Dogs’ eyes become cloudy

People with diabetes may also develop cataracts, and dogs are no exception. Sick dogs may also be at risk of developing cataracts.

Dogs are in low spirits

A late sign of diabetes is ketoacidosis, a metabolic acidosis caused by the breakdown of fat and protein in the liver, which reduces the body's response to insulin. The presence of large amounts of ketone bodies in the body is toxic, and this imbalance can lead to depression in dogs.

Vomiting in dogs

If the dog has been diagnosed with ketoacidosis when it has diabetes, another common side effect of ketoacidosis is vomiting. Ketoacidosis is more common in older and female animals. Dachshunds and miniature poodles are also affected.
