Can Dogs Eat Mayonnaise?

The tangy smell and fatty contents of mayo are enough to make your dog beg. While mayo is dog-safe, you might want to think twice before letting them indulge.

Mayo doesn’t have anything harmful for dogs, making it safe for consumption. It’s essentially a mix of oil, egg yolks, and lemon juice, all of which are gentle on your dog’s tummy.

Mayo might have ingredients that are not harmful to dogs, but it’s still not 100% recommended. The one thing that owners should watch out for when feeding their dogs mayonnaise is the fat content. We’ll go into more depth about mayo below, providing the details of just how much is too much.

Is Mayo Good for Dogs?

While mayo might be packed full of things that are not harmful to dogs, it still has a lot of fat. Dogs can process fat just fine, though it’s large quantities that can be harmful. High doses of fat for your pooch could lead to a number of side effects, including upset stomach and inflammation.

Continued ingestion of foods that are high in fat is associated with:

  • Several cancers
  • Gastrointestinal diseases
  • Unhealthy weight
  • Pancreatitis

Though dogs seem like they can eat just about anything, too much of anything is no good. If they have indulged in mayo and you’re concerned, here is what you should do.

What to Do if your Dog Eats Mayo?

Dogs can get into everything, including condiments. If your pup had just a bit of mayo one day by accident, you’re not likely to see any symptoms. If they ingest too much at one time, you may see signs of discomfort or notice that your dog has excessive gas and bloating.

While small amounts here and there are okay, it’s large amounts that can be detrimental to health. Over time, the increased amount of fat could lead to the development of diseases and disorders. If your dog happens to ingest a lot of mayo, you should keep an eye on them to make sure they’re acting normal.

If you notice any changes or sudden onset of lethargy or signs of an upset stomach, you should give your vet a call, letting them know just how much mayo your dog had. For any sudden fainting or vomiting that won’t stop, it’s best to take your dog to the vet instead.

How Much Mayo Can a Dog Eat?

Like most human foods, dogs should enjoy mayonnaise in moderation. If your dog seems to love mayo and gets excited each time you pull it out of the fridge, it’s okay to give them a taste here and there. Try to limit their tastes to just once or twice a week, adding a teaspoon size to their food bowl.

When you do give them mayo, make sure there is plenty of time in between and that you only feed them very small, controlled amounts so that you don’t take it overboard.

Mayo Alternatives for Dogs

We like to give our pups the things that they enjoy. Sometimes, they crave more of something, even if it’s not the best thing for them. Instead of feeding them things that could be harmful to their health, you should shoot for yummy treats that won’t cause them harm. For some ideas, try these mayo alternatives.


Yogurt is creamy, tangy, and, if kept in the fridge, cool. This is the perfect treat for your pups, especially after a walk or run. Yogurt has a lot less fat than mayo and comes with a number of beneficial probiotics that help to keep your dog’s gut healthy.

If you want to try yogurt as an alternative, go for sugar-free, plain yogurt without any kind of added fruits or flavors.

Peanut Butter

It’s probably no secret, your dog loves peanut butter. There is something about the creamy and salty taste that makes it a dog’s favorite, though you should feed it to them sparingly. While it is lower in fat than mayo, there is a lot of protein, which could upset your dog’s stomach.

Add some to their favorite treats for an extra tasty snack or just scoop some out on your finger and let them lick away. When choosing peanut butter, go for those that have zero added sugars and contain only nuts and a bit of water.

Cottage Cheese (Low-Fat)

If your dog can tolerate dairy, cottage cheese is a great alternative to mayonnaise. It has similar fat content but is packed with lots of probiotics that help your dog’s digestive system. Since it also contains fat, you should refrain from feeding your dog too much and only feed them sparingly.

With Dogs, Moderation Is Key

If there is one thing that you should keep in mind as a dog owner, it’s that moderation is key. Don’t go overboard in feeding them anything and always be mindful of how often you feed them human food. Snacks and treats should be a very small portion of your dog’s food intake, not jumping over more than 10%.

Dogs who are fed a large amount of salty, fatty foods are at risk for a number of health problems, so it’s best to avoid them at all costs. If your dog is exceptionally small and thin, you want to pay even more attention to the things you put on their plate, as they can handle much less than an average or large-sized dog.

Final Thoughts

Mayo is a tasty treat that’s full of ingredients that are not harmful to dogs. While it may be tempting to share a bit with your pup, be mindful of the amount you give them, making sure to account for the fat content that comes with each bite.

If your dog does eat a large amount of mayo, keep an eye on them and watch for signs of discomfort. If you choose to give them a bit of mayo as a treat, do so, but in moderation, turning to other healthier alternatives when you can.
