The digestive tract of the dog is ideal for digesting protein, unlike humans, a dog’s gut has a very acidic pH, making it equipped to resist pathogenic bacteria but not to digest grains.
By feeding your dog processed food, you may be increasing their risk of bloat. Most commercial foods are highly processed and when your dog eats kibble with grain, it turns into porridge. The stomach doesn’t need to work very hard to digest it, and over time the stomach wall muscles become weak.
A weak stomach is much more prone to dilation and gas build-up which happens especially with carbohydrate rich foods. Therefore grain-based foods are one of the main sources of stomach bloat in dogs.
