Dogs with diabetes have a significant and growingly prevalent illness that impairs their general health and well-being. Early symptom recognition is essential for effective disease management and your pet's long-term happiness and health.

Diabetes can cause serious side effects like cataracts, UTIs, and even potentially fatal diseases if it is not addressed. Recognizing these indications and pursuing immediate veterinary attention can greatly impact your dog's longevity and overall quality of life.


1. Excessive Thirst

Dogs that experience excessive thirst tend to drink a lot more water, often going back to their bowls and staying in to drink for long periods.

This results from the body trying to adjust for high blood sugar. When a person has diabetes, their body has trouble using glucose for energy, which leads to an accumulation of glucose in the blood, as a result, the kidneys then attempt to urinate out of this extra sugar.

The dog becomes more thirsty to replace lost fluids and stay hydrated, which sets off a vicious cycle of excessive drinking and peeing. It's important to see a vet if you observe such a shift in your dog's water intake so that you may properly diagnose and treat their diabetes and avoid any consequences.

2. Increased Urination

An increase in urine is one of the most obvious signs of diabetes in a dog. This happens as a result of the body's inability to control blood sugar levels. The kidneys can no longer reabsorb all of the glucose back into the bloodstream when blood sugar levels climb above a particular threshold.

The kidneys compensate by urinating more frequently and with a greater volume to get rid of the extra sugar. Larger urine puddles indoors, more frequent excursions outside to relieve oneself, or even accidents in previously housebroken canines are some symptoms of this.

It's critical to differentiate this from typical fluctuations in urination patterns since, in addition to diabetes, other underlying illnesses can also result in increased urination. For an accurate diagnosis and course of treatment, you must visit a vet if you observe a noticeable alteration in your dog's urinating patterns.

3. Weight Loss

Loss of weight in diabetic dogs who appear to be eating normally is one of the most alarming symptoms of the disease. This happens because of insulin resistance or insufficiency, which makes it difficult for the body to use glucose as fuel. Insulin operates as a key part of a healthy dog, enabling glucose to enter cells and power biological processes.

This key breaks down in people with diabetes, causing glucose to circulate in the bloodstream unutilized. When the body runs out of energy, it breaks down fat and muscle fibers to make fuel, which results in inexplicable weight loss.

This shows how crucial it is to keep an eye on your dog's weight in addition to their food consumption. A vet can evaluate the particulars of your dog's condition and suggest a course of action to control blood sugar and stop future weight loss.

4. Increased Appetite

The dog is more hungry even though it is eating more because its cells are starving for energy. Glucose cannot enter cells correctly in diabetics because either the body cannot produce enough insulin or it cannot use insulin adequately.

This raises blood sugar levels, but the cells still don't have their major energy source, so the dog eats more to try to meet its energy needs.

Dogs tend to lose weight while eating more food because their bodies begin to break down muscle and fat to make up for the lack of readily available glucose. It is essential to identify it in conjunction with other symptoms in order to diagnose and treat canine diabetes early on.

5. Lethargy or Fatigue

One of the most prevalent signs of diabetes in dogs is lethargy or exhaustion, which usually takes the form of a discernible decrease in energy and general activity. Dogs with diabetes may show signs of extreme fatigue or show reluctance to play or exercise as normal.

Insulin resistance or inadequate insulin production causes the body to not use glucose for energy as effectively, which results in less energy. Weakness and tiredness ensue from depriving muscles and organs of the fuel they require to perform at their best.

A dog's attitude and demeanor may also be impacted by this ongoing exhaustion; they may become more reclusive and less social. A vet's advice and close observation of these changes can aid in the early diagnosis and treatment of diabetes, thereby enhancing your dog's quality of life.

6. Cloudy Eyes

In dogs, cloudy eyes can be a major symptom of diabetes. High blood sugar levels brought on by diabetes can alter the lens of the eye, giving it a cloudy or milky look.

This disorder develops as a result of the bloodstream's excess glucose changing the lens's water balance, causing it to expand and turn opaque. In dogs with diabetes, cataracts can grow quickly, sometimes in a matter of weeks, and, if left untreated, can result in partial or total blindness.

Timely management can decrease the progression and improve results, thus early detection is essential. Maintaining blood sugar levels and scheduling routine veterinary examinations are crucial for preventing or lessening the effects of cataracts on your dog's vision.

7. Vulnerability to Other Health Problems

Dogs with diabetes frequently have weakened immune systems, which increases their susceptibility to a variety of secondary health problems. One prevalent issue is the emergence of urinary problems, as increased urine glucose levels foster the growth of germs.

In addition, diabetic dogs are more likely to acquire cataracts, which, if left untreated, can result in blindness or worse vision. A weakened immune system may also lead to delayed healing of wounds and a higher chance of skin infections.

Because diabetes is a chronic condition, it can put stress on vital organs like the kidneys and liver, which can result in severe issues like renal disease. Maintaining the general health and quality of life of diabetic dogs requires an understanding of and commitment to managing these vulnerabilities.

8. Sweet-Smelling Breath

A pleasant or fruity smell on a dog's breath is one warning sign of diabetes. A condition known as ketoacidosis, which happens when the body begins using fat for energy instead of glucose, is frequently the cause of this peculiar odor.

