Nutrition and your dog's food plays a large role in skin health. For example protein and amino acids are important for hair growth and omega-3 and omega-6 fatty acids are key for coat quality and reducing water loss through the skin.
Dogs with ingredient sensitivities or food allergies may be at risk for developing a pyoderma after eating something that causes a reaction. If your veterinarian suspects a food allergy, they will need to treat the skin infection and then they may recommend feeding your dog a therapeutic food to see if the skin problem abates.
If your dog doesn't have food allergies but has pyoderma secondary to other health concerns, like a hormonal disorder, then it might be a good idea to feed your dog a food that's specially formulated for dogs with sensitive skin. It's crucial to talk to your veterinarian about the ideal food for your dog because it is important to make sure your dog receives the best nutrition possible.
Pyoderma is a pain, but with a little knowledge and care, it can be resolved. If your dog develops pyoderma, especially more than once, understand that you're dealing with an underlying issue that needs resolution. If you notice any of the signs of the infection, call your veterinarian so that you can work together to get your pup back to feeling like their best self.
