The causes of hypoglycemia in dogs:

1. Excessive secretion of insulin (such as islet cell tumor), liver glucose storage and conversion disorders (such as fatty liver, hepatic Sclerosis), adrenal insufficiency, pituitary insufficiency, central nervous system disorders, cachexia and other factors can cause hypoglycemia.

2. Puppies under 3 months old often suffer from hypoglycemia, which is caused by cold, hunger or gastrointestinal disorders.

3. Hypoglycemia in female dogs is mostly caused by excessive litter size, increased nutritional needs and large amounts of lactation after delivery.

Clinical symptoms of hypoglycemia in dogs:

1. The sick dog has general weakness, paroxysmal neurological symptoms, muscle spasms, motor ataxia, and often Causes blindness.

2. Puppies are depressed at the beginning of the disease, with unsteady gait, facial muscle twitching, and body spasms. They soon fall into a coma, and their blood sugar can drop to 30 mg per 100 milliliters.

3. The female dog has muscle spasms, general tonic or intermittent spasms, body temperature rises to 41 to 42 degrees, breathing and heartbeat accelerate, and urine ketone body test is positive.

4. The blood sugar level is reduced (less than 50 mg%) and the insulin concentration in the plasma is increased. However, due to hypoglycemia caused by causes other than islet cell tumor, the insulin cord concentration is normal or low. In addition, the glucose tolerance test has high diagnostic significance for this disease.
