When to See a Vet

Seek emergency care immediately

  • Sudden paralysis of the hind limbs or whole body, unable to walk
  • Persistent severe seizures that do not stop on their own
  • Purple lips or gums with signs of difficulty breathing

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

  • Significantly reduced appetite lasting more than one day
  • Intermittent muscle twitching or trembling
  • Staggering or frequent falling while still able to move

01What Symptoms Indicate Something Is Wrong?

Bromadiolone (a common anticoagulant or non-anticoagulant rodenticide) poisoning in dogs and cats primarily presents as neurological and behavioural changes. Early signs can be subtle — watch closely for changes in appetite and activity level.

  • Noticeably reduced appetite or complete refusal to eat
  • Seizures or intermittent muscle spasms
  • Wobbly gait, ataxia, or frequent stumbling and falling
  • Frequent tremors or brief episodes of muscle twitching
  • Limb weakness or partial paralysis
  • Lethargy, dulled responsiveness, or increased drowsiness

Seek emergency care immediately if you notice the following symptoms:

  • ⚠️ Sudden collapse of the hindlimbs or whole body, unable to walk
  • ⚠️ Continuous severe seizures that do not stop on their own
  • ⚠️ Blue or purple discolouration of the lips or gums with difficulty breathing

02How to Assess Symptoms at Home: Key Observations and When to Seek Emergency Care

Systematic record-keeping and video footage at home can help your vet make a faster assessment — focus on changes in appetite, alertness, and bathroom habits.

  • Log changes in appetite and note the time of each meal
  • Record short videos of any tremors or seizures on your phone
  • Monitor activity level and alertness throughout the day and night
  • Record the frequency, colour, and any blood in urine or faeces
  • Preserve any suspected bait or vomit, and take clear photographs
  • If symptoms worsen, arrange a specialist consultation as soon as possible

03How Will the Vet Diagnose This? Common Diagnostic Tests

Upon arrival, the vet will begin with a physical examination and follow up with blood, coagulation, and imaging tests to assess the degree of toxicity and any complications.

Physical examination

assessment of cardiopulmonary function, neurological reflexes, and body temperature

Complete blood count and biochemistry panel to assess organ function

Coagulation profile to evaluate the risk of haemorrhage or clotting disorders

Cytology or additional tests to rule out infection or other underlying causes

CT or MRI to evaluate central nervous system complications or brain lesions

Seek a clinic equipped with coagulation testing and advanced imaging capabilities

04Post-Diagnosis Care: Medications, Dietary Adjustments, and Home Care Guide

After treatment, the focus is on medication adherence, follow-up testing, home care, and preventing re-exposure. Schedule regular check-ups to monitor recovery.

  • Attend all follow-up appointments and schedule blood tests as directed by your vet
  • Administer medications as prescribed and monitor for any adverse reactions
  • Manage your pet's diet and keep them away from any suspected bait or toxins
  • Ensure your pet stays warm at home and avoid strenuous activity or jumping
  • Arrange periodic specialist follow-up and functional assessments at a referral hospital
  • Return to the vet immediately or see a specialist if new symptoms appear or existing ones worsen
