This calculator assumes you’re inputting the weight of the dog’s food in kilograms or pounds and provides the corresponding Vitamin D range in IU that should be added to the food based on the provided minimum and maximum requirements. Always consult with a veterinarian for the most accurate and safe dietary recommendations for your pet.

If you feed a raw food diet with a good variety of proteins and organ meats, I would select a vitamin D dose in between 25% and 50%.

What are some natural sources for vitamin D you can give to dogs?

Natural sources of vitamin D for dogs include various foods such as salmon, liver, eggs, yogurt, kefir, cheese, fish, and beef [1][3][4]. These sources provide essential vitamin D that supports bone health, calcium balance, muscle function, and overall well-being in dogs. It’s important to note that vitamin D is a fat-soluble vitamin, meaning excess amounts are stored in the body and can lead to toxicity if given in large doses[2].

While dogs can obtain vitamin D from their diet, it’s crucial to ensure they receive adequate levels without exceeding safe limits. Commercial pet foods typically contain the necessary amount of vitamin D required by dogs; however, if you are feeding a home-prepared diet, consulting an animal naturopath with expertise in veterinary nutrition is recommended to ensure your dog’s nutritional needs are met[2].

In cases where supplementation is necessary due to concerns about insufficient vitamin D intake, it’s advisable to choose vet-quality multivitamin supplements formulated specifically for dogs. These supplements can help provide balanced levels of essential nutrients like vitamin D to support your dog’s health and well-being[3].

Need help with your pet?

Do you have health issues that you cannot resolve with conventional therapies? Are you looking for a natural approach to help your pet live a long healthy life?

This is possible, and what I do. My approach is to restore the immune system in dogs and cats so they can achieve homeostasis. That is the best protection against pathogens that can lead to diseases.
