- Check paws, nose, ears, armpits and groin after walks.
Don't
- Don't try to pull out a seed that is partly buried; it can be pushed deeper.
Signs to watch for
- Licking one spot or swelling between the toes
- Limping
- Red or draining sore that won't heal

- Pawing at a runny eye
Why
Foxtails and other grass awns have barbs that let them move only forward, so once embedded they work their way in. Inhaled seeds can reach the lungs or brain.
