Castor & Pollux Natural Ultramix Grain-Free Dog Food Review

Castor & Pollux Natural Ultramix Grain-Free Dog Food Review

Our Recommendation

Wow! This food has a lot of different proteins in it! I immediately noticed that this is a food that has a complex of different flavors that your pooch will love. Duck, turkey, lamb, salmon, and a variety of fruits and vegetables make this food well balanced and nutritionally complete.

  • No artificial colors or flavors.
  • Free of animal by-products.
  • Real meat makes up the first four ingredients.
  • Antioxidant-rich fruits like blueberries provide immune system support.
  • Added probiotics help with digestion and nutrient absorption.
  • Completely grain-free.
  • Suitable for sensitive dogs and those with allergies.
  • Salmon oil adds valuable Omega-3 and 6 fatty acids for a gorgeous coat and great skin.

Castor & Pollux are one of the major producers of natural and organic dog foods. I recommend this formula for any dog parent that wants a quality dog food that offers a complex flavor profile and superior balance of ingredients. There is no question that this is a superior dog food that your dog will eat with relish! We also got our hands on Castor & Pollux Organix Grain-Free Organic Dog Food and would also recommend it for your dogs.

Each year the AAFCO publishes two sets of nutritional minimum standards for dog food intended to help specify if a food is suitable for:

1. Dogs in the growth & reproduction phases of life

Transition Instructions

Gradually replace your dog’s normal dog food with Castor & Pollux over the course of 5-10 days depending on how sensitive your dog is. Most dogs are totally fine with a five-day transition time, but if your dog has been prone to stomach issues in the past you may want to increase the transition period to 7-10 days.

Since Castor & Pollux is a grain-free formula with concentrated nutrition and calories, you may find that you may need to feed your dog a lower volume of dog food. Check the feeding chart below and compare it to the volume of food you were giving your dog when feeding the old brand. This will prevent overfeeding and help you get the most out of a bag.

Feeding Amounts

Depending on your dog’s size and activity level, they may need more or less food in their daily feeding amounts.

The Bottom Line

This dog food is great for just about any dog. The combination of quality meats, fruits, and veggies, with added probiotics, vitamins, and minerals, makes a balanced ration that you can feel good about giving your pet. This food would also be a great choice for pet parents that have picky eaters or pooches with sensitive stomachs or allergies. Castor & Pollux have a lot of formulations so there is something for every dog that is a member of your family.
