Why is Blue Cheese Bad for Dogs?

Blue cheese contains mold cultures that produce roquefortine C, a toxic substance for dogs. When ingested, this compound can cause serious neurological issues, including tremors and seizures. Additionally, the high-fat content in blue cheese can lead to pancreatitis, a painful and potentially life-threatening condition.

How Much Blue Cheese Can Dogs Eat?

Simply put, no amount of blue cheese is safe for your dog. If your dog accidentally consumes a small piece, it’s less harmful, but it’s still a good idea to watch for any adverse reactions. Even a little blue cheese can upset your dog’s stomach, so it’s best to keep it off their menu entirely.

Common Misconceptions

Some people believe that because dogs can eat small amounts of certain cheeses, all cheeses are safe. This isn't true. While plain cheese in moderation might be okay, blue cheese is particularly dangerous due to its toxic mold content. Don’t assume what's safe for you is safe for your pup.

Similar Harmful Products

It's not just blue cheese you need to worry about. There are other similar types of food that can also be harmful to your dog:

  • Roquefort: Contains roquefortine C, just like blue cheese.
  • Gorgonzola: Another blue cheese variant that poses the same risks.
  • Stilton: A crumbly cheese that's equally dangerous for dogs.

Related Foods to Avoid

  • Cheese spreads containing blue cheese: Check the ingredient list.
  • Mixed cheese platters: They might contain small amounts of blue cheese.
  • Dressings or sauces with blue cheese: Often overlooked, but equally risky.

What to Do If Your Dog Eats Blue Cheese?

If your dog eats blue cheese, stay calm but act quickly. Remove any remaining cheese, and try to gauge how much was eaten. Contact your vet immediately for advice. Do not induce vomiting unless directed by your vet, as this can cause more harm than good.

In the long term, ingesting harmful foods like blue cheese can lead to serious health issues and costly treatments. Neurological damage or pancreatitis might necessitate ongoing treatment, which can be expensive. Pet insurance can help manage these costs and provide peace of mind during emergencies.

What are Healthy Alternatives?

Looking for safe and tasty options for your dog? Consider these alternatives:

  • Plain cooked chicken: High in protein and easy to digest.
  • Carrot sticks: Crunchy, nutritious, and loved by many dogs.
  • Apple slices: Just be sure to remove the seeds and core.


Bottom line: blue cheese is a big no-no for dogs. Keep it away from your furry friend to avoid potential health risks. Always consult with your vet if you have questions about your dog's diet or if they consume something they shouldn't. Taking these precautions ensures your pup stays happy and healthy!
