The vitamins are an important part of the dog’s nutritional needs, and different vitamins have different effects. Therefore, the lack of any kind of vitamins may have a serious impact on their bodies. Of course, there are also primary and secondary nutritional needs. Let’s first understand what the three essential vitamins are for dogs.
1. Vitamin A: Vitamin A is a fat soluble vitamin, which mainly exists in animal feed. Plant feed does not contain vitamin A, but β – carotene contained in it can be converted into vitamin A in dogs. The main physiological function of vitamin A is to maintain normal vision and normal physiological function of mucosal epithelial cells. When the dog is lack of vitamin A, it firstly shows that the dog’s dark adaptability is reduced and even suffers from night blindness and dry eye disease. The dog’s cornea is thickened and keratinized, forming cloud like, sometimes ulcers and perforations, even blindness; growth is blocked and weight loss occurs. In the absence of vitamin A, the fecundity of male dogs will decrease; in the female dogs, difficult pregnancy, abortion, stillbirth, weak birth and blind puppies will occur; in the young dogs, disease resistance will weaken, diarrhea will occur, and optic atrophy will lead to blindness, often resulting in pneumonia and death.
2. Vitamin C: Vitamin C is also called ascorbic acid. In dogs, vitamin C can be partially synthesized. Under normal circumstances, vitamin C deficiency is not easy to occur. However, the growth speed of puppies is fast, and vitamin C deficiency is easy to occur. In addition, the decline of synthetic vitamin function can also lead to vitamin C deficiency. The main manifestations of vitamin C deficiency are gingival bleeding, blood vessel embrittlement, the decline of the body’s resistance to disease, and the influence of iron absorption. Some fruits and vegetables are rich in vitamin C, but these foods are not palatable to dogs. The way to supplement vitamin C is to add vitamin C tablets to dog food. But some parents say that dogs don’t like vegetables! But what’s the benefit of eating vegetables for dogs? Dogs don’t like vegetables or some kinds of vegetables, because dogs don’t like the special taste of some vegetables or because the vegetables contain more crude fiber, are not easy to chew, are difficult to swallow, and the habit of dogs picking food.
3. The main physiological function of vitamin D is to regulate the metabolism of calcium and phosphorus in the body, maintain the normal concentration of calcium and phosphorus in the blood, so as to promote the calcification and normal development of teeth and bones. The lack of vitamin D in dogs can not maintain the balance of calcium and phosphorus, which leads to bone diseases. Rickets may occur in young dogs, weight loss, emaciation, anemia, necrosis of tail tip, convulsion, etc.; osteoporosis may occur in adult dogs.
