Foxtails in Dogs: Spotting Grass Awns Before They Cause Harm

If your dog has been sneezing violently after running through tall grass, or suddenly licking obsessively at one paw, you're right to be concerned. Every summer at Hearthstone Animal Clinic in Cypress, TX, I pull dozens of grass awns out of ears, paws, noses, and sometimes stranger places. These tiny plant structures cause pain out of proportion to their size, and the longer they stay embedded, the worse things get.

Most owners have never heard the term "foxtail" until their dog has one. That's the part I want to change. Understanding what these things are and how they behave can save your dog a lot of suffering, and save you an emergency visit.

What exactly is a foxtail or grass awn?

A grass awn is the seed-dispersal structure of certain grasses, shaped like a tiny spear or barbed arrow. The most notorious are foxtails (from grasses in the genus Hordeum and Setaria), but many wild grasses produce similar structures. They're designed by evolution to do one thing: burrow forward. The barbs point backward, so once the awn enters tissue, it can only move deeper.

In Texas, these grasses dry out and become most dangerous from late spring through early fall. You'll find them in unmowed fields, along fence lines, in vacant lots, and at the edges of trails. But they also show up in backyard lawns that border wild areas.

Where do foxtails embed in dogs?

Foxtails enter through any opening or soft tissue. The most common locations I see in practice:

Paws (between the toes)

This is the number one spot. The awn works its way between the toes, punctures the skin, and starts migrating. You'll see sudden licking, limping, or a small swelling that looks like an abscess. Sometimes a draining tract forms, a small hole that oozes and never quite heals.

Ears

Dogs with floppy ears or lots of ear hair (Cocker Spaniels, Golden Retrievers) are especially prone. The awn falls into the ear canal and works its way toward the eardrum. Signs include violent head shaking, pawing at the ear, and pain when you touch the base of the ear. This is an emergency because the awn can perforate the eardrum.

Nose

Sniffing in tall grass is all it takes. The classic presentation: sudden, explosive sneezing (sometimes with blood), then a discharge from one nostril that doesn't resolve. Dogs will sneeze dozens of times in a row, then seem better, then sneeze again. If this happens after outdoor time, suspect a nasal foxtail.

Eyes

The awn lodges under the eyelid or third eyelid. You'll see squinting, tearing, redness, and pawing at the face. This one can cause corneal ulcers if not addressed within hours.

Skin and deeper tissues

Occasionally, awns penetrate the skin elsewhere (chest, flank, groin) and migrate internally. I've seen them travel through muscle tissue and end up near the spine or in the chest cavity. These cases often start as a "mystery abscess" that drains, heals over, then reappears somewhere else.

How do I know if my dog has a foxtail?

The signs depend on the location, but here's the pattern to watch for:

• Sudden onset after outdoor activity (this is key: normal infections don't appear out of nowhere)
• Focused attention on one body part (one paw, one ear, one nostril)
• Progressive worsening despite home care
• Swelling or draining tract that doesn't respond to routine wound treatment

If your dog was fine this morning, spent an hour in the backyard, and is now frantically licking one paw, that's a foxtail until proven otherwise.

Can I remove a foxtail at home?

Sometimes, but usually no. Here's the honest breakdown:

If you can see the entire awn (sticking out of the fur, not yet embedded), you can carefully pull it out with tweezers. Check the area for more. These grasses tend to cluster.

If the awn has punctured the skin or entered an opening, don't dig for it. The barbs make extraction difficult, and pushing it deeper is easy to do. Ears and eyes especially need professional evaluation. For nasal foxtails, there's no safe home removal; the dog needs sedation and scoping.

The instinct to handle it yourself makes sense: it's just a piece of grass. But these things migrate fast. An awn that entered the paw Monday can be three inches deep by Thursday. Early removal (when the awn is still near the surface) is far simpler than chasing it through tissue later.

How does a veterinarian remove a foxtail?

It depends on where the awn is.

Paw or skin

If there's a visible entry point or draining tract, I'll often sedate the dog, explore the wound, and retrieve the awn with forceps. Success rates are high if we catch it early. Chronic cases sometimes need ultrasound or surgical exploration.

Ear canal

I use an otoscope (and usually sedation) to visualize the awn and extract it with alligator forceps. The sooner we do this, the better. Awns that reach the eardrum can cause serious damage. According to the American Veterinary Medical Association, prompt removal of ear foreign bodies is essential to prevent perforation and infection.

Nose

Nasal awns require anesthesia and rhinoscopy (a small camera passed into the nasal cavity). Most general practices, including ours, can handle straightforward cases. Deeply migrated awns sometimes need referral to a specialist.

Eye

With topical anesthesia, I can usually retrieve an awn from under the eyelid in the exam room. Corneal damage needs treatment, so we'll assess for ulcers at the same time.

Cost varies by location and complexity. A straightforward paw awn extraction with sedation might run $250 to $400. Nasal or ear cases requiring scoping are higher. If you're concerned about pricing, we're always transparent about estimates before we proceed.

How can I protect my dog from foxtails?

Prevention isn't always possible, but you can reduce the risk:

• Keep your lawn mowed short and remove wild grasses before they go to seed.
• Avoid fields and trails with tall, dry grass during peak season (May through September in Texas).
• Check your dog after every outdoor session: run your fingers through the coat, look between the toes, inspect inside the ears. This takes 60 seconds and catches awns before they embed.
• Keep long-haired dogs trimmed around the paws and ears during summer. Less fur means fewer hitchhikers.
• Consider protective boots for dogs who work or hike in high-risk areas (hunting dogs, ranch dogs).

If you're dealing with other summer issues like allergies or skin problems, those can overlap with foxtail irritation. Our guide to dog allergies in Cypress covers what else might be causing your dog to scratch and lick.

When does a foxtail need emergency care?

Some situations shouldn't wait for a scheduled appointment:

• Eye involvement: squinting, tearing, rubbing at the face after outdoor time. Corneal damage can happen fast.
• Ear pain with head tilt or shaking: the awn may be approaching the eardrum.
• Bloody nasal discharge: one-sided bleeding or discharge suggests a nasal foreign body.
• Swelling that's hot, painful, or rapidly growing: migration can cause serious infection.

If you're seeing any of these signs, you can get your pet seen the same day at our clinic.

The bottom line on foxtails in Cypress

Foxtails are one of those hazards that seems minor until it isn't. A dog who picked up an awn on a Saturday afternoon walk can have a serious infection by the following week. The good news: most cases resolve quickly when caught early. The key is knowing what to look for and acting before the awn burrows deeper.

If your dog is suddenly licking one paw, shaking their head, sneezing after being outside, or showing signs of a wound that won't heal, don't wait to see if it gets better. Schedule a visit at Hearthstone Animal Clinic or give us a call at (281) 859-9244. We're in Cypress, TX, and we see these cases all summer. Catching a foxtail early is always easier (and cheaper) than chasing one that's had time to migrate.
