Grass Ears in Dogs: Risks, Symptoms, Treatment and Preventive Measures

Dogs are natural adventurers, and their curious behaviour often carries unexpected risks. One such risk is the threat posed by grass awns, also known as 'creeping awns' or seeds with sharp points and barbs. Grass awns can easily become lodged in a dog's coat or skin and can even penetrate body orifices such as the ears, nose and paws. Although they may seem harmless at first glance, grass awns are dangerous: they not only cause localised irritation but can also lead to serious health problems such as infections, tissue damage and systemic complications.

Dog owners report hundreds of cases each year requiring medical intervention as a result of grass awns. Even a seemingly minor symptom, such as limping or a persistent sneezing fit, can be an indication of a grass seed in the body. This article discusses in detail the dangers of grass seeds in dogs, how to recognise symptoms, the necessary treatments and preventive measures. Through vigilance and the right actions, you can provide your dog with a safe and healthy environment.

What are grass awns and why are they dangerous for dogs?

Grass awns, also known as 'creeping awns', are the seeds of certain grass species that actively disperse during the summer months. These awns have sharp points and barbs that can easily become lodged in an animal's coat, skin and even in body orifices, such as the ears and nose.

What does a grass seed look like?

A grass awn has a spear-shaped structure with a sharp point on one end and a hairy or barbed structure on the other. They vary in size, from about 0.5 to 1.5 cm long, depending on the type of grass. The barbs ensure that they easily become lodged in a dog's coat and are difficult to spot with the naked eye.

Why do grass awns often get stuck in a dog's coat?

Dogs with long, thick or curly coats are at greater risk of grass awns. The rough texture of a grass awn catches on individual hairs, particularly in areas where the coat is less smooth, such as between the toes, in the ears, or close to the base of the tail. Active dogs that run through grass or bushes frequently are likely to pick up grass awns.

What makes grass awns harmful to dogs?

Due to their shape, grass awns easily penetrate the skin. Once under the skin, their backward-pointing barbs mean they can only move one way, forward, deeper into the tissue rather than working their way back out. This one-way movement is what lets awns migrate well beyond where they entered, and the external ear canal alone accounts for around half of all reported cases [1]. Grass awns in the ears, nose or eyes can cause more serious problems, such as hearing loss, breathing difficulties or even tissue necrosis.

What symptoms indicate a grass seed in a dog?

The symptoms of a grass seed infection depend on where the seeds are lodged or have entered. Here are some common signs for each area.

How do I recognise a grass seed in my dog's paw?

• Limping: A dog may have difficulty walking if there is a grass seed between its toes.
• Excessive licking: Your dog will lick the affected paw obsessively.
• Swelling: A swollen, red patch develops between the toes.
• Pain reactions: Your dog pulls the paw back or whimpers when touched.

What are the symptoms of a grass seed in a dog's ear or nose?

• In the ear: Your dog shakes its head constantly, scratches its ears, or tilts its head.
• In the nose: Frequent sneezing, nasal discharge and bleeding from the nose may indicate a grass seed in the nasal cavity.
• Audible discomfort: Your dog may make whining noises due to pain or irritation.

What signs indicate a grass seed that has burrowed deep into the skin?

• Abscess formation: A painful, swollen lump under the skin.
• Redness or pus: An inflammatory reaction with fluid or pus oozing from a small wound.
• Fever: If the immune system is struggling with the infection, your dog may become lethargic due to a fever.

What should you do if you discover a grass seed in your dog?

Acting promptly and carefully when dealing with a grass seed can prevent further complications. Here are some steps you can take.

Can you remove a grass seed yourself, and how do you do so safely?

You can try to remove a grass seed yourself if it is visible and has not yet burrowed into the skin. Use a pair of blunt-tipped tweezers and gently pull the grass seed in the opposite direction to where it entered. Ensure the seed is removed completely, without it breaking off.

Please note: If the grass seed is difficult to reach or is causing symptoms such as bleeding or swelling, it is important to consult a veterinarian immediately.

When should you visit the veterinarian for a grass seed?

Visit a veterinarian if:

• The grass seed cannot be completely removed.
• Your dog shows signs of pain, swelling or fever.
• The seed is lodged in sensitive areas, such as the ear, nose or eye.

What are the costs for the professional removal of a grass seed?

The cost of removing a grass seed varies depending on the complexity of the procedure. For simple procedures, you will usually pay between €30 and €100. For a complicated procedure, such as surgery under anaesthesia, the cost can rise to €300 or more.

Can a grass seed cause long-term damage in dogs?

If left untreated, grass seeds can cause serious health problems in dogs.

What complications can arise from grass awns in dogs?

• Chronic infections: Grass seeds can carry bacteria deep into the tissue.
• Organ damage: Grass seeds in the nose can migrate towards the chest and lungs in rare, serious cases [2].
• Tissue necrosis: Severe inflammation can lead to the death of affected tissue.

How do veterinarians prevent a grass seed from causing further infections?

Veterinarians first clean the wound and remove the grass seed completely. In cases of severe infection, antibiotics are prescribed, sometimes for several weeks. If necessary, the infected area is flushed to remove bacteria.

How long does it take for a dog to recover from a grass seed infection?

Recovery time varies from a few days to a few weeks, depending on the complexity of the case and whether treatment is administered promptly. Thorough aftercare and high-quality nutrition can help support recovery.

How can you prevent grass awns in dogs?

Prevention is the best strategy to minimise the risks of grass awns.

Why is regular checking of the coat important?

After every walk, inspect your dog's coat, especially the ears, paws and armpits. This helps to detect grass seeds before they cause discomfort.

What can you do during walks to avoid grass awns?

• Avoid tall grass or areas with dry grass.
• Use a dog harness or jacket to cover vulnerable parts of the body.

What preventive measures should you take during grass seed season?

Regular brushing removes grass awns from the coat. A visit to a groomer for a shorter coat further reduces the risk.

How does nutrition play a role in recovery and resistance to grass awns?

The right nutrition can strengthen a dog's body, both preventatively and during recovery.

What are the benefits of high-quality nutrition during recovery from a grass seed infection?

A balanced diet with the right nutrients supports the immune system and can help the body recover from inflammation and damaged tissue.

How can your dog develop stronger skin and coat with the right nutrition?

A diet rich in omega-3 fatty acids and vitamins, such as biotin and zinc, helps develop healthy skin and a strong coat. There's no direct evidence this stops grass awns from attaching in the first place, but a well-maintained coat is easier to check and groom, which makes awns easier to spot and remove before they can burrow in.

Can other animals also suffer from grass awns?

Grass awns are not only a danger to dogs; other animals and even humans can experience problems.

Are grass awns dangerous for cats?

Cats can also be affected by grass awns, usually around the paws or in the eyes. Symptoms such as excessive licking or swelling require immediate attention.

Can grass awns cause problems for humans?

Grass awns can cause injuries, particularly to feet or skin that comes into contact with tall grass. In humans, this often leads to splinters or minor infections.

Which animals are most at risk of grass awn-related problems?

In addition to dogs and cats, animals such as rabbits and horses are at risk, particularly due to their habitat in grassy areas.

With this comprehensive information, you can better understand and address the dangers of grass seeds. A proactive approach, from regular inspections to supporting your dog's skin and coat health, will help keep your dog protected and healthy.
