    There are a lot of reasons an old dog might start losing weight. It could be a result of natural changes to their metabolism and hormone levels as they get older, which simply means a bit of a change in diet is in order.

    However, it could also be a symptom of a medical condition that requires treatment.

    Dogs will often go off their food if it is painful for them to eat, either because of dental problems or joint problems that mean their bowl is difficult to access.

    A change in their eating arrangements could get them eating normally again.

    However, a variety of serious medical conditions can also put them off their food or leave their body unable to properly produce energy from food, and therefore, rely on fat stores instead.

    Examples of this include diabetes, kidney disease, and heart disease. These will usually be accompanied by other symptoms, which will help you make a diagnosis with your vet.
