Can Dogs Eat Mayo? (The Short Answer)

No, dogs should not eat mayo.  Just like with humans, mayo provides virtually no significant health benefits while racking up the calories and fat.  Dog’s digestive systems don’t bode well with large amount of high-fat foods.  Most mayos also include at least some lemon juice, which isn’t safe for dogs.  If your dog does get a taste of mayo on accident, there is no need to panic as it is not toxic, just rather unhealthy. 

It’s important to remember, that even with the best of intentions, accidents happen and dogs can easily eat things they shouldn’t.  Unfortunately, even if those accidents aren’t fatal, they can result in huge, unexpected veterinary expenses.  That’s why we recommend all responsible dog owners get a free, online pet insurance quote from Healthy Paws.

No, mayo really isn’t good for dogs.  The negatives greatly outweigh any positives in terms of nutrition. 

Some could argue that there are some minor benefits to mayo, which include the presence of vitamins and minerals.  Remember, these are important, but the negatives of mayo do not justify feeding your dog mayo to get these few vitamins.  All of your dog’s essential vitamins and minerals should already be consumed in their daily meals of dog food.

Is Mayo Bad for Dogs?

We’ve already answered the question, “can dogs have mayo?” Now, let’s learn about the dangers of feeding your dog this food! Is mayo bad for dogs?

Mayo is bad for dogs.  While it isn’t toxic, it is rather unhealthy.  If your dog does happen to eat some, they should be fine and at worst develop a belly ache.  If they ingest a really large quantity, you should contact a veterinarian.

In 1 tablespoon of mayo there are 94 calories and 10 grams of fat!  Dogs don’t need as many calories as humans, especially smaller dogs.  Just 100 extra calories from a tablespoon of mayo could cause them to gain weight if given consistently.  Just like with humans, maintaining a healthy weight is critical in preventing dogs from experiencing countless health issues. 

High-fat foods can create serious complications over time.  High-fat foods cause the pancreas, a small organ that secretes digestive enzymes to help break down fats, to go into overdrive.  This organ working so hard to digest excess fat causes it to become inflamed.  The main signs associated with inflammation include redness, swelling, heat, pain, and loss of function. You can imagine how detrimental these would be to an essential organ.  If the pancreas works too hard for too long it can be considered pancreatitis.  At times it can be difficult to say no to those adorable puppy eyes when they’re begging for food, but it’s better to refuse them a bite of food now to prevent them from developing health issues in the future. 

A lot of store-bought mayo products are made with soy.  A lot of dogs have a sensitivity or allergy to soy.  It’s important to check the ingredients to see if the mayo you bought has soy, and to be aware of whether your dog has any problems with soy.  If your dog does have issues with soy products and they manage to eat a soy-based mayonnaise, you should contact a veterinarian. 

In most mayo recipes, store bought or homemade, an ingredient is lemon juice.  While lemons are not necessarily toxic, they’re not safe for dogs.  Read our article for more: Can Dogs Eat Lemons?
