How is pituitary insufficiency diagnosed?

The vet will typically begin with a physical examination and blood and urine biochemistry panels. Brain imaging (CT/MRI) or specialist endocrine testing may be arranged as needed to determine the underlying cause.

How often will blood tests be needed after diagnosis?

Follow-up frequency depends on the individual case and medication used. In the early stages, checks are often scheduled every few weeks to months; once stable, visits may be reduced to every few months. Follow your vet's specific guidance.

What at-home care can help the skin recover?

As directed by your vet, use gentle moisturising and cleansing products, avoid frequent bathing, maintain a consistent diet, and attend regular follow-up appointments.

If my pet only has mild hair loss, does it need emergency care?

Mild hair loss without changes in alertness or appetite can be monitored at home with a log. If hair loss spreads or changes in behaviour or eating occur, see a vet promptly.

How much do the tests and treatment usually cost?

Costs vary by clinic and region — ask your vet for an estimate before proceeding.

Pituitary Insufficiency in Dogs & Cats: Hair Loss, Metabolism & Long-Term Care [2025]

Pituitary insufficiency causes multiple hormone deficiencies; in young dogs it may present as pituitary dwarfism. Signs include growth retardation and abnormal coat. Treatment focuses on hormone replacement and is usually lifelong.

Schedule a clinic visit as soon as possible (within 24-72 hours)

•Symmetrical hair loss continues to expand noticeably
•Marked change in appetite or short-term weight loss
•Reduced activity, daytime sleepiness, or changes in mental state

01What symptoms indicate a problem?

Changes in coat and skin are the primary signs, often accompanied by metabolic or behavioural changes; the progression is usually gradual.

Progressive hair loss, often distributed symmetrically
Skin thinning, pigmentation or texture changes, prone to dryness or fragility
Changes in appetite or noticeable weight gain or loss over a short period
Decreased activity, lethargy, or changes in mental alertness
If symptoms persist or worsen, schedule a clinic visit promptly

Seek emergency care immediately if you notice the following symptoms:

⚠️ Persistent seizures or loss of consciousness require immediate veterinary attention
⚠️ Severe dehydration or prolonged inability to eat requires emergency evaluation

02How to assess at home? Key observations and when to go to the emergency vet

Systematically tracking coat, skin, and behavioural changes at home helps your vet make a thorough assessment.

Take regular photos with your phone to document hair loss and skin changes and build a log
Weigh your pet daily or regularly and record the trend for easy comparison
Track changes in appetite, water intake, and urination/defecation frequency
Observe changes in energy level and alertness at different times of day
If symptoms continue to worsen, find a clinic that offers endocrine testing and arrange an examination

03How will the vet diagnose this? Common diagnostic tests

At the clinic the vet will start with a physical examination and combine blood, urine, and imaging tests for a comprehensive evaluation.

Physical examination

evaluation of skin, coat, body weight, and overall condition

Blood and biochemistry panels

assessment of endocrine and metabolic markers

Urinalysis

assessment of kidney function and possible metabolic abnormalities

Imaging

X-ray, CT, or MRI to evaluate the brain and other organs

Referral to an endocrinology or specialist centre for further evaluation and treatment planning if needed

04How is it treated and managed after diagnosis? Medication, diet, and care guide

Treatment typically involves long-term monitoring and supportive care, individualised according to the pet's condition and test results.

Once diagnosed, medication or supportive therapy will be tailored to the individual case
Adjust diet as directed, and monitor with regular weigh-ins and blood tests to track treatment response
Provide extra skin care at home; avoid harsh shampoos and excessive bathing
Attend scheduled follow-up appointments to monitor progress and review test results
If the condition changes or is poorly controlled, consider consulting or referring to a specialist clinic

05What to prepare before the vet visit? Key information to help your vet work faster

Bring a log noting when symptoms started and how they have changed

Prepare diary entries on appetite, water intake, and elimination, along with weight records

List all current medications, supplements, and skin-care products

Bring photos or videos showing the progression of hair loss and skin changes for comparison

If you have previous test reports or imaging, bring them to the appointment
