Can mushrooms kill dogs?

Mushrooms love the cooler Autumn weather and can appear suddenly after rainfall. Although commonly underestimated, mushroom intoxication ranks near the top of the list of pet poisonings every year. 

Signs that your dog may have eaten a mushroom are vomiting and diarrhoea  ( maybe with blood) which occurs within 6-12 hours of ingestion. These signs may go away, but unfortunately, your dog may not be in the clear. After about 48-72 hours following resolution of these signs, your dog will develop liver and kidney failure and the prognosis isn’t good at this point.

For this reason, I recommend regularly checking your garden for mushroom growth, particularly after damp, rainy days and removing any mushrooms you find (use gloves). And keep your eyes on your dogs whilst out walking for potential mushroom munching. 

Especially look out for the Death Cap mushroom which emits a fishy odour when it’s decaying which, for some reason is very appetising to dogs (and cats).  Death Cap can be identified by its yellowish-green cap that grows large and flat as the mushroom ages, ingestion is fatal.

If you think that your dog has ingested a mushroom, don’t delay please contact your veterinarian immediately for emergency care.

Better safe than sorry.
