Endocrine Disorders in Dogs: Symptoms and Treatment

Endocrine disorders mainly occur in older dogs. Such conditions require special attention and quality treatment. At our veterinary clinic, Haabersti Loomaklinik, in Tallinn, we offer diagnostics for various animal disorders, conduct analyses, and provide comprehensive treatment.

Hypothyroidism in Dogs: Causes, Symptoms, and Treatment

Iatrogenic hypothyroidism is a relatively common thyroid gland disorder, resulting in a significant decrease in T4 hormone levels. The average age of onset is 7 years. Breeds predisposed to the disease include large breeds like Golden Retrievers, Dobermans, German Shepherds, Irish Setters, and small breeds like Cocker Spaniels, Miniature Schnauzers, Dachshunds, and Poodles. However, it’s essential to note that hypothyroidism can occur in any middle-aged animal.

Causes of hypothyroidism:

1. Thyroid or hypothalamus neoplasia.
2. Infections.
3. Iodine deficiency.
4. Medications.


1. Lethargy (they become more lethargic and sad).
2. Weight gain.
3. Appearance of symmetrical alopecia.
4. Skin inflammation.

Treatment involves medicinally increasing the T4 hormone levels. Hormone replacement therapy is lifelong and requires periodic monitoring (initially, T4 levels are monitored 4-6 weeks after the start of therapy to confirm treatment effectiveness, and then repeated every six months). Improvements are noticeable and occur quite rapidly: clinical recovery takes about 3 months. Animals become active, alopecia gradually disappears, skin and coat quality significantly improve, and weight returns to normal.

Cushing’s Disease in Dogs

Cushing’s in dogs is a chronic disorder associated with an excess of cortisol hormone in the body. It might be dangerous if left untreated.


  • Increased appetite.
  • Abdominal enlargement.
  • Hair loss.
  • Weakened immune system

To precisely diagnose Cushing’s disease in dogs, blood tests and additional investigations such as ultrasound and computerized tomography are conducted. These additional methods enable the veterinary specialist to accurately determine the cause of the disease and develop an individual treatment plan for each pet.

Cushing’s disease in puppies and dogs may sometimes require surgical treatment aimed at removing adrenal gland tumors. Additionally, therapy may involve the use of medication.

Canine Diabetes Mellitus

Diabetes mellitus (hyperglycaemia) in dogs is characterized by insufficient insulin hormone secretion or improper utilization, leading to increased blood sugar levels.

Syndromes may include:

1. Frequent urination.
2. Increased thirst.
3. Weight loss.
4. General weakness.
To control blood glucose levels and provide medical care, regular insulin injections are administered. Dog diabetes treatment with these disorders requires a comprehensive approach. Our clinic offers options of individual treatment plans, including necessary medications, dietary recommendations, and pet care. It is important to remember that treating immune system disorders requires constant observation and monitoring by a veterinary specialist.

The cost of treating endocrine disorders in dogs depends on several factors, including the chosen diagnostic methods and medications. In our Tallinn clinic, reasonable prices are available for services related to the diagnosis and treatment of endocrine disorders, including canine diabetes in a dog.

If you notice signs of internal organ impairment in your beloved companion, it is recommended to consult a veterinary specialist to determine the causes and begin preventive measures. Our clinic provides high-quality care and attention to your pet’s individual needs. We are ready to provide the necessary support in case of problems and answer any questions regarding endocrine pathologies.
