Symptoms of calcium deficiency in dogs:

1. Bone deformation: If young dogs are deficient in calcium, they are prone to rib valgus, forelimb wrist joints, and elbows. Joint deformation, adult dogs are prone to "O" shaped legs and deformed forelimbs. For some dogs that are susceptible to intervertebral disc disease, such as pugs, poodles, etc., if they are 2 to 3 months old, an important period for intervertebral disc formation, calcium deficiency will occur in adulthood and become a lifelong pain.

2. Slow tooth growth: Dogs begin to grow permanent teeth when they are 4 to 6 months old, and at the same time, the deciduous teeth in the mouth begin to fall out. At this time, calcium deficiency will cause slow growth of wisdom teeth, failure of deciduous teeth to fall out, thin tooth enamel layer, and weak tooth structure, making it easy for double rows of teeth or uneven permanent teeth to grow. These dogs are prone to diseases such as bad breath and gingivitis in adulthood.

3. Twitching of limbs: Dogs after giving birth are prone to acute postpartum calcium deficiency due to low blood calcium concentration. Dogs have twitching limbs, stiff body, difficulty breathing, and inability to stand, and their body temperature can rise to 40 degrees Celsius. Above ℃, it may even cause coma and death.

4. Easy to fracture: Calcium deficiency in dogs can cause osteoporosis. At this time, the bones become fragile, which will increase the incidence of bone spurs and fractures in dogs.

Causes of calcium deficiency in dogs:

1. Unbalanced nutritional ratio of diet: If a dog is fed a single food for a long time, the nutritional ratio of the food will not be balanced. Balanced, insufficient calcium content will lead to calcium deficiency in dogs.

2. The dog’s own absorption capacity is weak: If the dog has absorbed enough calcium in its daily diet, but due to its weak absorption capacity, it cannot absorb enough calcium, which will also cause the dog to be calcium deficient. .

3. Poor calcium conversion in the body: Although some dogs have absorbed calcium from food, due to poor calcium conversion in the body, calcium will be excreted from the body, leading to calcium deficiency.

4. Long-term consumption of animal liver foods: Animal livers contain high concentrations of vitamin A. If dogs are fed animal liver foods for a long time, it will easily lead to excessive vitamin A intake. Too much vitamin A inhibits the dog's absorption of vitamin D. When the dog's body is deficient in vitamin D, it can also lead to calcium deficiency.
