Many pet owners are tempted to share their food with their dogs, but not all human foods are safe for canine consumption. Mayonnaise may seem harmless due to its mild flavor and creamy texture, but it is not a suitable treat for dogs. Mayo can pose several health risks, especially if your dog eats it in large quantities or on a regular basis.
Mayonnaise is high in fat and calories, which can contribute to weight gain and digestive problems in dogs. Some varieties of mayo also contain ingredients like garlic and onion, which are toxic to dogs and can cause serious health issues. Before offering your dog any food containing mayonnaise, be aware of these risks and monitor your pet for any symptoms of illness.

Only offer mayonnaise as an occasional treat, and do not make it a regular part of your dog’s diet.
