While vomiting is a common initial symptom, it is essential to understand the potential risks and take appropriate steps to ensure your dog’s well-being. Read below to explore the effects of moldy food on dogs, the symptoms to watch out for, and what immediate actions you can take to help your furry friend recover. 

Toxic Terrors: Unveiling the Dangers of Moldy Food 

Being aware of what your dog eats is crucial for their overall health and well-being. Toxic items, such as moldy food are a common concern amongst pet owners and it's important to know how mold can affect dogs. Moldy food can be found in various places such as garbage, pantries, refrigerators, or compost bins. Common foods that can get moldy include cheese, bread, and nuts. The concern arises from the presence of tremorgenic mycotoxins produced by fungi, which can lead to neurological issues in dogs. Ingestion of aflatoxin, a type of mycotoxin, can result in liver failure.

If your dog has ingested moldy food, you must seek medical help immediately. Start by calling Pet Poison Helpline at (855) 764-7661 and your veterinarian for first aid advice.

The specific treatment approach will vary depending on when and how much mold your dog ingested. Remember, taking precautionary measures such as promptly discarding any moldy food and regularly inspecting your home for mold growth can help prevent mold poisoning.
