Signs Your Dog Might Be Diabetic (Video)

1. Increased Thirst

Increased thirst is one of the earliest signs of diabetes. Your dog’s desire for more and more water will steadily increase over time. When glucose levels increase in the bloodstream, the kidneys cannot distribute water throughout the body, which can lead to dehydration or sub-normal fluid levels in your dog.

2. Excess Urination

Because of the increase in water intake, you may notice changes in your dog’s bathroom habits. The increase of glucose in the bloodstream can also create more urine production. So, your dog could start asking to be taken out more frequently and/or could urinate longer when he does go. In addition, this could also lead your well house-trained dog to have more indoor accidents and possibly contract bladder infections.

3. Lack of Energy

Being less energetic can also be a sign of diabetes in your dog. They may seem tired for no reason, sleep more, and not be as interested in physical activities. Insulin production declines with diabetes, meaning that your dog’s body lacks the fuel it needs to be energetic. With this sign, be sure to observe your dog first to make sure they’re not just tired from normal day-to-day activities before concluding that something is actually wrong.

4. Cloudy Eyes

Cataracts are common in dogs who have diabetes. Cataracts happen when the lens of the eyes thicken. You may notice your dog’s eyes begin to look whiter. This can lead to them running into walls or furniture around the house. Even if your dog is currently being treated for diabetes, he can still get cataracts. If cataracts form, your dog could eventually become permanently blind.

5. Weight loss

Your dog may seem to have a huge appetite but still lose weight. This is due to the fact that your dog’s body can’t use the energy they’re getting from the food they’re eating. Without insulin, glucose can’t get into the cells. Therefore, this results in no weight gain from food. Watch your dog’s habits and make sure he isn’t just super hungry. If your dog is diabetic and losing weight, consider calling your vet for help.
