Grass Seeds & Ear Infections: The Hidden Dangers of Summer Meadows

Grass seeds are a common summer hazard for dogs, often getting lodged in ears or between paws. Watch for head shaking, limping, excessive licking or swelling and check your dog over after every walk in long grass. Caught early, they're usually a quick, straightforward fix at the vet.

Nothing says summer quite like watching your dog bound through a meadow, ears flapping and nose buried in the long grass. It's the stuff of dream walks. But hidden in all that lush greenery is a small, spiky troublemaker that catches out even the most attentive owners every year: the grass seed.

These tiny, arrow-shaped seeds are barely the size of a grain of rice, but don't let that fool you. Their pointed tips and one-way barbs mean they're brilliant at burrowing in and hopeless at coming back out on their own. Once caught in your dog's fur, they can work their way into ears, paws, eyes and even under the skin, causing real pain and, if left too long, some very costly vet visits.

The good news? A quick check after every walk is usually all it takes to catch a grass seed before it becomes a problem. Here's what to look out for.

Grass seeds are shaped a bit like tiny darts or fish hooks, pointed at one end, barbed at the other. That barbed end means they can travel in one direction only: forwards, into your dog. They can't be brushed back out the way they went in, which is exactly why they're so good at working themselves into ears, between toes, and under eyelids.

Long grass sheds seeds most heavily from late spring through the summer months, so any walk through meadows, verges or overgrown paths is a chance for your dog to pick one up.

Ears are one of the most common places for a grass seed to cause trouble. The seed works its way down the fur around the ear and into the canal, where it can sit right up against the eardrum.

Signs to look out for include:

If your dog is shaking their head and won't stop, don't wait to see if it settles down. A vet will usually be able to spot and remove the seed with an otoscope, but the longer it sits there, the greater the risk of a painful ear infection setting in.

Paws are the other classic hotspot, especially between the toes where fur tends to be longer and softer.

Look for:

Because grass seeds don't show up on x-rays, they can be surprisingly tricky for a vet to locate once they're under the skin, which is exactly why catching one early, while it's still visible, makes life so much easier for everyone involved.

If you catch a seed sitting in the fur before it's pierced the skin, you can usually remove it yourself with clean fingers or tweezers. Once it's gone in, though, resist the urge to dig around, it's a job best left to your vet, who has the right tools to remove it safely without pushing it in further.

If in doubt, a same-day check-up is always worth it. As the RSPCA and most UK vets advise, grass seed injuries are usually straightforward to treat when caught early, but can lead to abscesses or deeper infections the longer they're left.

The best defence against grass seeds is a simple once-over after every walk, particularly if you've been anywhere near long grass, meadows or overgrown paths. Make it part of your routine:

Dogs with longer or feathery coats – think spaniels, retrievers and terriers – are especially prone, so a summer trim around the ears and paws can make checks even easier.

At K9 Leisure Club, our team knows exactly what to look for after a day of play in the fields, and every dog gets a proper once-over as part of their visit with us. If your dog's had a paw or ear niggle that just won't settle, our hydrotherapy sessions can also help soothe any lingering stiffness or discomfort once your vet has given the all-clear.

Book your dog in with us and let them enjoy all the fun of summer, with a little extra peace of mind for you.
