What’s Actually in Mayonnaise?

Mayonnaise is one the most popular condiments in America, so it’s only natural you will wonder can your dog have it too? Always when thinking about giving your dog something new, you should think what’s actually in it?

Mayonnaise is a heavily beaten product that is mixed with egg yolks, emulsion oil, and lemon juice or just vinegar.

The main component is oil, which makes it a massively fatty thing to eat for humans, mind dogs. Mayo’s fat content is roughly around 75%, with 65% of that being saturated fats, which is the bad fats. I can guarantee you; no veterinarian will advise or suggest you feed your dog such a high-fat content.

What you should also consider is that a lot of mayonnaise products contain soybeans, which a lot of animals can be allergic to or even sensitive too. If your dog has a soybean allergy, then you should never give your dog any mayonnaise. Always consult your local veterinarian if you’re worried or have any questions.
