Diabetes mellitus in dog is a disease in which the body does not produce enough insulin (the hormone that controls how the body and cells absorb and use sugar). the disease occurs in between .13% and .64% of dogs. Some breeds have higher risk factors including:
- Australian Terriers
When the body does not produce enough insulin, the body is deprived of energy causing it to look for other sources such as the fat stored in the body. Since absorption and the break down of these fats isn't that efficient, acid and fat levels increase in the blood causing a condition called canine ketoacidosis. This break down of fats causes the weight loss associated with the condition. Since the body is craving nutrition, appetite increases. Glucose or sugar in the blood spills into the urine triggering a thirst response and the need for more urination.
Untreated, diabetes can cause life-threatening complications such as:
- Long-term weight loss
- Hepatic lipidosis (fatty liver)
- Ketoacidosis (caused by uncontrolled diabetes where the body isn't correctly breaking down proteins and fats. The blood compounds are called ketones)
- Bacterial urinary tract infections
It is important to provide the proper care for dogs and pets. With treatment, dogs can lead normal, happy lives.
Signs and Symptoms
Symptoms of diabetes mellitus in dog include:
- Excessive thirst (your dog
will drink more water than usual)
- Increased need to urinate (your housebroken dog may begin to have accidents in the house)
- Weight loss
Other symptoms in more severe cases can include anorexia, lethargy, vomiting, and diarrhea. Blinding can occur in dogs starting to experience the formation of cataracts.

Diagnosis of Diabetes Mellitus in Dogs
There are no physical signs in healthy dogs. Patients can be
overweight while others can be thin.
Your vet will do a blood test to check your dog's blood sugar and will also test his urine. Your vet may want to do these tests when your dog has been fasting (not eating) for 12 hours or so. The vet will also look for signs of dehydration and electrolyte problems.
He or she will also look for signs of advanced stages of the disease, a condition called canine ketoacidosis. Typical symptoms include the abdominal pain, vomiting and diarrhea.
Some diseases have similar symptoms and need to be ruled out when diagnosing diabetes in dogs. These include:
- Chronic kidney disease
- Pheochromocytoma (adrenal gland tumor)
In healthy dogs, treatment can be managed as an outpatient, such as cases where ketonuria is found in the blood (improperly digested nutrients). For cases of chronic KDA (diabetic keoacidosis) in patient treatment is required.
There is no cure for diabetes in dogs. Treatment for type I diabetes involves daily insulin injections. While there are some oral medications to treat diabetes in humans, there are no oral medications for diabetes in dogs. If a dog is chronically ill, then a short-acting insulin is used to reduce the risk of hypoglycemia (low levels of glucose in the blood). Once the dog is stabilized, longer lasting insulin is used.
Your vet will show you how to give your dog insulin injections and tell you when to give them. Give him his medication at the same time every day. It may or may not be necessary for you to check your dog's blood glucose levels at home (called BGC's). If it is necessary, your vet will show you how to do it as well.

Patients will be monitored every 12 hours for insulin levels until the patient is stable. A veterinarian may also take measurements of Fructosamine in 2 to 3 weeks.
Feed your dog at the same time every day. He should eat the same amount of food each day, as well. It is generally recommended that you feed your dog twice a day to keep his blood sugar levels even. Feed him a commercial dog food and do not give him table scraps. If your dog is overweight it will be harder to control his blood sugar levels, so talk to your vet about how to help him lose weight if needed.
Your dog needs regular exercise and it will be important for him to get about the same amount of exercise each day because the amount of exercise he gets affects the amount of insulin his body requires. That means if he exercises a lot one day and not at all another day, he will need different amounts of insulin. Unless you are monitoring his blood glucose level and adjusting his insulin dose accordingly, this could spell trouble for your dog.

Dog Diabetes Diet
The goal of any diet is to reduce any changes in blood glucose levels after eating. Most research supports the use of a fiber-rich diet of the patient is overweight or if the diabetes is challenging to control with medications. Goals are to achieve the right balance of:
Diets are usually not changed during the process where a veterinarian
is working to stabilize the patient. Diets should also be
attractive to the dog to encourage eating.
Work with your veterinarian or veterinary nutritionist to find the right diabetes diet for your dog. Diets not only need to be nutritionally smart, but also that get your dog to enjoy eating. Also know that diet can impact insulin levels, so consult with your veterinarian when moving to a new diet so that blood glucose levels can be monitored during the change. Shifts in diet can cause the need for increases or decreases in levels of prescribed medications.
Over weight dogs should be brought into normal weight levels since being overweight creates some insulin resistance.
Natural Medicine for Dogs with Diabetes
There are no recognized alternatives to insulin treatment. That said, there is some evidence that suggests that the use of carefully chosen herbal remedies and dietary supplements can help to both prevent diabetes and to keep it under control in dogs who have already developed it. A good commercial source for more research is PetAlive GlucoEnsure. If you go this route, work with your veterinarian to monitor progress or changes in your dogs condition.
A visit to a veterinarian along with required tests can cost from $101
to $500 (US Dollars). The diagnosis of more complicated cases can range
from $501 to more than $1000 (US Dollars).
Treatment and follow up care for cases where there are no other complicating diseases or factors can range from $101 to $500 (US Dollars). Complicated cases can cost $251 to more than $1000.
Dogs that are monitored and treated can do well for years.
There are no confirmed ways to prevent diabetes mellitus in dogs. Some
risk factors can be reduced including:
- Lack of exercise
