Tuna and mayo isn’t “toxic” to dogs but that doesn’t make them healthy either. Here are the reasons why you should avoid feeding your dog anything that contains tuna and mayo, including salads, pasta, and sandwiches.

Why tuna and mayo is bad for dogs

Mayonnaise is bad for dogs due to having a high fat content. Dogs that eat a high-fat diet are prone to developing serious health conditions like pancreatitis later on. In terms of immediate effects, dogs with sensitive stomachs may suffer from clinical signs like vomiting and diarrhea because their body can’t deal with the high fat content.

Tuna should also be avoided because it is known for having one of the highest amount of mercury among all edible fish species. Feeding tuna infrequently and in small amounts is unlikely to cause much harm but the last thing you would want is for the level of mercury to build up over time in your dog’s body. That can happen if you let your dog eat meals like tuna and mayo on a regular basis.

There is also the concern of supplementary ingredients that goes into meals like tuna and mayo salad. Some recipes may utilize ingredients that are toxic to dogs, such as onions and garlic.
