Can dogs eat marmite?

Not safe icon
No — far too salty

No. Marmite is extremely salty and often contains onion/garlic extracts. Even a small smear is too much sodium for a small dog.

The full picture

Marmite (and Vegemite, Bovril, and similar yeast extracts) is ridiculously salty — beyond what any dog should consume. It often also contains onion or garlic extract. Even a small smear on a plate is more sodium than a small dog should have in a day. Marmite toast or a dog licking a Marmite knife are all worse than most people realise.

If your dog has already eaten marmite

Marmite is very high in salt. If your dog has eaten more than a tiny amount, watch for excessive thirst and signs of salt toxicity. Call your vet if symptoms develop.
