Autumn Safety for Dogs: Avoiding Conker Risks.

Autumn is a wonderful season for long walks with your dog, crisp air, colourful leaves, and cosy evenings. But it also brings some hidden hazards, most notably, conkers.

Lucy Howells, a vet nurse at Butternut Box, explains what dog owners need to know to keep their furry friends safe this season.

Why Conkers Are Toxic to Dogs

Conkers may look harmless, but they contain aesculin, a naturally occurring toxin that can irritate a dog’s gut and, in larger doses, affect the nervous system.

Dogs are often drawn to the shiny, round seeds, which can look like toys or even treats.

Adding to the confusion, conkers look very similar to horse chestnuts — and while some edible chestnuts are safe for humans when cooked, these lookalikes can be dangerous for dogs.

If your dog eats a conker or shows any of these symptoms, contact your vet immediately:

  • Vomiting or retching.
  • Diarrhoea.
  • Excessive drooling or loss of appetite.
  • Abdominal pain.
  • Lethargy.
  • Rarely, more serious complications like intestinal blockages or nervous system effects occur and can cause seizures or tremors.

Even a curious nibble can make your dog unwell, so awareness is key.

Other Autumn Hazards to Watch Out For

Conkers aren’t the only autumnal dangers. Keep an eye on your dog around:

  • Acorns – high in tannins, which can upset the stomach and, in large amounts, affect kidney function.
  • Mouldy leaf piles – can contain mould spores that irritate the digestive system or airways.
  • Mushrooms – some species are highly toxic, and it’s often difficult to tell which are safe.

Being aware of these hazards helps you enjoy autumn walks while keeping your dog safe.

What to Do If Your Dog Eats a Conker (or Acorn)

If your dog has ingested a conker or acorn:

  1. Call your vet straight away for advice tailored to your dog. Provide details such as how many conkers your dog may have ingested, when it happened and any symptoms.
  2. Do not attempt to induce vomiting unless your vet specifically instructs you.
  3. Collect any samples or note how many were eaten — this helps the vet assess the situation.

Most cases are manageable with prompt attention, so try to stay calm and follow veterinary guidance.

Key Takeaways for A Dog-Friendly Autumn

Autumn is a season to savour with your dog. From colourful walks to cosy indoor snuggles.

Being aware is the key to keeping your dog safe. By paying attention during autumn walks, you can protect your pet and fully enjoy all the season has to offer.

With just a bit of extra care, you and your furry companion can make the most of autumn’s beauty, conker-free and worry-free.
