Overview
Grass seeds might look harmless, but they can pose a serious risk to dogs. Their sharp, barbed tips can pierce the skin or get into ears, eyes, or noses — and once inside, they don’t break down. Instead, they can move deeper into the body, causing pain, infection, or even damage to vital organs.
Long grass poses the greatest risk. Most cases happen in summer (the odds of a dog being diagnosed with grass seed-related issues in July are over 170 times higher than in January), and the most-affected breeds are those who are very active or long-coated. The best protection is prevention: check your dog after every walk, and speak to your vet straight away if you find a seed or notice signs of discomfort.
