Why It's Dangerous
Marmite (yeast extract) is extremely high in sodium, and a dog eating a meaningful amount straight from the jar can consume a concentrated dose of salt in a small volume.
Symptoms to Watch For
- Excessive thirst and urination
- Vomiting
- Diarrhoea
- Lethargy
- Seizures in severe, large-quantity cases
Vet Guidance
Contact your vet if a significant amount was eaten directly, given how concentrated the salt content is.
