If all your dog ate was one oreo, chances are they’ll be ok. However, any time your dog eats something they’re not supposed to, it’s a good idea to call your vet and get their advice. In this case, they’ll most likely suggest monitoring the animal at home, but it’s always a good idea to get a professional opinion.

Dangerous: This food is generally considered a serious threat to the health and wellbeing of dogs. Please contact your vet, a veterinary hospital or pet poison control if you suspect your dog has eaten this food recently.

What happens if your dog eats an Oreo?

The first thing you’ll want to do is remove the Oreos from your pet to prevent them from eating any more. Then you should try to ascertain just how many cookies they’ve eaten. You’ll also want to check the packaging to see if they’ve ingested any of that. Sometimes eating the packaging can cause more problems, such as gastrointestinal blockage, than the cookie(s) itself. Call your vet and keep an eye out for any unwanted side effects (see the list further down in this article).

If you’re not sure if your dog has eaten an Oreo, consider feeding them a bland diet of chicken and rice for a day or two. Make sure they have plenty of water and access to the outdoors to use the restroom. Most likely they’ll present negative symptoms within 48 hours, if they’re going to happen.

Are Oreos toxic to dogs?

Oreos contain chocolate and chocolate is toxic to dogs, due to the substance theobromine which can be found in cacao. Theobromine can cause hyperactivity, upset stomach, nervous system problems and heart issues in dogs. Depending on how much the dog has eaten compared to its size, it can even cause death.

The good news is, there is very little theobromine present in Oreos. Oreos are mostly made up of sugar, flour, oil and chocolate flavoring.  Your dog is more at risk of getting fat from eating Oreos than they are at risk of getting seriously ill. Again, this is still dependent on the amount of Oreos they’ve eaten compared to how big or small they are, so you should always contact your vet to determine a plan of action.

Are ‘Golden Oreos’ ok for dogs to eat?

Golden Oreos are the non-chocolate version of Oreo cookies. Although they don’t contain chocolate, you still should not feed them to your dog as a treat. They’re very high in sugar and fat, and they are difficult for your dog to digest. They can also lead to weight gain which could cause your pet other health problems down the line.

Symptoms to watch out for:

Eating a single Oreo may not cause symptoms, but some dogs (and people!) don’t know how to stop at just one. If your pup eats several cookies, there will be cause for concern. You’ll need to drop any plans you have and monitor them for the following symptoms:

  • Vomiting
  • Diarrhea
  • Lethargy
  • Panting
  • Restlessness
  • High heart rate
  • Seizures

The best thing you can do is make sure your dog doesn’t have access to food, like Oreos, that could potentially cause them harm. Keep food stored on high shelves, or behind locked cabinets and pantry doors. If you know your dog is a counter-surfer, take care to not leave food out in the open. Make sure trash can lids are locked and/or take garbage containing food debris directly outside.
