  • Unilateral or intermittent limping with reduced activity
  • Visible flinching or crying out when the affected limb is touched
  • Recurring fever, or noticeably reduced appetite with weight loss

01What symptoms indicate a problem?

Panosteitis commonly presents with systemic signs alongside localised bone pain, which can affect activity levels and appetite.

  • Lethargy and noticeably reduced activity
  • Decreased appetite or gradual weight loss
  • Recurrent fever or unstable body temperature
  • Lameness and obvious tenderness in one or more limbs
  • Visible signs of pain or depressed demeanour

Seek emergency care immediately if you notice the following symptoms:

  • ⚠️ Persistent high fever with extreme lethargy and complete loss of appetite
  • ⚠️ Sudden inability to stand or complete weakness in all limbs
  • ⚠️ Wound discharge or visible pus draining from a site

02How to assess the problem at home? Key observations and when to seek emergency care

Careful at-home observation and record-keeping before the visit helps the vet quickly assess the condition and prioritise treatment.

  • Record when symptoms first appeared and how they have changed over time
  • Weigh your pet daily and note any changes in weight and appetite
  • Measure and record your pet's temperature at home
  • Film your pet walking or limping on your phone to share during the consultation
  • Observe for any abnormalities in drinking, urination or defecation, and activity levels
  • If symptoms persist or worsen, arrange a vet visit promptly

03How will the vet diagnose this? Common diagnostic tests

The vet will combine physical examination, imaging, and blood tests to assess the extent of the lesion and identify the likely cause.

Physical examination

palpation to identify painful areas and swelling

X-ray

to detect periosteal proliferation or changes in bone density

Tissue biopsy or sample collection

to assess infection or other lesions

Advanced imaging (CT/MRI)

to localise lesions and evaluate their extent

Blood and biochemistry panel

to screen for infection markers and organ function

Referral to a specialist hospital with advanced imaging equipment if required

04How to treat and care for your pet after diagnosis? Medication, dietary adjustments, and care guide

Treatment may include hospitalisation for supportive care, anti-infective therapy, or surgical intervention, with regular follow-up imaging and blood work.

  • IV fluids or hospitalisation for supportive care to stabilise the condition if needed
  • Medical treatment and medication monitoring arranged according to the vet's assessment
  • Dietary management with regular monitoring of body weight and appetite
  • Daily observation of any wounds or injection sites for redness, swelling, or discharge
  • Follow-up imaging or blood work scheduled as directed by the vet
  • Referral to an infectious disease or orthopaedic specialist for ongoing follow-up is recommended

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