Dear DCVS Clients,

PLEASE SHARE.

I noticed the yard mushrooms really popping up yesterday with the heat. So it's time for my annual reminder!!

While some species don't cause harm, MANY SPECIES OF MUSHROOMS ARE TOXIC to dogs and can cause neurological issues and even irreversible liver failure. Identification of mushroom types is very difficult, and the time spent deciding if a consumed mushroom is toxic is time wasted. Dogs will eat anything and everything, especially puppies. So today, peruse your yard, remove any mushrooms you find, and dispose of them in a trash can your pet has no access to. This is also a great time to remind our DCVS dog owners that everyone should always keep fresh, unopened hydrogen peroxide in the house.
If your dog eats a mushroom from your yard, I want you to induce vomiting immediately (awake and alert animals only). Signs and symptoms of toxicosis can occur as soon as 1 hour after ingestion with some species, so please don't waste time trying to identify the mushroom type beforehand. Identifying mushroom species can be tricky and is a skill few people have. Give fresh hydrogen peroxide (3%) orally at 1ml/ lb of body weight (I usually cap this out at 20-25cc in big dogs). After giving the hydrogen peroxide, take them for a walk. If they haven't vomited within 10 minutes, repeat the hydrogen peroxide. Inspect the vomit for mushroom pieces and ensure it looks like all the pieces are there. Preferably, we see vomiting until it's clear liquid or bile to ensure we've emptied the stomach completely.
If they still haven't vomited after two doses of hydrogen peroxide, current clients should call us and use the emergency extension. Save the pieces for possible identification. If there are other intact mushrooms, save a few for this same purpose.

Non-clients should contact their regular veterinarian for advice.
