Dog Medical Diseases – Vitamin Deficiency
1. Vitamin A deficiency
(1) Causes Dogs require a large amount of vitamin A. If the green feed is not eaten for a long time, or the feed is boiled too much, the carotene will be destroyed, or the dog who suffers from chronic enteritis for a long time is susceptible to this disease.
(2) Symptoms The main symptoms are dry eye with night blindness, corneal thickening and turbidity, dry skin, disheveled coat, ataxia, and motor dysfunction. Anemia and physical failure may also occur.
(3) Treatment: Cod liver oil or vitamin A can be taken orally, 400 IU/kg body weight per day. Enough vitamin A should be ensured in the diets of pregnant dogs, lactating bitches and puppies. 0.5-1 ml of triple vitamins (containing vitamin A, vitamin Da and vitamin E) can be injected subcutaneously or intramuscularly, or in dog feed Add 1 drop of triple vitamins for 3 to 4 weeks.
2. Vitamin B deficiency
First, when thiamine hydrochloride (vitamin B1) is deficient, the dog may have irreparable neurological symptoms. The affected dog is wasting, anorexia, general weakness, impaired or lost vision, and sometimes has unstable gait and tremors, followed by paresis and convulsions.
Second, when riboflavin (vitamin Bz) is deficient, dogs suffer from cramps, anemia, bradycardia and collapse, as well as dry squamous dermatitis and hypertrophic steatodermatitis.
Third, when niacinamide and niacin (vitamin PP) are lacking. Black tongue disease is its characteristic, that is, the dog exhibits loss of appetite, thirst, flushing of the oral mucosa, dense pustules on the lips, buccal mucosa and the tip of the tongue, thickened tongue coating and gray-black (black tongue). There is a foul smell in the mouth, and sticky and foul-smelling saliva flows out, and some are accompanied by bloody diarrhea. The treatment of vitamin B deficiency should be based on the condition of the disease. When vitamin B1 is deficient, thiamine hydrochloride can be given orally to dogs at 10-25 mg/time. Or optimal thiamine orally taken 10-25 mg/time. When vitamin B2 is lacking, riboflavin 10 -20 mg/time can be taken orally. When vitamin PP is deficient, niacinamide or niacin can be taken orally at 0.2～0.6 mg/kg body weight.
