Not only for humans but also for animals, the digestive system is a vital part of the body. And it regulates the whole food in the body. However, the dogs are as curious as small kids and always put everything in their mouths. Thus, vomiting and diarrhoea are signs of toxic things in the digestive system. Therefore, for digestive issues, you need to choose a complete nutritional food specially designed for your dog. Moreover, it needs to be rich in digestible ingredients, essential nutrients, and EPA or DHA, which helps the dog to have a healthy digestive system.
