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

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

The fourth ingredient is organic pea flour, a powder made from roasted yellow peas. Pea flour contains as much as 25% protein, a factor that must be considered when judging the meat content of this dog food.

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

The sixth ingredient is organic 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 organic flaxseed, one of the best plant sources of healthy omega-3 fatty acids. Provided they’ve first been ground into a meal, 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.

The eighth ingredient includes organic apples, a nutrient-rich fruit that’s also high in fiber.

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.

Grain Free 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 Grain Free 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 27% and estimated carbohydrates of about 31%.

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 canned dog food.

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

However, with 51% of the total calories in our example coming from fat versus just 26% from protein, some recipes may not be suitable for every animal.

Bottom line?

Castor and Pollux Organix Grain Free 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.

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.

    Some companies don’t use cans with bpa. You have to ask the company exactly what kind of cans they use.

  • Katharine MacAlister

    Pressure cooked inside the can? Is the can BPA free and I assume there are heavy metals in it. Why is is cooked inside the can? Does not sound good to me?

  • charles sim

    um not everyone is looking for high protein for example my dog has liver issues high protein is bad for that also not all my dogs are active so to have high carb is also bad. I get enough protein and carbs from kibble Im just looking to mix this for moisture to help with dehydration. so lower protien and carb then others is a huge plus for me. I mix with arcana dog food.

  • Michael Bernath

    I was shocked to find a big thigh bone in a can today. But after reading the comments and watching the YouTube video, I tried to crush the bone with my fingers to see if it really was soft, and in fact it was so soft it turned to mush and was clearly harmless. I fed it to my dogs and they loved it. Over all, the quality of C&P chicken thigh dog food is the same or better than the quality of chicken stew I make for myself. I will keep buying it for my dogs, but I will also always check the softness of any bones I find, before feeding them to my dogs. Nutritionally I’m sure they are wonderful, but with comments here about sharp, hard shards, I think it’s important and prudent to test the safety of any bone pieces before giving them to pets.

  • It’s still highly recommended because there are still hundreds more foods that are below it (less than 4 stars). Foods with 3 stars and higher are recommended.

    In the Bottom Line sub, it is stated that “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%.”
    But then you state that the food contains a “Below-average protein. Below-average fat. And above-average carbs when compared to a typical canned dog food.” yet you also say that it is highly recommended? Please explain

  • Claire Leone Skody

    I too bought several cans of this dog food. Fortunately for my dog, we mix it with her dry food & were able to find the large thigh bone & shards of bone mixed in with the food. I am SURE that if ingested, my dog would have gotten seriously ill or died. The bones were neither soft (actually very sharp) or digestible. When I called the company they gave me the same crap about how the bones were “supposed” to be in the food. When I asked if shards of bone were also supposed to be in the food, she couldn’t answer me. I also called the pet store where I purchased the food, they were going to pull the batch.
    Bottom line, I will never purchase this food again & I don’t recommend it to anyone else!!

  • My dogs love the merrick smothered comfort food with the chicken thigh in it. They have some Wingaling to try too but I’m sure they’ll love it as well. Every now and then they just a raw meaty bone to eat. They get chicken, pork, duck and sardines (raw, bone and all).

  • Charlie

    Patty is a fraud her information is flawed.

  • Pattyvaughn

    I never understand why people who don’t care what anyone says think that someone will care what they say.

  • Cavalier mom

    Didn’t you Hounddog feed Purina until 2-3years ago?and how old?23? Don’t you think that you are a bit too young to be that arrogant???:):):)

  • Hound Dog Mom

    The bones are supposed to be there. From Castor & Pollux’s website:

    “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.” The bones also provide the full flavor your dog loves. The food is pressure cooked inside the can and this process is what softens the bones.'”

    I know you said you don’t care what anyone says, but I’ll say it anyways – poultry bones are very safe as long as they are raw or have been pressure cooked for a long period of time to soften (such is the case with this food).

  • Trillian6

    I also just found a Huge chicken bone in the wing & thigh dinner I bought. I’m sorry but I don’t care what anyone says here, chicken bones are DANGEROUS!! I’m not going to buy anyone stating that they’re Good for my dog to eat. I didn’t rescue him to put him in Any danger. That would be reckless endangerment IMHO.

  • Jan_Mom2Cavs

    I don’t know why you responded to me, I didn’t say anything about the bones…I know all about them. I’ve used Merrick cans for years.

  • Tom Lewandowski

    Do any of you with “bone” comments read the can? The bones are supposed to be in there and are safe to eat. The chicken is so slowly cooked … ON THE BONES .. resulting in bones that a child can easily crush by hand. The dogs love them, they contain some nutrition, and I give them to my dogs as treats!

  • Kelpi

    I recently purchased some of the C&P Organix Butcher and Bushel Chicken Wing and Thigh Dinner, and yes, there are bones in it but they are very soft and almost disintergrate when pushed with a fork. The bones don’t bother me as they are not sharp, at least I haven’t seen any sharp ones. And bones are an excellent source of many things to include, I believe, calcium. I just mix it all up. Some of the wet food, some of the C&P dry kibble and whatever else I may add that day, ie: egg, pumpkin or organic rice, etc..
    I LOVE C&P pet food, am extremely satisfied and feel that I am feeding my dogs a superb, high quality food. My dogs are very healthy. I also buy their line because it is ORGANIC, and that is the number one priority for me.
    And last but not least, my dogs like the food.
    Obviously, I highly recommend this dog food.

  • Diane

    I use the Organix Butcher & Bushel (chicken wing & thigh with sweet potatoes). Since I only put a couple of teaspoons on top of their dry food, and then mix in all together, when I find bones I just remove them. So far I have had good luck with this canned food.

  • Annie

    I gave my dogs some Organix Butcher and Bushel Chicken Wing and Thigh Dinner w/Sweet Potatoes as a topper. The next morning, one had an explosive accident in the house for the first time ever, then the following morning, the other had bloody diarrhea. Both are fine eating raw chicken, so don’t think the amount of bone mentioned by others was a problem, especially because they only got a quarter can each. Contacted Castor & Pollux via 800 number on the can. They said they hadn’t gotten other reports, but took the batch number off the can and will check the reserved quality control for that batch. They are issuing a refund, too. Don’t know what the big picture might be, but just a heads up that there seemed to be something wrong with the can I purchased.

  • m young

    YES! I just returned two cans to Whole Foods advising them there were whole chicken wing bones inside! Bad, bad, bad. My dog almost ate them. Gross too!

  • jjack

    I found bones in the canned food as well. What the heck??? Some of them where sharp.

  • Maxx n Zoeys mom

    Huge bones in the food I just bought!

  • Jan_Mom2Cavs

    Just got some of this canned food at Whole Foods, along with the Ultramix grainfree cans….they were 1.50 each, so not bad.  Hopefully my dogs will like their kibble topped with it and do well with it.
