Dog Calcium Intake Calculator
Here’s a basic table outlining the recommended calcium intake for dogs, depending on their age, size, and life stage, along with sources and potential risks of calcium deficiency or excess. These guidelines are based on veterinary recommendations, but always consult your vet for specific advice related to your dog's needs.
| Category | Daily Calcium Intake | Sources of Calcium | Symptoms of Deficiency | Symptoms of Excess (Hypercalcemia) |
|---|---|---|---|---|
| Puppies (growing) | 320 mg Ca per kg of diet | Puppy food, bone meal, calcium powder | Poor growth, bone deformities, dental issues | Excessive thirst, urination, lethargy, kidney damage |
| Adult Dogs (small breed) | 100–200 mg Ca per kg of body weight | Balanced dog food, yogurt, cheese | Weak bones, muscle tremors, lethargy | Vomiting, decreased appetite, calcium deposits in organs |
| Adult Dogs (large breed) | 100–200 mg Ca per kg of body weight | Commercial large-breed food, fish, broccoli | Joint problems, brittle bones, muscle cramps | Dehydration, bone pain, kidney stones |
| Pregnant/Lactating | 800–1200 mg Ca per kg of diet | High-quality dog food, supplements | Weak pups, poor milk production, skeletal issues | Nausea, muscle weakness, seizures |
| Senior Dogs | 100 mg Ca per kg of body weight | Fortified dog food, fish, leafy greens | Osteoporosis, arthritis, dental problems | Heart issues, impaired kidney function, abnormal bone growth |
Notes:
- Puppies and Pregnant/Lactating dogs need higher calcium due to the demands of bone growth and milk production.
- Large breed puppies should avoid excess calcium to prevent rapid growth, which can lead to joint issues.
- Always balance calcium with phosphorus (generally 1:1 or 2:1 ratio) to ensure proper absorption and bone health.
Calcium supplements should only be added under the guidance of a veterinarian to avoid imbalances or toxicity.
