What more can I do for my dog?

It’s important to support your dog’s microbiome with good food  - a healthy, species appropriate diet that is raw and easy to digest is best. Canine Nutritionist, Narelle Cooke, says “the diet we feed has a direct effect on the composition and diversity of our dogs’ microbiome and may be the single most important factor in preventing illness and maintaining health.”.
