MAKE YOUR OBSERVATIONS USEFUL
Bring a clear timeline to your vet
For the changes covered in this guide, note when they started, how often they happen, whether they are worsening and how they differ from your pet’s usual routine. List recent diet changes, medicines, travel or possible ingestion in time order. Add photos or a short video only when it is safe and will not delay care.
