. Definitely large enough to choke a dog. I will never buy it again.

  • Chrissy

    You found intestine in which brand? The brand I refer to in my post, or the Castor and Pollux? Just curious…I know that mine is not for this actual brand, but I could not find that brand on here – Thanks for the info!

  • Sbailey

     Just bought some and found intestine in it. Looks like they are not discriminating in the “parts” they throw in so I am returning it tomorrow.

  • Chrissy

    Has anyone ever heard of Hound and Gatos  (sp?) canned foods? Just curious. I saw them this weekend at a store and it looked pretty wonderful, especially for one of our dogs. We are still deciding which way to go for our little girl with the orthopedic needs and our 9 year old with the skin issues. We have considered raw, and then saw this can line…then our other little guy began vomiting bile (since Wed), so we have to take him to the vet tomorrow. He gets sick 1 time daily, he is eating, drinking, playing, taking treats, behaving just fine-other than the 1 episode a day. He is super skinny, yet is our most hyper active, so gets fed the most. He is currently on Fromm Four Star and has loved it. It is odd. We saw those cans and thought the ingredients were all meat- no fillers, or rice. Still thinking about foods for the pugs-always. Thank you for everything everyone has done for us! Appreciated always!

  • Addie

    were* giving him canned food only

    Just a side note, the dog couldn’t keep down any kibble at all. 

  • Addie

    A customer’s dog was having dietary issues after being on medication, so they was giving him canned food only to help his stomach better digest the food (after being on rice&chicken, and taking two different probiotics from the vet for a week) For some reason anytime he gets this food, he has to urinate a ton, once even doing so in the house which he hasn’t done in the three years they’ve owned him. Merricks, Evangers, and Weruva were all fine, no problems. Just wondering if there’s any ideas what makes this food different to cause that reaction? Needless to say they stopped feeding this food just to play it safe. 

  • Mike Sagman

    Hi Margie… Castor and Pollux Grain Free is already on my To Do list. However, due to my current backlog of products for review, it could be a while longer before I get to it. Thanks for the suggestion.

  • Margie

    There is a Castor and Pollux grain free Organix can food now, I just bought 4 cans at Petco in California, just thought I would let you all know.

  • goldenwds

    When we adopted our rescue Cocker Spaniel, he had been through a terrible time. He was recovering from malnourishment and from a family that a solider went off to Iraq. I was impressed with Organix’s list of ingredients and the absence of preservatives or fillers and believe the best food available to get him on the road to a healthy state. I believe mixing a cup Organix and cup home made dog food consisting of brown rice, ground Turkey, & Peas & Carrots. He shifts through his bowl picking out the ground Turkey, brown rice, Organix food while sparing eating the Peas & Carrots. He scatters his food around his bowel. I am absolutely impressed and slightly annoyed that I have to pick up the left over pieces from my floor. He is the apple of my mother-laws eye and loyally deserving dog and he is much happier with us and so are we with him.

  • nancy jo

    I have a six-year old boxer who has a very sensitive stomach.
    The vet recommended Hills Science Diet and he wouldn’t even touch it. I bought the Castor and Pollux Organic dry dog food and canned dog food and he just loves it. He hasn’t vomited at all since he has been eating this dog food and it’s been about 6 weeks since he started eating it.

  • Mike Sagman

    Hi Paige… I’d love to be able to help. But since I’m not a veterinarian, it would be misleading for me to suggest a particular food would be appropriate for a specific health condition. In any case, most vets recommend low fat foods to prevent pancreatitis (but not certain if that’s your vet’s diagnosis, here).

  • Paige

    I have been told by vets to feed my dog Hill Prescription Diet
    i/d canned food. According to the vets, my little Havanese, Dalilah has a weak pancreas. She does throw up very easily and cannot have any beef. She does not like the Hills food, and the ingredients are not quality foods. Do you have any suggestions?

  • Donna Prevett

    THE OUTFACING LABEL ON THE ‘ORGANIC TURKEY & ORGANIC VEGETABLES FORMULA’ dogfood should be re-printed to state ORGANIC TURKEY AND CHICKEN… since the fourth ingredient is Organic Chicken.

    I assumed that turkey was the only protein since the name of the flavor doesnt mention Chicken unless one looks at the ingredient lablel. THIS IS UNFORTUNATE SINCE MY DOG IS ALLERGIC to CHICKEN,-after she was fed this food, she fell ill.
