Symptoms and dangers of excessive calcium supplementation in dogs Short-term oral intake of excessive calcium Most of the excess calcium will be excreted through the feces, mainly increasing the burden on the dog’s stomach and intestines, except for individual dogs may occur anorexia, constipation, indigestion and other mild symptoms, generally will not occur more serious reactions. Long-term excessive calcium supplementation 1. causes long-term hypercalciuria, increasing the chances of urinary system formation of stones; 2. leads to premature calcification of cartilage, premature closure of fontanelle, the formation of small head deformity, restricting the dog’s brain development; 3. premature calcification of bones, early closure of epiphysis, the development of long bones is affected, the final height is limited; 4. too much calcium in the bone, the bone becomes brittle, prone to fractures; 5. Affect the appetite of dogs, thus affecting the absorption of other nutrients in the intestine; 6. Excessive calcium in the intestine will inhibit the absorption of divalent ions such as iron and zinc, causing secondary zinc and iron deficiency, and leading to a decrease in immunity, anorexia, slow growth, anemia, fatigue and other corresponding symptoms in dogs; excessive blood calcium concentration, so that calcium deposited in internal organs or tissues, if deposited around the cornea will affect vision, in the heart If the calcium is deposited in the corneal periphery, it will affect the vision, in the heart valve, it will affect the heart function, and in the blood vessel wall, it will aggravate the vascular sclerosis. This is a prerequisite for the diagnosis of calcium overdose. The next step is to combine skeletal x-rays for early bone age, abnormal tissue calcification and excessive urine calcium. Correcting calcium overdose in dogs Once an overdose is detected, the calcium supplementation should be stopped or the dose of calcium should be adjusted promptly. The symptoms of calcium overdose will usually disappear as soon as the dose of calcium and vitamin D are properly adjusted. However, once calcification of the bones has formed, there is often no good way to eliminate it. Avoiding another overdose of calcium and vitamin D preparations is probably the best measure to delay further calcification. The most important thing to consider when giving calcium to your dog is 1. Calcium absorption is not exactly as people want it to be: how much is supplemented and how much is absorbed; the more it is supplemented, the more it is absorbed. How much calcium is absorbed in the gastrointestinal mainly depends on the calcium nutrition status of the dog at the time, regulated by the baby’s body activation of vitamin D hormone, parathyroid hormone and other substances. Vitamin D promotes the absorption of calcium in the intestine. When vitamin D is deficient, even if more calcium is supplemented, it is not well absorbed. Vitamin D also inhibits the excretion of calcium by the kidneys and promotes the decalcification of old bone.2. Food calcium supplementation is generally safest than medication, and eating normal food will not cause calcium overdose. In addition to dairy products, soy products, shrimp, fish and other foods can be given to supplement. Sun exposure and outdoor exercise are beneficial to calcium absorption and utilization and are one of the safe ways to supplement calcium.