Ketones are created during the breakdown of fat and can build up in the bloodstream, giving off a distinct sweet fragrance in the dog's breath. Unmanaged diabetes can result in ketoacidosis, a serious and potentially fatal condition that has to be treated by a veterinarian right once.

In addition to sweet-smelling breath, other possible symptoms include nausea, fatigue, and fast breathing. For your diabetic dog to remain healthy and avoid serious health consequences, you must identify and treat ketoacidosis as soon as possible.

9. Vomiting

One of the most prominent signs of diabetes in dogs is vomiting, which can mean that the digestive tract is being affected by the illness. Insufficient insulin can cause a dog's body to be unable to control blood sugar levels, which can cause gastrointestinal distress and chronic or recurrent vomiting.

It happens when the body begins metabolizing fat for energy, resulting in the production of acidic ketones that build up in the circulation and induce nausea and vomiting.

It's critical to seek veterinarian care right away if your dog is vomiting frequently and exhibiting other symptoms of diabetes, such as increased thirst or weight loss, in order to control their health and stop further complications.

10. Diarrhea

Dogs with diabetes may get diarrhea for a variety of reasons. First of all, elevated blood sugar might result from uncontrolled diabetes. Diarrhea results from this upset stomach's natural fluid and electrolyte balance. Second, gastrointestinal problems are more common in dogs with diabetes.

Their intestines' high sugar content provides an ideal environment for bacterial development, which causes diarrhea and inflammation. Furthermore, diabetes-related nerve damage known as diabetic neuropathy can impact the mobility and function of the digestive tract, which may lead to loose stools.

Hence, it's important to remember that various underlying disorders can also cause diarrhea. Consequently, to identify the signs and symptoms of diabetes in dogs, veterinary diagnosis is crucial and soon begins the proper course of treatment.

11. Dehydration

In dogs with diabetes, dehydration can seem like a misleading sign even despite increased thirst. Thirst stimulates the consumption of fluids in healthy dogs, and adequate kidney function permits the reabsorption of water. Dogs with diabetes, however, encounter a malfunction in this mechanism.

When the body is unable to properly use the extra glucose, it is excreted through urine. Despite consuming more water, this loss of glucose drags fluids with it, leading to dehydration.

Dehydration should be detected early since it can worsen other diabetic problems. Using skin elasticity testing and blood work, veterinarians evaluate the patient's level of hydration. Based on these findings, intravenous fluids and modifications to diabetic care programs are recommended.

12. Poor Appetite

Although diabetes is frequently linked to increased hunger, some diabetic dogs may have decreased appetite. Given that the body is still having difficulty converting food into usable energy, this may seem strange, and hormonal imbalance is the main cause of this.

In healthy dogs, insulin opens up cells so that food's glucose, or sugar, may enter and power the body. This process is hampered in dogs with diabetes, which raises blood sugar levels. However, because there isn't any usable glucose in the cells, the body feels as though it is lacking energy.

Despite the underlying need for energy, this can occasionally result in a decreased interest in food. This is one of the most complicated symptoms of dogs with diabetes, such as nausea or upset stomach, which can also reduce appetite.

13. Difficulty Walking

A worrying signs dog has diabetes is difficulty walking. This is a result of a problem called diabetic neuropathy. A dog with diabetes has trouble getting the right amount of energy from their blood sugar. Nerves, especially those in the legs, may be impacted by this deficit.

Walking might be difficult due to discomfort, weakness, and incoordination caused by damaged nerves. The dog may have a wobbly walk, appear stiff, stumble more frequently, or have trouble getting up.

Since this problem may get worse over time, it's critical to see a veterinarian as soon as you notice any changes in your dog's movement. By preventing or delaying the onset of nerve damage, early detection and treatment of diabetes can help your dog live an active and pleasant life.

14. Incontinence

For diabetic dogs and their owners, incontinence, the inability to control urination can be a stressful symptom. This loss of control over one's bladder is frequently the result of two interrelated events. First, diabetic dog signs of increased thirst and urination might exceed the bladder's capacity and cause leakage.

Second, diabetes may harm the nerves that transmit the urge to urinate or cause the muscles in the bladder to contract. This nerve injury may make it more difficult for the dog to detect when its bladder is full or to stop it from urinating against its will.

Although incontinence might be an annoying symptom, it's important to keep in mind that it's a treatable indication of an underlying illness. It's crucial to see a veterinarian as soon as you see your dog having incontinence to properly diagnose and manage their diabetes.

15. Labored Breathing

This happens as a result of diabetes impairing the body's capacity to properly metabolize sugar. Normally, sugar is transformed into energy for the body's processes, such as breathing.

This conversion process is compromised in dogs with diabetes, which results in insufficient energy for essential organs. The organs in charge of gas exchange, the lungs, are most impacted.

Breathing becomes difficult for the dog as a result of the respiratory system having to work harder to make up for the energy shortage. This may seem like difficulty breathing in and out, quick, shallow breathing, or excessive panting.

See a veterinarian right away if you observe any changes in your dog's breathing habits, particularly when they are sleeping. This problem can be avoided and your pet will get the oxygen it needs for optimum health if diabetes is detected and treated early.
