Hormone Disorder Testing for Cats and Dogs
Some skin, coat and ear conditions in pets can be caused or worsened by underlying hormonal imbalances. When clinical signs or a history of recurring issues suggest an endocrine cause, we may recommend targeted testing to support accurate diagnosis and effective treatment planning.
When Is Hormone Disorder Testing Recommended?
Hormone disorder testing is typically recommended for dogs and cats with skin, coat or ear conditions that are persistent, recurrent or not responding as expected to routine treatment. It is most often considered when the pattern of disease suggests an underlying systemic or endocrine cause rather than a primary skin condition.
This may include pets showing signs such as:
- hair loss or coat changes in dogs or hair loss or overgrooming in cats
- ongoing skin redness, irritation or rash in dogs or scabs, sores or skin lesions in cats
- recurrent ear problems or ear infections in dogs or ear problems, irritation or discharge in cats
- chronic or recurring skin infections, particularly when response to treatment is incomplete or short-lived
In many cases, these signs are associated with conditions such as:
- skin infections in dogs or skin infections in cats
- ear disease in dogs or ear disease in cats
- endocrine disorders such as hypothyroidism or Cushing’s disease, which can affect skin, coat and immune function.
- Other endocrine or systemic conditions may also be considered where clinically appropriate.
Hormone disorder testing helps identify underlying systemic causes of dermatological disease, allowing treatment to focus on correcting the hormonal imbalance rather than managing skin signs alone.
What Testing Involves
Hormone disorder testing focuses on identifying imbalances that may be contributing to ongoing dermatological disease. Testing typically involves bloodwork, urinalysis and, in some cases, imaging or skin biopsies.
The tests used may assess thyroid function, adrenal activity and other hormone levels known to affect skin health. Results are always interpreted alongside your pet’s clinical signs, history and previous treatment response.
Common hormonal conditions we assess include:
- Hypothyroidism: Most commonly seen in middle-aged dogs, hypothyroidism may present with hair thinning, recurrent infections, greasy or flaky skin, and changes in coat quality. Diagnosis involves measuring total T4, free T4 and thyroid-stimulating hormone, interpreted in the context of clinical signs.
- Cushing’s disease (hyperadrenocorticism): Caused by excess cortisol production, Cushing’s disease may lead to hair loss, fragile skin, slow healing, and repeated skin or ear infections. Diagnosis typically involves specialised endocrine testing such as ACTH stimulation or low-dose dexamethasone suppression testing, often supported by routine bloodwork and, where appropriate, imaging.
Confirming a hormonal disorder allows treatment to be directed at the underlying cause rather than managing skin symptoms alone. Where required, we work closely with your regular veterinarian to develop a coordinated treatment plan that supports both skin health and overall wellbeing.

Testing and Treatment
Targeted Testing
Hormone testing may be recommended based on your pet’s history, clinical signs and response to previous treatments. Tests are selected to investigate the most likely hormonal contributors rather than screening unnecessarily.
Interpreting Results
Hormone levels are interpreted alongside clinical findings rather than in isolation. This helps avoid misdiagnosis and ensures results are meaningful for your pet’s individual presentation.
Treatment Planning
Identifying a hormonal disorder allows treatment to address the underlying cause of skin disease. Where required, we work with your regular veterinarian to develop a coordinated management plan that supports long-term skin health and overall wellbeing.
Ongoing Care and Management
Managing a hormonal disorder is a long-term process that focuses on your pet’s overall health as well as their skin and coat. Treatment plans are tailored to your pet and may include medications, dietary adjustments, and regular monitoring of hormone levels.
We provide clear instructions and support to help you administer treatments at home, track your pet’s progress, and recognise any changes that may require attention. Follow-up testing is usually scheduled to ensure the treatment is effective and your pet remains comfortable and healthy.
Our team works with your regular veterinarian to coordinate ongoing care, adjust treatment as needed, and maintain long-term skin and overall wellbeing. With careful monitoring and proactive management, many pets experience significant improvement in skin health, coat quality, and overall quality of life.

Frequently Asked Questions
How do I prepare my pet for hormone testing?
Most tests require your pet to fast for a few hours beforehand. We will provide specific instructions prior to your testing appointment to help ensure accurate results.
How long will it take to get results?
Some routine tests are ready within a few days, while specialised endocrine tests may take longer. We will explain expected timeframes during your appointment and discuss any recommended next steps for your pet’s care.
How soon can treatment begin if a disorder is found?
Treatment can usually start as soon as the results are confirmed.
Do hormonal disorders only affect the skin?
No. Hormonal imbalances can influence energy, weight, appetite, and overall wellbeing, which is why we take a holistic approach and work closely with your regular veterinarian.
