Gradual weight loss is a common symptom of many different gut problems, such as chronic diarrhoea, protein losing enteropathy, stomach ulcers and IBD. Cancer Many types of cancer cause weight loss or muscle wasting, which can be gradual or very sudden. Diabetes is a condition that stops your dog being able to control their blood sugar levels, it causes rapid weight loss, changes in appetite, increased thirst, and is likely to make your dog pee a lot more than usual.

Most dogs lose a certain amount of weight as they age, especially as their muscles start to shrink. However, if your dog is losing a noticeable amount of weight as they age, it could be caused by something more serious so always have them checked by your vet.
