Managing your dog's diabetes requires a good understanding of blood sugar levels. A normal blood glucose level for dogs is between 60-120 milligrams per deciliter (mg/dL).

Dogs with diabetes typically have high blood sugar levels, often above 200 mg/dL. This is because their bodies don't produce enough insulin to regulate blood sugar.

Your veterinarian will likely take a blood sample to determine your dog's baseline blood sugar level. This will help you understand how their levels change throughout the day.

Blood sugar levels can fluctuate throughout the day, even in dogs with diabetes. This is why regular monitoring is crucial to maintaining your dog's health.

What Is Diabetes in Dogs?

Diabetes in dogs is a common endocrine disorder that affects the way their body regulates blood sugar levels.

It's caused by a lack of insulin production or an inability to use insulin effectively, leading to high blood sugar levels.

Dogs with diabetes typically have a higher-than-normal blood glucose level, which can damage their organs and tissues over time.

Their pancreas, which normally produces insulin, is unable to keep up with their body's needs, resulting in high blood sugar levels.

Symptoms can include increased thirst and urination, weight loss, and blurred vision.

Dogs with diabetes may also experience vomiting, diarrhea, and lethargy.

High blood sugar levels can damage their kidneys, eyes, and nerves, leading to serious health complications.

Their lifespan can be significantly reduced if left untreated or poorly managed.

A diagnosis of diabetes is typically made through a combination of physical examination, laboratory tests, and medical history.

Causes and Types

Diabetes in dogs primarily manifests in two forms: Insulin-deficiency diabetes (IDD) or type 1, where the body doesn't produce enough insulin, and insulin-resistance diabetes (IRD) or type 2, where the body produces insulin but loses its ability to utilize it effectively over time.

IDD is more common in dogs, while IRD is often linked to conditions like obesity and Cushing's disease, which can be a result of genetic factors and environmental triggers. Certain breeds, overweight dogs, or those with hormonal and metabolic disorders are at a higher risk.

Here are some common causes of diabetes in dogs:

  • Genetic predisposition
  • Infection
  • Drugs
  • Obesity
  • Immune-mediated disease
  • Pancreatitis

Female dogs are affected approximately twice as often as males, and certain breeds are also more susceptible, such as Australian Terriers, Schnauzers, Cavalier King Charles Spaniels, Labradors, Golden Retrievers, Dachshunds, Poodles, and Pugs.

What Is Mellitus?

Mellitus is a type of diabetes that affects dogs, and it's characterized by a high blood sugar level that can't be controlled on its own.

The pancreas is unable to secrete enough insulin, or the cells have become resistant to insulin, leading to this condition.

Diabetes mellitus is almost exclusively Type 1 insulin-dependent diabetes mellitus (IDDM) in dogs, meaning they can't be treated with diet or oral drugs alone.

Regular injections of insulin are necessary to maintain their blood glucose levels.

Female dogs are affected approximately twice as often as males, and certain breeds are more susceptible, such as Australian Terriers and Schnauzers.

Certain breeds, overweight dogs, or those with hormonal and metabolic disorders such as Cushing's Disease, are at a higher risk of developing diabetes.

Your vet will conduct tests to determine the type of diabetes affecting your dog.

The exact cause of diabetes in dogs can be complex and often a combination of genetic factors and environmental triggers.

Diabetes in dogs is almost exclusively Type 1 insulin-dependent diabetes mellitus (IDDM) and cannot be treated purely with diet or oral drugs.

Here are some common causes of diabetes in dogs:

  • Genetic predisposition
  • Obesity
  • Immune-mediated disease
  • Pancreatitis
  • Drugs
  • Infection

Diabetes in dogs is usually diagnosed between the ages of 4 and 14 years, with most dogs diagnosed between 7 and 9 years of age.

Symptoms and Diagnosis

Symptoms of high blood sugar levels in dogs can be a real challenge to recognize, but early detection is key. Excessive thirst and urination are common early signs, as your dog's body tries to flush out excess glucose.

Increased appetite and weight loss despite eating more can also be indicators. Some dogs may even become more lethargic or inactive, while others might display restlessness, especially at night.

Here are some common symptoms to look out for:

  • Increased thirst (polydipsia)
  • Increased urination (polyuria)
  • Increased appetite (polyphagia)
  • Weight loss
  • Eye cataracts
  • Urinary tract infection

A thorough physical examination and review of your dog's medical history are usually the first steps in diagnosing diabetes. Your veterinarian may also perform blood and urine tests to check for high glucose levels and rule out other conditions.

Recognizing Symptoms

Recognizing symptoms of diabetes in dogs is crucial for early detection and effective management. Excessive thirst and urination are common early signs, often accompanied by weight loss despite increased appetite.

A diabetic dog may become more lethargic or inactive, showing increased appetite or restlessness, particularly at night. Changes in elimination habits can be an early sign, such as unusual accidents in the house.

If left untreated, diabetes in dogs can progress rapidly, leading to symptoms like loss of appetite, lethargy, urinary tract infections, and skin infections. Long-term, unregulated diabetes can cause health complications like cataracts, seizures, kidney failure, and an enlarged liver.

Some common clinical signs of diabetes include increased thirst (polydipsia), increased urination (polyuria), increased appetite (polyphagia), weight loss, eye cataracts, and urinary tract infections.

