A grass seed (in Dutch: grasaar) is the sharp, arrow-shaped seed head of certain grasses that can lodge in a dog’s coat and work its way under the skin. Protective dog clothing made from smooth, tightly woven fabric is a good remedy, because it stops the seeds from reaching the coat in the first place.
If you have recently moved to the Netherlands with your dog, there is a seasonal hazard you may not know about yet: grass seeds. In Dutch they are called grasaren, and from late spring through the end of summer they are a familiar worry for local dog owners. The Dutch landscape is full of meadows, canal-side verges, parks and dune paths, and exactly those places are where grass seeds turn up. Many international dog owners only hear about the problem after their first vet visit. This blog explains what grass seeds are, why they matter here, and how the right clothing helps keep your dog safe during a Dutch summer.
Why grass seeds are such a common problem in the Netherlands
The Netherlands is a green, low-lying country, and its walking routes run through tall grass far more often than in many cities abroad. Verges along bike paths, unmown park edges, polders and coastal dunes are everywhere, and they are exactly the kind of terrain where dried grass seeds collect in summer. For a dog that loves to sniff and run through long grass, that means plenty of contact. If your previous home had mostly paved walks or short-cut lawns, this is likely a new risk for both you and your dog.
What exactly is a grass seed, and why is it dangerous?
A grass seed is the seed head of certain grasses. As summer dries them out, they break off into small, pointed darts covered in tiny barbs. Those barbs only allow the seed to travel in one direction: forward, into the coat and toward the skin. Common entry points are between the toes, inside the ears, around the eyes and in the armpits.
The real danger is that a grass seed can pierce the skin and migrate inside the body. Once it is under the surface it is no longer visible, so it often goes unnoticed while it keeps moving and causes inflammation or abscesses. In many cases a vet has to remove it surgically, and because the seed travels, that is rarely a simple procedure. Catching the problem early, or preventing contact altogether, saves your dog a great deal of discomfort.
Which dogs are most at risk?
Dogs with a long or dense coat are especially vulnerable, because seeds disappear into the fur unseen. Think of poodles, doodles, spaniels and shepherds. Breeds like these are popular among expat families in Amsterdam, and they need extra attention in summer. Dogs that walk regularly through tall grass, verges or the dunes are also at higher risk, regardless of coat type. If your daily route takes you through overgrown areas, it is worth being especially alert.
How clothing helps protect your dog
A grass seed can only attach itself if it can reach the coat or skin. A well-fitting suit made of smooth, tightly woven fabric takes that opportunity away: the seeds slide off instead of catching, and the vulnerable parts of the body stay covered. To be clear, no suit makes your dog completely immune, but a good protective suit is an effective remedy that significantly lowers the chance of a grass seed working its way in. It is a simple, preventive step that can spare your dog a trip to the operating table.
For this we stock the suits from Paikka. They were originally designed against insects and UV radiation, and they protect against grass seeds at the same time. The Paikka UV & Bug Overall covers the body and legs and offers the most complete protection. If you prefer something lighter, the Paikka UV & Bug Shirt is a good choice. You will find both in our Paikka collection.
More than grass seed protection: bugs, sun and cooling
The Paikka suits do more than guard against grass seeds, which makes them practical for the whole Dutch summer. The distinctive zebra pattern is not a style choice: the black-and-white stripes create an optical effect that disorients flying insects, so they are less likely to land on your dog. A plant-based GREENFIRST finish adds to that by helping to keep mosquitoes and insects away. The fabric also offers the highest UV rating, UPF 50+, which is welcome for dogs with a light or thin coat.
There is a cooling benefit too. Because the fabric is UV-resistant and quick-drying, you can dampen the suit on a warm day to give your dog some relief from the heat. The material is lightweight and stretchy so your dog can move freely, and the suits are machine washable at 30 degrees.
“Isn’t dressing a dog in summer unnatural?”
It is a fair question, and one we hear often, especially from owners used to a culture where dogs rarely wear clothing. Putting a suit on a dog when it is warm outside can look counterintuitive. The difference lies in the purpose and the material. This is not a thick jumper, but a thin, breathable, UV-resistant suit that actively protects against insects, sun and grass seeds. For a dog that would otherwise risk surgery for an embedded grass seed, that is a sensible, considered choice. We never sell anything that would burden your dog unnecessarily; if you are unsure, we are happy to think it through with you.
Frequently asked questions about grass seeds and protective clothing
When is grass seed season in the Netherlands?
Grass seeds are mainly a problem from late spring into late summer, roughly May through September. During those months the grasses dry out and the seeds break off. If you walk through tall grass, verges or dunes in this period, stay extra alert.
How do I know if my dog has picked up a grass seed?
Watch for sudden licking of the paws, head shaking, sneezing, or a swelling that does not go away. A grass seed under the skin is often invisible. If you are in any doubt, contact your vet: the sooner it is removed, the less it can migrate.
Does trimming the coat help against grass seeds?
A shorter coat makes seeds easier to spot and remove and can lower the risk, but it does not remove it, because the paws, ears and eyes stay exposed. Combining coat care with a protective suit works best. Our grooming salon is glad to advise you on this.
What size suit does my dog need?
For the Paikka suits the back length is the key measurement: measure from the base of the neck to the base of the tail. If you visit our shop on the Haarlemmerdijk, we will fit the suit together with your dog so the size is right.
Can I also use the suit against mosquitoes and sun?
Yes. The Paikka suits are designed against insects and UV radiation and protect against grass seeds as well, so the same suit serves you throughout the summer season.
