What happens if a pet eats shining pondweed?
Because shining pondweed is non-toxic, a curious nibble will not poison a cat or dog. That said, no plant is meant to be eaten: a large quantity of any foliage can still cause mild, short-lived stomach upset or vomiting simply through fibre and volume. Persistent vomiting, diarrhoea, or lethargy after eating any plant is always worth a call to your vet, because the reaction may be to soil, fertiliser, or a pesticide rather than the plant itself.
What to do if your pet ate shining pondweed
- Remove any plant material from your pet's mouth and move shining pondweed out of reach.
- Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
- Do not induce vomiting unless a vet or poison-control specialist instructs you to.
- Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
- Bring a leaf or photo of shining pondweed to the appointment so it can be treated correctly.
