When should gluten-sensitive enteropathy be suspected?

If your pet has recurrent diarrhoea, weight loss, or changes in appetite that do not respond well to routine treatment, a vet may consider gluten-related enteropathy and recommend further testing. Consult your vet for confirmation.

What tests will the vet perform at the appointment?

Common tests include blood and stool analysis, imaging assessment, and endoscopic biopsy when needed to clarify intestinal tissue changes. Results guide treatment decisions and follow-up frequency.

Does treatment require a long-term diet change?

Most cases are managed primarily with a long-term gluten-free or hypoallergenic diet, but the specific dietary adjustments and whether they need to be lifelong depend on the vet's assessment and follow-up findings. Follow your vet's advice.

How often are follow-up visits recommended?

In the early stages, follow-up visits are typically scheduled every few weeks to months to assess symptoms and weight. Once stable, the interval can be extended. Your vet will determine the actual frequency based on your pet's condition and test results.

How much do the tests and treatment usually cost?

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

When to See a Vet

Seek immediate veterinary care (emergency)

•Persistent vomiting with inability to maintain hydration on their own
•Persistent large amounts of bright red blood in the stool or black stool
•Rapid, noticeable weight loss with weakness and lethargy

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

•Repeated diarrhea or persistent loose stool that is not improving
•Marked decrease in appetite or reduced food intake
•Mucus or blood in the stool, even if energy level is still acceptable

01What symptoms indicate a problem?

Gluten-related enteropathy in Irish Setters (also seen in other breeds and cats) typically presents as recurrent or chronic diarrhoea, weight loss, and changes in appetite. Watch for accompanying mucus or blood in stools, and any changes in energy or alertness.

Recurrent diarrhoea or persistently loose stools lasting more than a few days
Unexplained gradual weight loss — keep a record of changes
Reduced appetite or a noticeable change in eating habits
Lethargy and a significant drop in activity level
Stools containing mucus or blood — pay close attention to this sign
If any abnormalities appear, arrange a clinic visit promptly for assessment

Seek emergency care immediately if you notice the following symptoms:

⚠️ Persistent vomiting or obvious dehydration — seek immediate veterinary care
⚠️ Large amounts of fresh blood or black tarry stools — requires urgent attention
⚠️ Inability to eat or progressive weakness — needs emergency evaluation

02How to monitor at home? Key observations and criteria for seeking emergency care

Keeping systematic records at home helps the vet assess the condition and its progression. We recommend preparing a short-term log of bowel movements and diet.

Record the number of daily bowel movements and any changes in stool consistency and colour
Weigh your pet weekly and log changes for comparison
Observe your pet's alertness and how they interact with people or other animals
Note any changes in appetite, food intake, or food preferences
Watch for straining during bowel movements or signs of discomfort
Photograph or video abnormal stools and bring them to the consultation

03How will the vet make a diagnosis? Common diagnostic tests

After arrival, the vet will first conduct a physical examination and baseline blood tests to assess overall condition, then arrange stool tests, imaging, and endoscopic sampling as needed to confirm the cause.

Physical examination

assessing overall condition, abdominal tenderness, and degree of dehydration

Complete blood count and biochemistry

evaluating for anaemia, inflammation, and liver and kidney function

Faecal examination and parasite testing

to rule out infection or parasitic causes

Gastrointestinal endoscopy

visualising the mucosa and obtaining biopsy samples directly

Histopathology of biopsy specimens

confirming the pattern of intestinal inflammation and tissue changes

Advanced imaging (if needed)

CT scan or ultrasound to evaluate complications

04How to treat and care for your pet after diagnosis? Medications, dietary changes, and care guide

Treatment centres on long-term dietary management, combined with veterinary medications and regular monitoring. Follow-up visits and tests help assess treatment response and adjust the care plan.

Long-term use of a gluten-free or hypoallergenic specialised diet as the cornerstone of management
Use medications as directed by the vet and monitor for possible side effects
Regular check-ups to assess weight, stool condition, and changes in clinical symptoms
Follow-up blood tests, imaging, or pathology reports to confirm disease control
Key home care: maintain a consistent diet and continue logging bowel movements
If symptoms do not improve, consider referral to a specialist gastrointestinal veterinary centre

05What to prepare before the vet visit? Key information to help the vet quickly identify the cause

Record the onset date and specific details of how symptoms have progressed

Keep a complete log of daily diet and whether there have been any recent food changes

Prepare at least three days' worth of records on bowel movement frequency and stool consistency

Bring a list of current medications and supplements, including dosage and frequency

Bring a stool sample, photos, or video footage for the vet's reference

If needed, book in advance with a specialist who has endoscopy and pathology capabilities
