Is Familial Shar-Pei Fever contagious to other pets?

Familial Shar-Pei Fever is primarily linked to breed genetics and immune dysregulation rather than infectious agents, so it is not a typical contagious disease. If you are concerned, consult your vet, who may recommend isolating or examining your other pets as a precaution.

How do I care for my dog at home during an episode?

Monitor and record your dog's alertness, appetite, vomiting, and bowel movements. Ensure fresh water is always available and avoid force-feeding. If symptoms persist or worsen, seek veterinary care promptly.

What tests are needed to find the cause?

A physical examination along with blood and biochemistry tests is usually recommended. Imaging or tissue biopsy may be added if necessary, with further management planned based on the results.

How long can symptoms last before I should be concerned?

If symptoms last more than 24–48 hours, or if signs such as dehydration or blood in the stool appear, seek veterinary attention promptly and follow your vet's advice for monitoring and follow-up.

How much do the tests and treatment usually cost?

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

02How to assess your pet at home: what to observe and when to seek emergency care

Specific items to observe and document at home, helping your vet get a complete picture during the consultation.

Note the onset time and duration of any changes in alertness or activity level
Estimate and record daily food intake, willingness to eat, and feeding behaviour
Record the number of vomiting episodes, timing, and the colour and contents of vomit
Note and photograph changes in stool colour, texture, and frequency
Weigh your pet at the same time each day and log changes to track weight loss
If symptoms persist or worsen, arrange a vet appointment promptly and bring your observation notes

03How will the vet diagnose the problem? Common diagnostic tests

Common tests and imaging performed at the clinic to identify possible causes and assess severity.

Physical examination

assessment of temperature, pulse, mucous membranes, and overall condition

Blood work

complete blood count (CBC) to evaluate for infection or immune response

Biochemistry panel

assessment of liver and kidney function and electrolyte balance

X-ray

evaluation of structural changes in the chest, abdomen, or urinary system

Advanced imaging (CT or ultrasound)

assessment of deeper or more complex lesions

Tissue biopsy

performed when needed to confirm a pathological diagnosis

04Treatment and home care after diagnosis: medication, diet, and management guide

An overview of common treatment approaches and key follow-up points, emphasising tailored therapy based on test results and regular monitoring.

Symptomatic and supportive care tailored to diagnostic findings
Antibiotics or targeted medications may be required if infection or complications are present
Immune-modulating drugs such as corticosteroids require careful risk-benefit assessment and regular monitoring
Severe cases may require hospitalisation for supportive care such as fluid therapy or oxygen supplementation
Schedule regular follow-up visits with blood and biochemistry tests to monitor treatment response
If advanced treatment or specialist evaluation is needed, your vet will recommend a referral

05What to prepare before your vet visit: key information to help your vet work quickly

Bring a written log of when symptoms started and how they have changed over time

List the past week's diet, treats, and all current medications or supplements

Prepare photos of vomit or stool and short video clips of any key episodes
