Cracking the Case: Calcium Content in Greenies Treats


Greenies are a popular brand of dental chews for both dogs and cats. They come in various flavors and sizes, enticing pet owners with the promise of cleaner teeth and fresher breath for their furry companions. But one question often lingers:  Do Greenies contain calcium, and if so, how much?  This seemingly simple question delves into the world of pet nutrition and the importance of a balanced diet.

Calcium: A Cornerstone of Pet Health

Calcium is a crucial mineral for both dogs and cats. It plays a vital role in building and maintaining strong bones and teeth, regulating muscle function, and supporting nerve transmission. Deficiencies can lead to a variety of health problems, including:

  • Skeletal abnormalities: In growing puppies and kittens, calcium deficiency can cause rickets, a condition characterized by weak and deformed bones.
  • Osteoporosis: In adult and senior pets, low calcium levels can contribute to osteoporosis, a condition that makes bones brittle and prone to fractures.
  • Muscle weakness and cramps: Calcium is essential for proper muscle function. Without sufficient calcium, pets may experience muscle weakness, tremors, and cramps.

However, excessive calcium intake can also be detrimental. It can interfere with the absorption of other minerals like phosphorus and iron, leading to digestive issues and even kidney stones in some cases.

Unveiling the Calcium Content of Greenies

The good news is that Greenies do contain calcium. The exact amount varies depending on the specific treatment type and size. Here’s a breakdown to help you understand better:

Table: Calcium Content in Greenies 

Treat Type Flavor Calcium Content (as-fed basis) Calcium Content (dry matter basis)
Greenies Feline Oven Roasted Chicken 1.206% 1.34%

Please note: This table represents the calcium content for one specific Greenies Feline variety.  It’s important to check the individual packaging for the exact calcium content of the Greenies treat you plan to give your pet.

Understanding What the Numbers Mean

The table provides two values for calcium content: as-fed basis and dry matter basis. Here’s what they signify:

  • As-fed basis: This represents the amount of calcium per 100 grams of the treat in its original state, including moisture content.
  • Dry matter basis: This represents the amount of calcium per 100 grams of the treat after removing the moisture content.

The dry matter basis offers a more accurate comparison of calcium content across different treats as it eliminates the influence of moisture variation.

How Does Greenies’ Calcium Content Compare?

Unfortunately, there’s no single answer to this question. The calcium content in Greenies can be lower or higher compared to other dental chews depending on the specific brand and formula.  Here’s how you can compare:

  1. Check the Ingredient List: Look for ingredients like calcium carbonate, dicalcium phosphate, or bone meal. These are common sources of added calcium in pet treats.
  2. Compare the Calcium Content: Once you’ve identified treats with added calcium, compare the percentage values on the packaging, focusing on the dry matter basis for better accuracy.

Making Informed Choices: Greenies and Your Pet’s Calcium Needs

Now that you understand Greenies’ calcium content, how can you incorporate this knowledge into your pet’s overall diet? Here are some key points to consider:

  1. Consult Your Veterinarian: Every pet has unique dietary needs. Discuss your pet’s age, breed, overall health, and current diet with your veterinarian. They can advise you on the appropriate amount of calcium your pet requires and whether Greenies are a suitable fit.
  2. Consider Your Pet’s Complete Diet: Greenies are treats, not replacements for a balanced diet. Your pet’s primary source of calcium should come from their regular food. Look for high-quality dog or cat food formulated to meet their specific needs.
  3. Monitor Treat Intake: While Greenies can be a helpful tool for dental hygiene, avoid overindulgence. Excessive treat consumption can lead to an imbalance of nutrients, including calcium. Follow the recommended serving size based on your pet’s weight and adjust accordingly if needed.


Greenies do contain calcium, which can be beneficial for your pet’s health. However, the quantity varies depending on the specific treatment type. Remember, Greenies are treats, and your pet’s primary source of calcium should come from their regular diet.  Always consult your veterinarian for personalized advice on your pet’s calcium requirements and the role Greenies can play in their overall dental health plan.
