About Castor & Pollux Dog Food

Castor & Pollux Natural Pet Works describes itself as a leader in organic and natural pet products. They make Organix and Pristine dog foods and Good Buddy pet treats.

Organix was founded in 1999 in Clackamas, Oregon. Organix, certified organic food and treats for dogs and cats, debuted in March 2003. In 2011, the first organic, grain free food for dogs was launched by Castor & Pollux.

In April 2012 the company was purchased by Merrick Pet Care, based in Amarillo, Texas. Merrick has canning and dry pet food operations in Texas and they have organic certification under the USDA National Organic Program (NOP) for all of their Texas manufacturing facilities. Merrick Pet Care, Inc., is the only organic certified manufacturer for both dry and canned food for pets.

Merrick, along with Castor & Pollux, were purchased by Nestle Purina PetCare in 2015. They appear to remain semi-autonomous from Purina at this time.

Since that time, Castor & Pollux raised all of their Organix recipes to be USDA organic certified. The company also introduced the product line called Pristine, a complete line of foods made with responsibly-sourced ingredients.

Sourcing And Manufacturing

Many people are often under the impression that any product with organic ingredients can be called “organic.” There are a lot of regulations concerning the use of the term “organic” in the U.S., along with strict labeling standards. It is impressive that Castor & Pollux has an entire line of dog food with numerous recipes that are USDA organic certified.

Since the Organix foods are USDA Organic Certified, that means several things with regards to the ingredients. The organic ingredients are produced without chemical pesticides, synthetic fertilizers, artificial preservatives, or added growth hormones or antibodies. The recipes contain no corn, wheat, or soy. The organic ingredients are always non-GMO. Ten of the recipes are non-GMO Project Verified. And, they are cooked in the U.S. in an organically certified kitchen.

The Organix recipes always use organic free-range chicken or turkey.

According to customer service, all of their ingredients are sourced from the United States depending on availability. If for some reason they are unable to get them within the United States they will then source vitamins from Germany or Canada, their rabbit from France and their venison from New Zealand.

Castor & Pollux are made at the Merrick facilities in Texas. Merrick is organic certified to make both dry and wet/canned foods for pets.

Recall History

The most recent recall we found for Castor & Pollux is from May 2018. It refers to two of their Good Buddy products, along with several Merrick Backcountry products. The recall was announced due to elevated levels of beef thyroid hormone.

There were previous FDA recalls of Castor & Pollux Natural Ultramix and Good Buddy pressed rawhides but they were years ago.

Merrick Pet Care, Inc. has had a number of FDA recalls in the past, but they were prior to 2012 when the company purchased Castor & Pollux.

What Kinds Of Dog Food Does Castor & Pollux Offer?

You can see all of the recipes made by Castor & Pollux on their web pages.

Not all organic products are the same, depending on the percentage of organic ingredients a product contains. For example, a food could be 70-94 percent organic (“made with”); or 95-99 percent organic (“organic”); or 100 percent organic (“100 percent certified organic”). These foods would receive different organic labeling.

All of the Castor & Pollux Organix line foods today are USDA Organic Certified – made with 95 to 99 percent certified organic ingredients. That includes their kibble and wet/canned foods.

Their Organix formulas include dry, wet/canned, freeze-dried raw, meal toppers, and treats. Most recipes are grain-free but they have some which are grain-inclusive.

The Pristine formulas use some organic ingredients but not all of their ingredients are organic. The first ingredient is always meat or poultry that is responsibly raised without any antibiotics or hormones, or fish that is wild caught. Fruits and vegetables are grown without any synthetic fertilizers or chemical pesticides. The recipes do not contain grain, corn, soy, wheat or gluten ingredients. The recipes do not use any artificial preservatives, flavors or colors. Formulas include dry, wet/canned, freeze-dried raw, meal toppers, and treats. All formulas are grain-free.

How Much Does Castor & Pollux Dog Food Cost?

Castor & Pollux diets cost much more than other premium dog foods.

What Do Customers Think Of Castor & Pollux Dog Food?

Castor & Pollux gets good ratings from most customers. Most customers (over 90 percent) say they would recommend various Castor & Pollux dog foods to others. Many recipes (over 70 percent) get 4- or 5-star reviews.

Overall, Is Castor & Pollux Dog Food A Good Choice?

We don’t think that this brand is as good as it once was. Many people will be happy with the organic label and overlook the fact that virtually all recipes have been stuffed with legumes, including grain-inclusive recipes. Even organic legumes (peas, chickpeas, and lentils) are still legumes.

Some of these ingredients are very high in the ingredient list. If you are concerned about these ingredients in your dog’s food, you should not buy dog foods that contain them just because they are organic.

If these ingredients don’t bother you or your dog, you will be happy with this brand.

Where Is Castor & Pollux Dog Food Sold?

You can find Castor & Pollux dog food at Chewy.com and other online retailers. You can also buy Castor & Pollux at some pet supply stores.
