Boosting the immune system is one of the most effective ways to fight against disease in dogs. Just like humans, dogs can build their immunity through various aspects such as a healthy diet, routine exercise and good environmental conditions.
Among these, the most important thing that plays an essential role in dogs’ health is what they eat every day.
Typical commercial food or kibble is far enough to meet your dog’s needs. Fruits and vegetables have amazing nutritional benefits for dogs when you choose them wisely.
So, what foods can boost the immune system of your dog?
