Foxtails are the reason a lot of dogs end up at the vet every summer, and I had never heard of them until Sami was almost four. They're a common grass-like weed with barbed seeds that hook onto a dog's coat, burrow into skin, and only ever travel in one direction: deeper. For a low-to-the-ground, fluffy-coated breed like a Westie, they're a real seasonal hazard.

Here's what foxtails do, the warning signs, and the three habits I use to keep Sami safe. Owner experience, not veterinary advice - if you suspect a foxtail has gone somewhere it shouldn't, that's a vet call, not a wait-and-see.

What a Foxtail Is

Foxtail is a grass-like weed that appears in spring and dries out in early summer - the bushy seed head looks like a fox's tail, hence the name. Each seed has a sharp point and backward-facing barbs. The barbs are the problem: once a seed attaches to fur or pierces skin, every movement works it further in, never out.

They grow everywhere - roadsides, parks, empty lots, the edges of walking trails. If you've walked past dry, bristly golden grass in June, you've walked past foxtails.

Why They're Dangerous

A foxtail seed can work its way between toes, up a nose, inside an ear, and even under an eyelid. After piercing the skin it can keep migrating under the surface, causing infections and abscesses along the way. In rare, extreme cases seeds have traveled to the lungs or other organs - rare enough not to panic about, real enough to take seriously.

The common scenarios are less dramatic but plenty bad: a seed embedded between the toes that abscesses, one deep in the ear canal, or one lodged in the gums.

What Other Westie Owners Went Through

When I posted about foxtails on our Instagram, the messages that came back convinced me this deserved more than a passing mention. Several Westies needed surgery to remove a seed from a paw - one went in the top of the paw and came out the bottom, with an emergency bill of 750 dollars. Multiple dogs needed full anesthesia to get seeds out of their ears. One owner's friend lost her dog after a seed traveled up the nose. Several described paw infections that took weeks to clear.

The pattern in those stories: paws and ears are the usual entry points, longer coats pick seeds up more easily, and the deeper a seed gets, the more invasive the fix.

When and Where to Worry

Foxtail season runs from late spring through summer - the plants grow green and harmless in spring, then dry out, and the dry seed heads are the dangerous phase. The risk peaks in early summer when the seeds detach at a touch.

They're worst in dry-summer climates - the western US is notorious, and our Mediterranean corner of Portugal has plenty - but some variety of barbed grass seed exists almost everywhere. You may hear vets call them grass awns; same problem, same treatment. The practical rule doesn't need botany: dry, golden, bristly grass at the edge of the path in summer is a no-go zone.

Signs Your Westie Picked One Up

Paws: persistent licking of one spot, swelling or redness between the toes, or a small weeping hole. If your Westie won't leave one toe alone, look closely.

Nose: sudden violent sneezing fits, pawing at the nose, sometimes a nose bleed. This one is urgent - seeds move fast in the nasal passages.

Ears: head shaking, head tilt, scratching at one ear, holding the ear oddly. An embedded seed feels a lot like an ear infection from the outside, and only the vet's otoscope can tell the difference.

Eyes: pawing at one eye, swelling, redness, tearing, or discharge. Also a same-day vet situation.

Three Habits That Keep Sami Safe

1. Route awareness. I simply don't let Sami wander through dry tall grass in foxtail season. On trails, he stays on the path; fields of golden bristly grass are a hard no. It's the least fun rule and the most effective one.

2. A short summer coat, especially the feet. Foxtails attach to fur before they reach skin, so less fur means fewer hitchhikers and easier spotting. We keep Sami's coat short in summer anyway for heat reasons - the feet and the hair between the toes get particular attention. The full seasonal routine is in our summer grooming guide.

3. The after-walk check. A quick pass with a fine comb after every walk, plus a look between all the toes, in both ears, and around the face. It takes two minutes and it's already caught things: I found two foxtail seeds riding in Sami's coat a few days after I learned all this - and a third one in our bed the next morning. Nothing had pierced skin. Lesson received.

Can You Remove One Yourself?

Depends entirely on where it is. Riding loose in the coat: yes, just pick it off or comb it out - that's the whole point of the after-walk check. Sitting visibly between the toes but not embedded: you can pull it out gently with tweezers, then watch the spot for a few days for swelling or licking.

Anything already under the skin, or anywhere near an ear canal, nose, or eye: no. The barbs mean pulling on a partially embedded seed can snap it, leaving the tip inside to keep traveling - which turns a simple removal into imaging and surgery. And a seed deep in an ear or nose is painful enough that most dogs need sedation for the vet to even look properly, let alone for an amateur with tweezers. Know the limit: coat and surface, you; anything deeper, the vet.

When to Call the Vet

Found on the coat, not attached: just remove it, no drama. Anything beyond that, be conservative. Call the vet the same day if you see an embedded seed, a swollen or weeping spot between the toes, sudden sneezing fits, one-sided ear trouble, or anything involving an eye. A foxtail that's just gone in is a quick removal; a foxtail that's had a week to travel can mean sedation, imaging, and surgery. Early is cheap, late is not.

What the Vet Visit Looks Like

If you do end up at the clinic, the shape of the visit depends on how far the seed has gone. A visible seed between the toes is often a thirty-second removal with forceps. A seed in the ear canal usually means an otoscope exam and, for most dogs, sedation - the canal is too sensitive for a wide-awake extraction, which several of the owners who wrote to us confirmed from experience. A seed that's been migrating for a while may need ultrasound or surgical exploration to find. The pattern is the same everywhere: hours cost little, weeks cost a lot.

The Takeaway

I went almost four years as a dog owner without knowing this weed existed, and apparently half our Instagram followers had a foxtail horror story waiting. Now it's just part of the summer routine: watch the route, keep the coat short, check after walks.
