(1) Chinese cabbage. Chinese cabbage is rich in vitamins, and eating more cold lettuce can protect the kidneys.

(2) fish. Fish contains omega-3 fatty acids, which are anti-inflammatory substances and can prevent nephritis.

(3) broccoli. Broccoli is not only nutritious, but also has the function of eliminating toxins from the body. It can decompress and protect the kidneys.

On the premise of ensuring a balanced diet for dogs as much as possible, pet owners should also supplement vitamins appropriately. Dogs with renal failure often have no appetite. Vitamin B is very important for the health and appetite of the digestive system in dogs. You can feed vitamin B to keep enough B vitamins in your dog's blood. If necessary, it is suggested to use feeding method to make the food into a fine paste and feed it slowly with a syringe or feeder several times a day to prevent the dog from choking.

What should dogs with renal failure pay attention to?

1 Avoid a high-protein diet. The final product of protein's metabolism is urea, which is hydrolyzed by the liver and finally excreted in the form of urine through renal filtration. Therefore, a high-protein diet will increase the burden on the kidneys, and at the same time, urea that cannot be metabolized will enter the blood, causing an increase in blood urea nitrogen, leading to the occurrence of azotemia.

At the same time, some non-essential amino acids contained in high-protein diets will produce a large amount of acid-containing waste during metabolism. These wastes can not be excluded from the body when renal failure occurs, and will accumulate in the body, causing acidosis in dogs and cats. Usually, when eating, we should pay attention to keeping the dog's nutrition balanced, and also eat some good food to relieve the dog's abnormal urine.

If the dog is diagnosed with nephritis, be sure to give the dog less salt. Serious will lead to the death of cats and dogs. Therefore, controlling protein intake of dogs and cats and reducing blood urea nitrogen is one of the important means to treat renal failure.

2 Avoid high-phosphorus diet, the filtering function of kidney will decrease when renal failure occurs, and the organic phosphorus and inorganic phosphorus in food cannot be excluded from the body. The accumulation of these phosphorus elements in the body causes the increase of blood phosphorus, which leads to the imbalance of calcium and phosphorus ratio, and finally leads to the dysfunction of parathyroid, followed by skin itching, arteriosclerosis, bone cellulose, renal osteopathy, and even the death of dogs and cats in severe cases. Therefore, controlling phosphorus intake and preventing hyperphosphatemia are also the key to treat renal failure.
