Pourquoi ?

Mayonnaise is primarily oil (fat) emulsified with egg yolk. It contains approximately 94 calories and 10g of fat per tablespoon, along with significant sodium. This fat density makes it a direct pancreatitis trigger — one of the most dangerous outcomes of dietary fat excess in dogs.

Most commercial mayonnaise contains vinegar and salt — the former can irritate GI mucosa and the latter contributes unnecessary sodium. Some mayonnaises add garlic or onion (aioli, garlic mayo) — these are additionally toxic.

A small accidental lick of plain mayonnaise is unlikely to cause serious harm in a healthy dog. But it should never be offered deliberately, and dogs known to be pancreatitis-prone should be kept away from any mayonnaise exposure.

Quelle quantité est dangereuse ?

Not chemically toxic in small amounts. Pancreatitis risk from fat content.

Quels sont les symptômes ?

DÉBUT :GI: within hours. Pancreatitis: 12–24 hours.
  • GI upset, diarrhea from excess fat; pancreatitis: vomiting, abdominal pain, lethargy

Que dois-je faire ?

Small accidental lick: monitor. Significant ingestion: contact vet, especially if the dog is pancreatitis-prone.

Can dogs eat tuna salad with mayo?

No — the mayo adds dangerous fat, and tuna salad typically contains onion, celery salt, and other seasonings. Plain canned tuna is a better option.

Is light mayonnaise safer for dogs?

Light mayo contains less fat but is still a high-fat, high-sodium food with no benefit for dogs. Often it also contains artificial additives or modified starches.
