What if my dog ate a wild mushroom?
No, toxic Treat it as an emergency. A few wild mushrooms, such as the death cap, can cause liver failure, and they are hard to tell apart.
Why
Only a small share of wild mushroom species are toxic, but those that are can be deadly, and even experienced foragers get them wrong (AKC). Death cap and similar Amanita species cause severe vomiting and diarrhoea, a false recovery, then liver failure. Others cause drooling, watery eyes, wobbliness, tremors or seizures. Some toxic species smell fishy, which may attract dogs. Australia's Animal Poisons Helpline says wild mushrooms are one of the most frequent reasons people call.
Signs to watch for
- Vomiting and diarrhoea
- Drooling or watery eyes
- Weakness and lethargy
- Staggering
- Tummy pain
- Seizures or coma
- Seeming better, then getting worse (a false recovery)
- Yellow gums or skin (jaundice, from liver failure)
If your dog ate wild mushrooms
Call your vet, emergency clinic or an animal poison line immediately. Do not try to identify it yourself. If you can, bring a sample wrapped in a damp paper towel inside a paper bag (AKC).
If your dog has eaten something toxic
