The Top Ten Signs of Diabetes in Dogs

Much like we have seen a rapid increase in diabetes in humans over the past few decades, an uptick of the condition in our pets has also occurred. Many people believe that the processed diet that is often provided to humans and animals alike is responsible, while others have suggested that over-consumption of food is to blame. Whatever the case, it is never good to find out your pet is suffering from the disease.

If you believe your beloved dog has diabetes, then you want to get to the bottom of it as soon as possible. Below, we’ll outline the top ten signs you need to look out for if you suspect your dog is currently suffering from diabetes.

Excessive Thirst

Diabetes is known to dehydrate pets and humans alike, and can be detrimental to a dog’s overall health. While water is healthy, the consumption of too much of it indicates an underlying issue.

Frequent Urination

If your dog is suddenly going to the bathroom much more often or having accidents throughout the home, then he or she may have diabetes. This is usually an early symptom of diabetes, and owners who act quickly may be able to treat the disease without any serious complications.

Weight Gain

Diabetes can wreak havoc on our pets’ metabolic systems, and one of the first noticeable symptoms of diabetes in dogs is weight gain. Even if sudden obesity turns out not to be presenting as a symptom of diabetes in your dog, it can also put him or her at increased risk of developing it in the future. Because of this, it’s a good idea to address the issue of weight gain no matter what.

Unnecessary bouts of vomiting can be avoided in some cases, primarily by limiting your dog’s intake of food to small amounts throughout the day.


Diabetes is known to affect every organ and tissue in the body, and causes an immense amount of pain and inconvenience for our pets. If your dog’s eyes suddenly appear to be cloudy or foggy, they may be suffering from cataracts. While cataracts can form in older dogs’ eyes, diabetes is more often the underlying cause.

Sad Demeanour

Whenever more advanced stages of diabetes manifest, special fats and proteins in the liver begin to breakdown and release ketones. These ketones are poisonous to the body and can cause your dog’s mood to change quite rapidly. Any sort of depressed state that is observed alongside other symptoms on this list merits immediate evaluation by a specialist.

Augmented Appetite

Weight Loss

Diabetes can present itself in different dogs in different ways; some dogs will gain weight, while others lose it. Sudden weight loss in dogs that have had no major dietary changes means that the food is not being absorbed by the body in the way it should.


A tired, seemingly lazy dog is not a normal occurrence. Particularly in younger dogs, any signs of fatigue merit an evaluation by a licensed veterinarian to determine whether diabetes is the root cause.

Dull Coat

Diabetes drains the body of vital nutrients, which can affect your dog’s coat. A shiny coat is indicative of good health; a dull one lets us know that there is an underlying problem. If your dog has a good diet and still has a dull coat, then diabetes may be the cause.
