Foxtail plants can be risky for your dog...

The foxtail plant is a grass-like weed. The barbed seed heads of the foxtail plant can work their way into any part of your dog or cat, from the nose to between the toes and inside the ears, eyes and mouth. They can even simply dig themselves directly into a patch of skin.

The danger of foxtails goes beyond simple irritation. Because these tough seeds don't break down inside the body, an embedded foxtail can lead to serious infection for your dog. It can even lead to death if left untreated. The seeds can be hard to find in your dog's fur.
