Everything You Need to Know About Autumn Hazards for York Dogs

Autumn in and around York is a beautiful season for a dog walk, all crunchy leaves and low golden light, but the ground underfoot changes and brings a fresh set of hazards worth knowing about. Conkers and acorns, fallen fruit and autumn fungi all appear as the weather turns, and most are toxic or dangerous to dogs if eaten. Here is everything you need to know to enjoy the season safely, from what to watch for on the walk to when to ring your vet.

None of this should put you off autumn walks. It is simply about being a bit more aware of what your dog is picking up, because the classic autumn dog emergency is the one that starts with a mouthful of something off the ground.

Conkers and acorns

These are the big two, and they turn up everywhere from October: parks, verges, pavements and gardens across York.

• Conkers fall from horse chestnut trees. They contain a toxin called aesculin, and eating them can cause vomiting, diarrhoea, drooling and a very upset tummy. Their size also makes them a genuine choking and blockage risk, especially for smaller dogs.
• Acorns fall from oak trees and are toxic too. They can cause stomach upset and, in larger quantities, more serious problems, along with the same choking and blockage risk.

Dogs Trust has a helpful piece on both, and the short version is simple: do not let your dog chew or swallow either, and speak to your vet promptly if they do.

Fallen fruit

Autumn brings windfall apples, plums and other fruit down in gardens and on verges. A little apple flesh is not the issue, but:

• Stones and pips from plums, apricots, cherries and apples are a choking and blockage risk and are best kept away from dogs.
• Fermenting windfalls left on the ground can start to ferment, and a dog gorging on them can effectively get alcohol poisoning, as well as a bad stomach upset.

If you have fruit trees at home, clearing the drops regularly is the easiest fix.

Autumn fungi

Mushrooms and toadstools spring up overnight in damp autumn weather, on grass, under trees and in leaf litter. Some are harmless and some are seriously toxic, and the honest truth is that even experts struggle to tell them apart at a glance.

Worth knowing: Because you cannot reliably tell a safe wild mushroom from a dangerous one on sight, the only safe rule is to stop your dog eating any of them, and treat any suspected ingestion as urgent.

If your dog does eat a wild mushroom, do not wait for symptoms. Try to safely photograph or bag a sample to show the vet, and ring for advice straight away.

Other autumn odds and ends

A few smaller ones round out the season:

• Rotting leaf piles can harbour bacteria and mould, and some dogs love rummaging and eating from them.
• Slug and snail pellets and their contents become more common as gardeners protect autumn planting, and some are toxic.
• Darker walks mean more roadside time, so a light or reflective collar is worth it.

For any suspected poisoning, Animal PoisonLine on 01202 509000 can advise on whether a trip to the vet is needed.

Where grooming fits into autumn

Autumn is peak season for coats picking things up. Wet leaves, mud and burrs cling to feathering, and a damp, dense coat left unattended is where matting sets in fast. A well-maintained coat dries quicker, sheds mud more easily and lets you spot burrs and debris before they become a knot. If your dog is coming home soggy and mucky most days, a sensible autumn trim keeps things manageable. Our grooming prices and packages page shows the options, and I am always glad to advise on what suits your dog's coat.

Frequently asked questions

Are conkers poisonous to dogs? Yes. Conkers contain a toxin called aesculin that causes vomiting and tummy upset, and their size makes them a choking and blockage hazard. Speak to your vet promptly if your dog eats or chews one.

My dog ate an acorn, what should I do? Acorns are toxic and can also cause a blockage, so ring your vet for advice rather than waiting. Vets Now has clear guidance on what to do. Try to estimate how many were eaten.

Are wild mushrooms dangerous for dogs? Some are seriously toxic and some are harmless, but you cannot reliably tell them apart on sight, so treat any mushroom your dog eats as an emergency and contact your vet.

Is fallen fruit a problem? It can be. Stones and pips are a choking and blockage risk, and fermenting windfalls can cause alcohol poisoning as well as an upset stomach. Clearing drops at home is the simplest prevention.
