When dogs develop diabetes » Guide

In healthy people, the body produces insulin, which helps to process sugar. People with diabetes, however, produce no insulin or too little. This is due to a particular organ, the pancreas, which no longer works properly. All other mammals have a pancreas too, which is why our pets, such as dogs, cats or guinea pigs, can also develop diabetes.

Signs of diabetes in dogs and diagnosis

Diabetes in dogs is not easy to recognise at first, because the symptoms can develop gradually. Early detection is essential, however, to prevent damage to organs and blood vessels. Typical signs include:

• Increased thirst, often the first sign that owners notice
• Frequent urination due to the raised blood sugar level
• Weight loss despite a good appetite, because fat and muscle are broken down
• Weakness and tiredness, because the body cannot use energy properly
• Clouding of the lens of the eye, which can lead to blindness if left untreated

These signs should be taken seriously and a vet should be consulted. A simple blood test and a urine test usually confirm the suspicion of diabetes, because they reveal the raised blood sugar level. Further tests may be needed depending on the individual diagnosis.

Treatment

Treating diabetes in dogs follows the same approach as in humans: giving insulin. Today insulin can be given as injections to regulate the blood sugar level. The vet usually draws up a precise insulin plan tailored to the individual needs of the dog. Blood sugar can be measured with a meter using a drop of blood from the ear. The insulin dose is essential and must be followed very precisely to avoid low blood sugar.

Nutrition and diet management with diabetes

Alongside insulin therapy, nutrition plays a central role. A stable diet is crucial to keep the blood sugar level steady and to minimise the risk of fluctuations. A canine nutrition adviser can be helpful here, as dogs with diabetes have specific nutritional needs. The aim is a balanced diet that is high in fibre, low in sugar and contains adapted amounts of protein and fat.

Conclusion

Diabetes in dogs requires attentive care and regular adjustment of the treatment. In addition to the daily insulin and blood sugar checks, a suitable diet and support with vitamins play an important role in wellbeing. Vitamin B can help to make up for nutrient deficits and keep the dog fit. Especially with older dogs, it is important to always see the vet if there are symptoms such as great thirst or sudden weight loss, so that an accurate diagnosis can be made and action taken early.
