Before offering cucumber
- Check the exact animal and preparation: the listed suitability is Dogs; Rabbits; Guinea pigs; Hamsters. A food being edible does not make it a complete diet.
- Follow the preparation advice: Wash, slice into species-appropriate pieces. Peel is safe for dogs; offer smaller amounts to small pets. Do not substitute a seasoned or processed version and assume the same safety.
- Portion guidance: A few slices for a medium dog; a thumbnail piece for small pets, a few times a week. 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.
