Autumn is a beautiful season to get outside with your dog, with crisp air, colourful leaves, and woodland walks at their best. But hidden among the beauty are hazards that can put your pet at risk.
Mushrooms, acorns, and damp leaf piles may look harmless, yet they can cause serious health problems for dogs. By being aware of these seasonal dangers, you can keep autumn walks safe and enjoyable for your four-legged friend.
Why autumn brings hidden risks for pets
As the weather changes, natural environments shift. Wet, decaying leaves, fallen tree nuts, and wild fungi thrive in autumn conditions. While dogs are naturally curious and may enjoy sniffing, licking, or chewing what they find, some of these substances are toxic. Even small amounts can cause illness, making vigilance on walks essential.
Mushrooms – not all fungi are safe
Wild mushrooms pop up across parks, gardens, and woodlands in autumn. Some are harmless, but others are highly toxic. Unfortunately, it’s nearly impossible to distinguish safe mushrooms from poisonous ones without specialist knowledge.
Toxic effects of mushrooms can include:
- Vomiting and diarrhoea
- Drooling and abdominal pain
- Tremors, seizures, or collapse in severe cases
Practical tips:
- Do not allow your dog to eat or chew wild mushrooms.
- Stay alert during walks and steer clear of areas with visible fungi.
- If your dog eats a mushroom, contact a vet immediately – take a photo of the mushroom if possible.
PawSquad’s 24/7 Vet Consults are available anytime if you are unsure whether your pet has eaten something dangerous.
Acorns – tempting but toxic
Acorns often fall in abundance from oak trees during autumn. Many dogs find them appealing to chew or play with, but acorns contain tannins that are toxic when ingested.
Risks include:
- Vomiting and diarrhoea
- Abdominal pain and loss of appetite
- In severe cases, kidney or liver damage
Acorns can also cause choking or intestinal blockages if swallowed whole.
Keep your dog away from oak trees and fallen acorns. If your pet manages to eat one, consult a vet as soon as possible.
Leaf mold and damp piles of leaves
Jumping into leaf piles may look fun, but damp and decomposing leaves harbour mould and bacteria. These can cause stomach upsets if eaten and may trigger respiratory irritation, particularly in dogs with pre-existing conditions such as asthma-like symptoms or allergies. Wet leaves also conceal sharp sticks or hidden debris that can injure paws.
Tips to stay safe:
- Avoid letting your dog rummage or play in large, damp piles of leaves.
- Rinse paws after walks to remove dirt, mould spores, or hidden irritants.
- Provide safe toys at home for play instead of relying on risky outdoor piles.
Extra seasonal tips for autumn safety
Beyond mushrooms, acorns, and leaf mould, there are a few other seasonal hazards to keep in mind:
- Conkers: Like acorns, horse chestnuts can be toxic and cause blockages.
- Slugs and snails: More common in damp weather, these can carry lungworm, which is dangerous to dogs.
- Cold mornings: Older pets with arthritis may find mobility harder as temperatures drop – Mobility Care support can help keep them comfortable.
Supporting your pet’s health through autumn
Autumn walks don’t need to be risky if you stay alert and plan ahead. A little prevention goes a long way.
- Carry fresh water and safe treats to distract your dog from scavenging.
- Keep them on a lead in high-risk areas such as woodlands.
- Make regular use of PawSquad’s Health & Happiness Tools to monitor your pet’s wellbeing through seasonal changes.
- Speak to vet about parasite control and how common lungworm is in your area. There are interactive maps available for lungworm risk.
- Be aware of the risk of Harvest mites at this time of year. Speak to a vet if you think your pet may have mites.
- Be aware of the risk of ticks at this time of year. Speak to a vet if unsure how to remove a tick.
Did you know?
Alabama rot, while rare, is more common in autumn, and can be fatal if left untreated. Wash your dog after walks, check for any unusual skin sores appearing and seek veterinary advice.
