Should potatoes be part of a dog's diet?

Many people believe that potatoes are harmful to dogs, but not all potatoes are alike! Only raw unpeeled potatoes are toxic because of the solanine they contain in their raw state. Not even boiled potatoes are entirely suitable for dogs, as they digest potato starch poorly and they could cause intestinal problems in large quantities.

So why do potatoes appear in high-quality dog food? The key is the way in which they are processed - extrusion (simplified processing at high temperature and pressure). This radically reduces the content of antinutrients and natural toxins. This means that the dog only gets the valuable and highly digestible components from the potatoes. 

The digestibility of starches after extrusion is even similar to the digestibility of animal proteins. In addition, potato starch crystals perfectly clean the surface of the intestines and significantly improve the health of the digestive tract, as well as the immune system.

So what benefits do potatoes offer dogs? They particularly contain a large amount of minerals such as magnesium, potassium, iron, zinc and calcium. They are also rich in vitamin C, A, B and E. Thanks to their carbohydrate content, they are also a great source of energy.

Another advantage is that they don't cause allergies unlike grains, which dogs can't even digest. These allergies result in digestive and skin problems. Potatoes are also less caloric than grains. 

Some dog food contains up to 50% of potatoes, particularly for dogs with higher energy demands. Conversely, dogs with diabetes would not be able to eat so many potatoes. 

Do you have any experience with potatoes? Have you noticed a difference between potatoes and grains in your dog's diet?
