Recent weather conditions have resulted in heavy mushroom sprouting in a number of areas. While not all mushrooms are toxic to dogs, some can be extremely dangerous and even deadly if ingested. 
The severity of toxicity can depend on the type of mushroom ingested, the amount ingested and the size of the dog. Symptoms of mushroom toxicity can include vomiting, diarrhoea, abdominal pain, weakness, lethargy, seizures and even death.
There are many varieties of mushroom that can be toxic, but the particularly deadly Death Cap Mushroom (Amanita phalloides) should be specifically avoided – it is a known cause of acute liver failure in both people and pets. Death Cap Mushrooms typically have sticky yellow or green tinted caps with crowded white gills underneath. Mature death caps are wide and nearly flat on top, whereas immature death cap mushrooms have a very rounded cap. These mushrooms are commonly found beneath pine, oak and other broad-leaved trees, but locations can vary.
To prevent mushroom toxicity in dogs, it is important to keep your dog away from any wild mushrooms that may be growing in your yard or on walks. Always keep your dog on lead when out for a walk and check your yard daily, removing any mushrooms or fungi. If you are uncertain about the type of mushroom your dog has consumed, it is best to assume that it is toxic and seek veterinary care immediately.
If you suspect your dog has ingested a toxic mushroom, it is important to seek immediate veterinary attention. Your veterinarian may induce vomiting to remove any remaining mushrooms from the stomach, provide supportive care such as IV fluids and medications to manage symptoms, and monitor your dog’s condition closely. In severe cases, hospitalisation may be necessary.
