Here's why:
* High in Fat: Mayonnaise is extremely high in fat, which can lead to pancreatitis, a serious and painful condition in dogs.
* Onion and Garlic: Some mayonnaise contains onion and garlic powder, both of which are toxic to dogs.
* Salt: Mayonnaise can also be very salty, which can cause dehydration and other health problems in dogs.
* Potential for Allergies: Some dogs are allergic to eggs or other ingredients in mayonnaise, which could trigger an allergic reaction.
If your dog eats mayonnaise, it's important to watch them closely for any signs of illness. Contact your veterinarian immediately if you notice any of the following:
* Vomiting
* Diarrhea
* Lethargy
* Loss of appetite
* Abdominal pain
Remember: It's always best to stick to dog-safe foods and treats.
