If your dog ate moldy food, it’s important to know how to handle the situation. Moldy food can be toxic for dogs and cause them to become extremely ill. And even if your dog doesn’t have a reaction to it, the mold can still make them sick by causing gastrointestinal upset or diarrhea. There are three steps you need to take if your dog ate moldy food:

  1. First, check with your vet to see if they recommend anything else that might help your dog feel better more quickly than just waiting for the effects of the mold to wear off on their own.
  2. Next, remove any remaining pieces of moldy food from their stomach as soon as possible so that they don’t eat any more and get sicker than they already are (or die!). If there isn’t much left but you still want to remove it all right away, try giving them some Pepto-Bismol or activated charcoal (both available without prescription) mixed into water or milk until they throw up what little there was left in their stomach already—then wait at least an hour before giving them anything else from now on!
  3. Finally, monitor closely for signs of -Vomiting -Diarrhea -Lethargy -Abdominal pain

Eating moldy food is more than just ‘gross’ it can actually make a dog critically unwell. This is especially true if a dog ingests a large quantity of gone off food. Dogs eat moldy food when they raid the trash, scavenge for food outside or eat their own food that was left out in the heat for too long. I’ve even treated one Labrador who had raided its owners compost heap.

Signs of mold toxicity can include vomiting, diarrhoea, lethargy, muscle tremors, fever, confusion and seizures. Signs tend to develop within a few hours.

Time is of the essence when it comes to mold toxicity and the sooner a pet can be seen by their vet, the better. With early treatment, the prognosis is good for most dogs. Sadly, in severe cases of mycotoxicity, delaying or withholding treatment can mean the patient passes away.

Treatment consists of eliminating the mold from the body, which may mean inducing vomiting, a gastric lavage and/or feeding activated charcoal. We also provide supportive care in the form of e.g. fluids, anti nausea medicine and anti seizure medicine as needed.

Moldy food can cause a big problem in your house if eaten by your dog. The mold we see in food is a fungus and most of them cause several health problems when ingested.

If you have found your dog eating a piece of moldy food or if you find your dog’s food is moldy and have already fed them with it, call your vet immediately. The sooner the better, as you will have less time for the symptoms to kick in and more chances of your dog undergoing less severe treatments.

If you can, take the food your dog was eating to the vet too so they can test it in the lab to find out what kind of toxin they are dealing with.

The consequences of your dog eating moldy food can be life-threatening, as most neurotoxins in moldy food can cause nausea, dehydration, vomiting, tremors, and even seizures.

It is critical that you contact your vet as soon as possible, they are the only ones that can tell you what to do next. Don’t try to induce vomiting or fed them any kind of homemade remedies, as you don’t know the effects and the type of neurotoxin your dog has ingested. Don’t leave your dog unattended after eating moldy food.

Under the supervision of a vet, a dog that ate moldy food can return to everyday life with no problems as most dogs survive this type of food poisoning.
