Before offering courgette (zucchini)
- Check the exact animal and preparation: the listed suitability is Dogs; Rabbits; Guinea pigs; Bearded dragons; Plecos and other grazing fish. A food being edible does not make it a complete diet.
- Follow the preparation advice: Raw in small pieces for dogs and small pets; blanched slices weighted down for fish; raw for reptiles. Do not substitute a seasoned or processed version and assume the same safety.
- Portion guidance: A few chunks for dogs; a slice for fish tanks, removed after 24 hours. For a pet on a prescribed diet, discuss extras with the vet first.
- If your pet develops vomiting, diarrhoea or discomfort, stop offering the extra and seek advice. Suspected poisoning or breathing difficulty needs immediate veterinary help.
