blood glucose levels in canines

Canine diabetes is a major health problem among the dogs. It is usually caused due to improper insulin production or insulin resistance. Insulin is a hormone that is produced by the beta cells of pancreas, to maintain blood glucose level and ensure cells are provided with glucose from the blood as a source of energy. The blood glucose levels may change due to the lack of or lower levels of insulin in the blood. This happens in canines too leading to ups and downs in blood glucose levels in canines. High glucose levels may lead to diabetes in canines.

Blood glucose levels in canines

For the canines too there are certain levels that are considered as normal. The normal levels for the dogs are between the range of 60mg/dL and 120mg/dL. If the blood sugar is more than 200 then the dog is diagnosed as a diabetic dog. It is also known as sugar diabetes. There are two other types of diabetes in dogs, mostly caused due to congenital defects, disease, trauma or prescribed drugs. They are nephrogenic diabetes insipidus and diabetes insipidus.


High glucose levels are more common in obese dogs. However, other reasons like viral infections, low immune system etc may cause canine diabetes. If the body produces very little or no insulin it causes the cells to be deprived of a major energy source. This is type 1 diabetes. Sometimes the body’s cells show resistance to insulin causing the sugar to remain in the blood stream. This is Type II diabetes. The result is an increase in the blood sugar levels or hyperglycemia, a characteristic of diabetes mellitus. Without insulin the body may starve causing organ damage like blindness or nerve and muscle weakness. German shepherds, keeshonds, golden retrievers, poodles, schnauzers, dachshunds, cocker spaniels are at a higher risk of developing diabetes mellitus it more likely to be found in female dogs and older dogs. Canine diabetes is most common between ages seven and nine.
