02How to assess the situation at home: observation checklist and when to go to emergency
Keeping detailed records at home helps your vet quickly understand how symptoms are progressing and what your pet may have been exposed to.
- Note the time symptoms started, how often they occur, and how long each episode lasts
- Record the number of vomiting episodes daily, including the colour and contents
- Film any coughing or abnormal breathing on your phone for the vet to review
- Track daily changes in food and water intake
- Monitor and record stool colour, frequency, and any signs of bloating
- If there is no improvement within a short period, seek a clinic with X-ray or imaging equipment

At the clinic, the vet will begin with a physical examination and then order blood tests, imaging, or further diagnostics as needed to assess the extent of organ involvement.
Full physical examination, including auscultation and palpation of the chest and abdomen
Complete blood count (CBC) and blood biochemistry to assess organ function
Chest and abdominal X-rays to evaluate the lungs and gastrointestinal tract
CT scan if findings are complex or unclear on standard imaging
Endoscopy or surgical assessment if foreign body obstruction or internal injury is suspected
04How is the condition treated and managed? Medications, diet adjustments, and home care
Treatment depends on the extent of exposure and any complications; ongoing monitoring and regular follow-up visits are essential after initial treatment.
