Fiona Firth, head nutritionist at Burns, said diet awareness was important to prevent development of diabetes and to help dogs already suffering from the disease.
"Diabetes in dogs has increased dramatically in recent years," she said.
"The reasons for this are unclear, but chronic inflammation is an important cause. The origin of this, as with many chronic illnesses, is incorrect diet. Dogs who are obese are at a far higher risk of diabetes.
"As certain breeds are more likely to develop it, there is thought to be a genetic component to this disease as well. Some autoimmune diseases can damage the pancreas resulting in diabetes."
Symptoms of diabetes include weight loss, changes in appetite, increased urination, lethargy, excessive thirst, and urinary tract infections. If you're worried about any of the signs visit your vet.
