Autumn walks: conkers, acorns, fungi and seasonal canine illness
Autumn woodland walks are a highlight for many dogs, but this is also the season for conkers, acorns, wild mushrooms and a rare condition called seasonal canine illness.
Conkers and acorns
Conkers contain a toxin that can cause vomiting, diarrhoea and tummy pain, and their size and hard shell mean they can also block the gut. Acorns contain tannins that upset the stomach and, in larger amounts, can affect the kidneys. Discourage chewing and picking them up, and do not use them as toys.
Wild mushrooms and fungi
Some wild fungi are harmless and some are deadly, and it is very hard to tell them apart. If your dog eats an unknown mushroom, contact your vet straight away and, if you can, take a photo or sample with you.
Fallen fruit
Windfall apples and other fruit can ferment on the ground, and eating lots can upset the stomach. Fruit stones and pips are a blockage risk.
Seasonal canine illness (SCI)
SCI is an uncommon illness seen mainly between August and November, in dogs that have walked in woodland. Signs usually appear within 24 to 72 hours of the walk and include sudden vomiting, diarrhoea, lethargy, tummy pain and trembling. The cause is still not known, though harvest mites have been suggested as one possible factor. Most dogs recover well with prompt vet treatment, so speed matters.
Harvest mites
These tiny orange mites are common in late summer and autumn, often between the toes, around the ears and on the belly, and cause intense itching. Ask your vet about suitable preventive treatments.
After an autumn walk: keep an eye on your dog for the next few days, and tell your vet you have been in woodland if they become unwell.
When to contact your vet
- Vomiting, diarrhoea or lethargy within a few days of a woodland walk.
- Your dog has eaten wild mushrooms, a large number of acorns, or swallowed a conker.
- Intense itching, sores or orange specks on the skin.
