It's also lab-proven and vet-approved, ensuring a high standard of effectiveness similar to conventional products. This shampoo is suitable for both dogs and cats that are over four months old, which makes it versatile for multi-pet households.

The soothing properties of the essential oils help relieve itchy skin, adding a skin and coat benefit, which is a big plus for pets with sensitive skin.
