Why can mushrooms and fungi be dangerous for dogs?

September to November is peak mushroom season in the UK, and whilst they are nice to see on a winter walk - they are incredibly dangerous and in some cases fatal to dogs. 

RSPCA dog welfare expert and veterinary nurse, Lauren Bennett, said: “While most species of mushrooms and fungi are completely harmless to our dogs, there are some that can be toxic and, if eaten, could make your dog seriously ill. 

“If your dog eats things off the ground when out walking then we’d advise avoiding damp, warm, wooded areas where there are lots of fungi.

"Teach them a ‘drop’ or ‘leave’ command to ensure they leave something alone when told; and keep dogs on the lead in any high-risk areas where mushrooms are visible.

"We’d also advise removing mushrooms from your garden.

“Symptoms that your dog may have eaten a toxic mushroom can include excessive drooling, a loss of coordination, vomiting, diarrhoea, weakness or collapse, and seizures.

"If you have any concerns that your dog has eaten something dangerous please seek veterinary advice urgently.”

A spokesperson for Kennel Store added: "Take a picture or, if possible, take a sample of the mushroom that has been eaten so your vet has an idea of what your dog has eaten and how to proceed with treatment. 

"You may not see your dog eat a mushroom. If you notice neurological signs, agitation, vocalisation (different to normal) or odd behaviours following a walk, take your dog to the vets. 

"Symptoms can be frightening so it’s important to stay calm and act quickly.”