Here are some key symptoms to look out for:

  • Marked increase in urination
  • Excessive thirst
  • Increase or decrease in appetite
  • Breath that smells “sweet”
  • Lack of energy
  • Unexplained weight loss

Regular check-ups with your veterinarian, along with consistent monitoring and proper management at home, can help keep diabetes under control.

Spotting the Difference

Diabetes in dogs can be a bit tricky to diagnose, but there are some key differences between canine and human diabetes.

Diabetes in dogs is usually similar to Type 1 diabetes in humans, where the body fails to produce sufficient insulin. This is in contrast to Type 2 diabetes, which is the most common form in humans, where the body still produces insulin but uses it inefficiently.

Some common clinical signs that indicate diabetes in dogs include increased thirst, increased urination, increased appetite, weight loss, eye cataracts, and urinary tract infections.

Here are some key differences between canine and human diabetes:

It's essential to keep in mind that diabetes in both dogs and humans is manageable, and with proper care and attention, your furry friend can lead a happy and healthy life.

How Is Diagnosed?

Diagnosing diabetes in dogs involves a thorough physical examination and review of the dog's medical history. The most common symptoms that may trigger a veterinarian to suspect diabetes include increased thirst, urination, and weight loss.

A baseline bloodwork test, which includes a CBC and Blood Chemistry, is the fundamental diagnostic test. This test checks various factors, especially the persistent elevation of blood glucose levels.

Consistently elevated blood glucose levels indicate diabetes, while a one-off high reading may be due to stress or other temporary factors.

Your veterinarian will also check the urine test results for glucose levels and bacteria growth. High glucose levels in the urine can indicate diabetes, and bacteria growth may indicate a urinary tract infection.

An abdominal ultrasound may be performed to rule out concurrent pancreatitis. This test can help your veterinarian make a clear diagnosis.

The results of the blood test, including the fructosamine level, will also be examined to look at the average blood glucose level over the last three weeks.

The results of the urine test will be examined for bacteria growing in the urine, which will be treated by antibiotics if a urinary tract infection is present.

An abdominal ultrasound will be performed to rule out concurrent pancreatitis.

The most important facet of managing diabetes mellitus is good communication with the owner, as owners need to realize the variables involved with treatment and the money and time commitment required.

Here are some questions and concerns that owners should consider when managing their dog's diabetes mellitus:

  • What is the patient's home feeding schedule?
  • What diet and how much of it is fed at each meal? Are any treats given (be specific)?
  • Are there other pets in the household? If so, can they be separated from the patient at meal time?
  • Is the owner able to administer insulin injections? Is he or she willing to learn?
  • Does the patient need to lose weight? Gain weight? Neither?
  • Is the owner able to perform glucose curves at home? If so, recommend purchasing a quality glucometer that is reliable in dogs (e.g., AlphaTRAK 2).

Hypoglycemia

Hypoglycemia can be a serious condition that requires prompt treatment.

A hypoglycemic episode typically starts with lethargy and weakness, and can progress to disorientation and even seizures if left untreated.

Feeding a meal can help treat a hypoglycemic episode, or you can apply a syrup to the buccal membranes for quick relief.

With more advanced levels of hypoglycemia, emergency intervention using intravenous 50% dextrose may be necessary.

Treatment and Management

Dogs receiving insulin should be fed twice daily, with the daily caloric intake divided into 2 equal meals. A small snack calculated into the daily caloric requirements may be given at peak insulin activity time, usually 4 to 8 hours after insulin administration.

To determine how much of the selected diet to feed, the patient's daily kilocalorie requirement must first be calculated. The patient's body condition score is then used to choose the appropriate energy factor needed to determine metabolic energy requirement (MER). The MER factor can range from 0.8 to 2 depending on whether the patient needs to lose, gain or maintain weight.

Here are some basic considerations when choosing a diet for a diabetic dog:

Keeping a Dog Healthy

Providing a balanced diet is crucial for your dog's overall health, especially if they have diabetes.

A lean dog is a healthy dog, so make sure your furry friend isn't overweight. Losing a few pounds can help their cells use insulin more efficiently.

When managing diabetes mellitus (DM) in dogs, veterinary practitioners have more relaxed target blood glucose ranges compared to human patients. This is because dogs don't experience the same long-term effects of hyperglycemia as people do.

Veterinary practitioners should still be vigilant in monitoring for potential complications, such as urinary tract infections, pancreatitis, and other endocrinopathies like hyperadrenocorticism.

With proper veterinary care and client commitment, dogs with DM can live a full and healthy life, even if they have other complicating diseases.

Frequently Asked Questions

What is a dangerously high blood sugar for a dog?

For dogs, a blood sugar level above 400 mg/dl (22 mmol/L) is considered a medical emergency. If your dog's blood sugar is this high, seek veterinary care immediately to prevent serious complications.

Is 20 units of insulin a lot for a dog?

The dosage of 20 units of insulin for a 50-pound dog is relatively standard, but the type of insulin and its concentration (U-40 or U-100) play a crucial role in determining the correct dosage. If you're unsure about your dog's insulin needs, consult with a veterinarian for personalized guidance.

How to lower dog blood sugar quickly?
