What to Do If Your Dog Has Mushroom Poisoning

If you think your dog is experiencing mushroom poisoning, contact your veterinarian right away. You can also contact the ASPCA Animal Poison Control Center at (888) 426-4435 24 hours a day, 365 days a year for assistance if you believe your pet has ingested a toxic mushroom or any other poisonous substance.

Treatment for your dog’s mushroom poisoning depends on the type of mushroom your dog ate, which is why it’s helpful if you can bring a sample of the mushroom (handle with gloved hands and wrap in a damp paper towel) to your veterinarian. How recently your dog ate the mushroom also is a treatment determining factor.


Precautions

Always stop dog from eating mushrooms if you’re not sure of the mushroom’s safety or if it’s a mushroom found in the wild. According to the ASCPCA, “As with most poisonings, the best method of controlling mushroom poisonings is preventing exposure…Dogs should be prevented from consuming mushrooms or roaming when they are being exercised.”

Unless you are a mycologist (fungi expert), avoid trying to identify the toxicity of a mushroom. Be on the safe side and bring your dog in to the vet if it has consumed a wild mushroom or exhibits symptoms of mushroom poisoning.
