Symptoms of Diabetes in Dogs – Everything You Need to Know

Updated: June 4, 2023


Diabetes is a complex metabolic disorder that can affect not only humans but also our beloved canine companions. Like humans, dogs can develop diabetes, and it’s important for pet owners to be aware of the symptoms to ensure early detection and proper treatment. One of the primary symptoms of diabetes in dogs is increased thirst and urination. If you notice that your dog is drinking more water than usual and having more frequent trips to relieve themselves, it could be a sign of diabetes. This excessive thirst and urination occur due to the high levels of glucose in the bloodstream, which the body tries to eliminate through urine.

Another common symptom is increased hunger coupled with weight loss. Dogs with diabetes may appear ravenous and constantly seek food, yet they may lose weight despite eating more. This happens because the body is unable to properly utilize glucose for energy, leading to a state of chronic hunger and subsequent weight loss. Lethargy and decreased activity levels can also be indicative of diabetes in dogs. A diabetic dog may appear less energetic and have a reduced desire to engage in physical activities or play. This lack of energy stems from the body’s inability to properly regulate blood sugar levels and convert glucose into energy.

Other signs to watch for include recurrent urinary tract infections, chronic skin infections, and slow-healing wounds. Diabetes compromises the immune system, making dogs more susceptible to infections. These infections can occur in various parts of the body, such as the urinary tract or the skin. Additionally, if you notice that your dog’s cuts or wounds take longer to heal than usual, it may be a result of poor blood circulation and impaired healing processes associated with diabetes.

If you observe any of these symptoms in your dog, it’s crucial to consult a veterinarian promptly. Early diagnosis and management of diabetes can significantly improve your dog’s quality of life. Your vet will perform tests to determine the blood glucose levels and may recommend dietary changes, insulin therapy, or other treatments tailored to your dog’s specific needs. With proper care and monitoring, diabetic dogs can lead happy and healthy lives alongside their loving owners.

1 Understanding Canine Diabetes

Canine diabetes is a chronic metabolic disorder characterized by high blood sugar levels in dogs. It can be classified into two main types: type 1 and type 2 diabetes. Type 1 diabetes occurs when the pancreas fails to produce sufficient insulin, while type 2 diabetes results from insulin resistance or inadequate insulin production. While type 1 diabetes is relatively rare in dogs, type 2 diabetes is more common, particularly in middle-aged and older dogs.

Several risk factors contribute to the development of diabetes in dogs. Obesity is a significant risk factor, as excess body fat can lead to insulin resistance. Certain breeds, such as Poodles, Dachshunds, Beagles, and Miniature Schnauzers, are more prone to developing diabetes, suggesting a genetic predisposition. Age and pancreatitis, inflammation of the pancreas, also increase the risk.

Diabetes can have a profound impact on a dog’s health if left untreated or poorly managed. Dogs with diabetes experience increased thirst and urination due to the body’s attempts to eliminate excess glucose. Despite an increased appetite, they may lose weight as the body breaks down stored fats and proteins for energy. Cataracts, neuropathy (nerve damage), increased infection susceptibility, and other complications can arise from prolonged elevated blood sugar levels.

1.1 Definition and Types of Diabetes

Diabetes mellitus, commonly known as diabetes, is a chronic metabolic disorder characterized by high blood sugar levels due to either insufficient insulin production or ineffective utilization of insulin. Insulin is a hormone produced by the pancreas that regulates the metabolism of carbohydrates, fats, and proteins in the body.

There are two main types of diabetes in dogs:

Type 1 diabetes occurs when the pancreas fails to produce enough insulin. This can be due to immune-mediated destruction of the insulin-producing cells in the pancreas or other factors that impair insulin production. Type 1 diabetes is relatively rare in dogs.

Type 2 diabetes occurs when the body becomes resistant to the effects of insulin or when the pancreas does not produce enough insulin to meet the body’s needs. It is the most common form of diabetes in dogs. Obesity, genetic predisposition, and certain medications can contribute to the development of type

1.2 Prevalence and Risk Factors

The exact prevalence of diabetes in dogs is not well established, but it is believed to be relatively common, especially in middle-aged and older dogs. Some dog breeds, such as Poodles, Dachshunds, Beagles, and Miniature Schnauzers, are considered to be at higher risk for developing diabetes. Female dogs are also more commonly affected than males.

Other risk factors for canine diabetes include:

Obesity is a significant risk factor for the development of type 2 diabetes in dogs. Excess body fat can lead to insulin resistance, where the body’s cells do not respond properly to insulin.

Middle-aged and older dogs are more susceptible to developing diabetes. This is believed to be due to age-related changes in the pancreas and increased insulin resistance. Certain dog breeds have a higher genetic predisposition to developing diabetes, suggesting a hereditary component to the disease. Inflammation of the pancreas, known as pancreatitis, can damage the insulin-producing cells and increase the risk of diabetes.

1.3 Impact of Diabetes on Dogs’ Health

Diabetes can have significant health implications for dogs if not properly managed. The elevated blood sugar levels associated with diabetes can lead to various complications, including:

Dogs with diabetes tend to produce large volumes of urine (polyuria) and have increased thirst (polydipsia) as their bodies try to eliminate excess glucose through urine. This can result in more frequent urination and increased water consumption.

Despite an increased appetite, dogs with diabetes may experience weight loss due to the inability of cells to utilize glucose properly. The body starts breaking down stored fats and proteins to provide energy. Cataracts, characterized by clouding of the lens of the eye, can develop in dogs with poorly controlled diabetes. Cataracts can lead to impaired vision or even blindness if left untreated.

Long-standing diabetes can cause damage to the nerves, resulting in a condition called diabetic neuropathy. This can lead to weakness, muscle wasting, and coordination problems in dogs. Elevated blood sugar levels can impair the immune system’s functioning, making dogs with diabetes more susceptible to infections, particularly urinary tract infections and skin infections. It is essential for dog owners to recognize the signs of diabetes, such as increased thirst, frequent urination, weight loss,
