- Diabetes is a result of insufficient amounts of insulin in the body. In dogs, it typically occurs after 5 years of age, but when it occurs in young dogs, it's often because of a birth defect in which the pancreas is malformed. It can also be due to puppy diseases such as parvovirus.
- Lack of insulin means that glucose cannot get into the body's cells to provide energy. Diabetic puppies will often exhibit tiredness and a desire to sleep.
- Puppies with diabetes will crave water.
- High blood sugar levels cause a decrease in water retention and therefore an increase in water elimination. That means more peeing.
- Puppies with diabetes often lose weight despite being continuously hungry. The body burns muscle to compensate for the lack of glucose for energy.
