Vitamin D Deficiency (Rickets)

infoResearch indicates: Rickets remains common in pets fed all-meat or homemade diets without proper supplementation

descriptionOverview

Unlike humans, dogs and cats cannot synthesize vitamin D from sunlight — studies confirm that puppies develop rickets even with UV exposure if their diet lacks vitamin D. This means every microgram must come from food. Vitamin D controls calcium and phosphorus absorption; without it, bones become soft and bendable. Rickets is most common in growing pets fed unbalanced homemade diets or all-meat diets without organ meats.

restaurantHow Nutrition Helps

Prevention is simple: feed a complete, balanced commercial diet that meets AAFCO standards. For those feeding homemade diets, vitamin D supplementation under veterinary guidance is essential. The richest natural sources are fatty fish, liver, and egg yolks. But be careful — vitamin D toxicity is dangerous and can cause kidney failure, so never supplement without veterinary supervision.

Gentle activity promotes bone development, but puppies with rickets should avoid high-impact exercise until bones strengthen with dietary correction.
