During summer and early autumn, cereal crops stand dry in the fields, harvest season gets into full swing, and warm weather turns wayside grasses yellow and brittle. While we enjoy sunny afternoons outdoors, a quiet plant danger lurks for our four-legged companions: grass awns, commonly known as foxtails. Popular breeds like the Golden Retriever, Cocker Spaniel, and poodle mixes with long, dense coats are especially prone to catching these barbed seeds in the warmer months. Animal welfare organizations like TASSO e.V. and veterinarians issue urgent warnings every late summer about these bristly grass heads.
It is a familiar scene this time of year: a lively dog eagerly sniffs along the edge of a field between wild barley and wheat, brushing its ears against dry stalks—and suddenly stops playing, visibly restless. In this guide, you will learn why grass awns are so treacherous and how you can protect your dog effectively throughout summer and late autumn.
What Are Grass Awns and Foxtails, and Why Are They Dangerous?
Grass awns—often referred to generally as foxtails or grass seeds—are the stiff, bristle-like attachments found on seed heads of cereals such as barley and wheat, as well as many wild grasses. Biologically, they help anchor seeds into the soil or hitch a ride on the fur of passing animals to spread.
The problem lies in their structural design: they feature microscopic, backward-pointing barbs. Once tangled in fur, every movement your dog makes—walking, muscle twitches, or head shaking—drives the awn forward like a tiny arrow. It cannot back out on its own. Instead, it relentlessly works its way forward through the skin, ear canals, nostrils, or deep between toes.
Common Entry Points and Warning Signs in Dogs
After every walk in warm weather, inspect these key areas of your dog's body closely:
1. Paws and Between the Toes
Grass awns easily snag in the fine hair between paw pads. Once they pierce the delicate skin, painful inflammation, tract infections, or abscesses develop rapidly.
- Symptoms: Sudden limping, excessive licking or chewing at a paw, redness, and swelling between toes.
2. Ear Canals and Ears
Floppy-eared breeds in particular gather grass seeds with their ears while sniffing low to the ground. If an awn slips down the ear canal, it can migrate all the way to the eardrum.
- Symptoms: Sudden, violent head shaking, tilting the head to one side, pawing at the ear, or whining.
3. Nose and Airway
Sniffing vigorously through dry grass stalks can cause fine awns to be inhaled directly into the nasal passages.
- Symptoms: Sudden, fits of sneezing, rubbing the muzzle with paws, or unilateral nasal discharge.
4. Eyes
If an awn gets trapped under the eyelid or behind the third eyelid, it quickly inflicts painful corneal scratches or ulcers.
- Symptoms: Squinting, heavy tearing, redness, and pawing at the face.
First Aid: What to Do If You Suspect an Awn
If you spot an awn resting loosely on your dog's coat or sitting superficially on the skin after a walk, gently pluck it out with your fingers or a pair of tweezers. Check the area afterward for any signs of redness or puncture marks.
Important note: If the grass awn is already embedded deep within the skin, ear canal, nose, or eye, never attempt to pull it out with force. You risk breaking off the tip, leaving the barbed fragment lodged deep within the tissue. Visit a veterinary clinic right away. Pain relief or mild sedation is frequently necessary to remove the foreign body completely and safely.
Practical Prevention Tips for High Summer
A few routine precautions will significantly reduce your dog's risk during the summer months:
- Avoid field edges: Stick to shady woodland trails or mowed park paths during peak season, and avoid letting your dog dash through unharvested grain fields or overgrown meadows.
- Check paws after every walk: Get into the habit of palpating paw pads, interdigital spaces, armpits, groin, and ears as soon as you return home.
- Keep coats trimmed: On long-haired dogs, neatly trim the feathering between paw pads and around ear openings during summer. Veterinarians regularly recommend keeping coat length tidy in these vulnerable spots so seeds have nothing to cling to.
Frequently Asked Questions (FAQ)
Can a grass awn work its way out on its own?
No. Because of the microscopic barbs, muscle contractions and skin movement almost always propel awns deeper into tissue. Natural expulsion without veterinary care is exceptionally rare and carries severe risks of deep infection and abscess formation.
Which dog breeds are most at risk?
Dogs with long, thick, or curly coats, as well as drop-eared breeds, face the highest risk because plant parts cling readily to their fur. Short-coated breeds remain susceptible too, particularly around their paws and muzzles.
How much does it cost to have an awn removed by a vet?
Costs depend on where the awn is located and how deeply it has penetrated. A superficial removal is straightforward and inexpensive. If the foreign object sits deep within an ear canal or requires surgical extraction under sedation or anesthesia, treatment costs will be higher.
Conclusion: Staying Safe Through Late Summer
Grass awns and foxtails represent a genuine hazard in late summer and early autumn. With vigilant post-walk checks and proactive grooming, you can enjoy the warm season safely. Watch your dog's subtle cues and act promptly at the first sign of sudden limping, head shaking, or persistent sneezing.
