Avoid routine mayonnaise feeding and skip flavored versions entirely. The high fat content may cause GI upset or pancreatitis in sensitive pets. Flavored aioli with garlic or onion adds further risk.
Mayonnaise is a creamy oil-and-egg emulsion made with vinegar or lemon juice, used in sandwiches, potato salad, tuna salad, dips, and dressings.
Store-bought mayo is pasteurized and stable when sealed; homemade versions use raw egg and spoil faster. Flavored mayos include garlic, onion, chili, mustard, or sweet additions.
Mayo often appears mixed into leftovers, burger sauces, and salad coatings where quantity is hard to judge. Even small spoonfuls can be rich for pets with fat intolerance.
