Occasional nibbles are usually tolerated, but problems occur with large amounts, certain plant stages or vulnerable animals.

- Usually none in alpacas
- Rash in people handling fleece or animals that brushed through it
If your alpaca ate a lot of poison ivy
- Remove access and estimate how much was eaten.
- Watch for the signs listed above over the next 24–72 hours.
- Call your vet if any signs appear or if a pregnant, young or sick animal ate a large amount.
- Reduce the plant in your pasture and keep good forage available so alpacas aren't driven to eat it.

Keeping pastures safe
- Walk every paddock and fence line each season and remove toxic plants, including roots.
- Never throw garden, hedge or lawn clippings over the fence.
- Check pastures after storms for fallen branches (cherry, red maple).
- Buy hay from known sources and inspect it for weeds.
- Keep pastures well managed — hungry alpacas eat plants they would normally avoid.
