Grass seeds are one of the most common reasons dogs end up at the vet in July. Their sharp, arrow-shaped tips catch in fur during walks, then pierce the skin and burrow inwards, most often in the paws and ears. The two best defences are simple: check your dog thoroughly after every walk, and keep the fur around their paws and ears trimmed through summer.
Many dog lovers I speak to have never heard of this until one expensive vet visit later. UK vets report that a dog is over 170 times more likely to be treated for a grass seed problem in July than in January. Here is what to look for and how to keep your dog safe.
Why are grass seeds so dangerous for dogs?
The troublemakers are the dart-shaped seed heads of wild grasses like foxtails and barley grass, which dry out in early summer and detach at the lightest touch. Each seed has a pointed tip and backward-facing barbs, so once it hooks into fur it only travels one way: inwards. A seed can pierce the skin, slip between the toes, or drop into an ear canal, and because it does not show up on X-rays it can be hard to find once it has burrowed. Left untreated, a migrating seed can cause infections and abscesses, and in rare cases organ damage. That is why vets take a limping paw or a shaking head so seriously in July and August.
How do I know if my dog has a grass seed?
The signs depend on where the seed has lodged, and usually appear within hours or days of a walk:
- Paw: constant licking or nibbling at one foot, a red swelling between the toes (sometimes with a small oozing hole), or limping.
- Ear: sudden violent head shaking, scratching at one ear, a tilted head, or yelping when the ear is touched.
- Eye: a painful, weepy, half-closed eye that appears suddenly after a walk.
- Nose: fits of sneezing, pawing at the nose, or discharge from one nostril.
- Skin: a hot, sore lump anywhere on the body, especially in armpits and groin.
If you spot any of these in summer, ring your vet the same day. Grass seed problems get harder and more costly to fix the longer the seed travels.
Which dogs are most at risk?
Any dog that walks through long grass can pick up a seed, but breeds with feathered coats and hairy ears top the list: spaniels, cockapoos, setters, retrievers and other long-coated breeds. Hairy paws with tufts between the toes act like velcro for seeds.
I notice this in an odd way through my work. I spend my days hand-painting ceramic memorial pieces to match customers' photos of their dogs, and the soft feathered ears and fluffy paws I love painting most, on spaniels especially, are exactly the fur that grass seeds love too. If your dog has that lovely long coat, summer grooming is protective, not just cosmetic. You can see what I mean by feathering in my gallery.
How do vets remove grass seeds from dogs?
If the seed is visible, your vet may lift it out with special forceps in minutes. More often the area is painful or the seed has gone deeper, so dogs need sedation while the vet searches, flushes the wound and prescribes antibiotics. Costs in the UK typically start around 150 pounds for a simple removal and can run to much more if a seed has migrated. Never dig into a swelling yourself; you are likely to push the seed deeper.
How can I protect my dog from grass seeds?
- Stick to shorter grass in July and August, and mow your own lawn before it seeds.
- Trim the fur around paws, toes and ears through summer, or ask your groomer for a "summer tidy".
- Check your dog after every walk: run your fingers between each toe, look inside the ears, and comb through armpits, groin and tail.
- Brush long-coated dogs daily in seed season; a slicker brush lifts seeds out before they reach the skin.
- On the worst dry, seedy days, swap the meadow walk for games at home. I shared easy ideas in my post on mental stimulation for dogs.
Frequently asked questions
Can a grass seed come out of a dog by itself?
Rarely. The barbs mean seeds keep moving inwards, not outwards. If a seed is sitting loosely in fur you can remove it, but anything embedded in skin needs a vet.
What happens if a grass seed is left untreated?
It can burrow deeper, causing abscesses and infection, and in serious cases it can reach the chest or spine. Early treatment is simpler and cheaper.
What time of year are grass seeds a problem?
Late May to September in the UK and Europe, peaking in July when wild grasses dry out and shed.
Do cats get grass seeds too?
They can, though far less often, since cats groom constantly and avoid long dry grass. Long-coated outdoor cats are worth checking in summer all the same.
I hope this saves at least one of you a stressful vet trip this summer. My little studio exists because of how deeply people love their dogs, and that love is exactly why a five-minute check after each walk is so worth it.
