Yes, dogs can eat Vegemite, but only in very small amounts and occasionally. It is not toxic to dogs and contains beneficial B vitamins like B1, B2, B3, and B9. However, Vegemite has a very high salt content, which poses health risks such as sodium ion poisoning, dehydration, high blood pressure, and kidney damage if consumed in large quantities or regularly. Some dog owners use a small dab of Vegemite to help give their dogs medicine because its strong taste masks the medicine and its sticky texture helps the dog swallow pills more easily. It is best to consult a veterinarian for advice on safe amounts depending on the dog's size and health condition. Overall, Vegemite should only be given as an occasional treat, not a regular part of a dog's diet.
