Every day in the summer we remove foxtails, a weed rampant in California with seeds that look like a fox's tail. The tip of each seed has barbs, allowing it to move only deeper into your pet's eyes, ears, nose, feet, genitals, and coat. Foxtails cause a lot of discomfort to dogs and cats and can even migrate internally, potentially causing organ damage and severe illness.
Check your dog's feet and coat for foxtails after a hike. If you think your dog or cat has a foxtail that you cannot remove at home, take them to your veterinarian as soon as possible to reduce the risk of the foxtail migrating deeper.
