Veterinary notes and prevention
Compost heaps and allotments are the usual source. Small nibbles usually cause mild upset; large amounts can affect the kidneys.
Prepare the information your vet needs
- For Rhubarb leaves, report the exposure route: Eating the leaves, which contain soluble oxalates; the stalks are far less toxic. Tell the clinic the time, possible amount and your pet's species and approximate weight.
- Photograph the packaging, ingredient list or plant if safe. Do not handle contaminated material without protection or delay the call to identify it perfectly.
- Keep other animals away from the source. An animal may appear normal before signs develop; do not wait for symptoms or calculate a home 'safe dose'.
- Follow the clinic's transport instructions. Do not give food, medicines or home remedies unless instructed, and take packaging with you if available.
