The combination of kombucha tea and essential oils is in itself very hydrating and antibacterial. Each Probiotic Pet Solution works to moisturize and deodorize, leaving our pet's skin and fur soft and freshly scented. Our Probiotic Pet Solution comes in FIVE scents. They are made with different essential oil blends. The essential oils we use all have properties to promote healthy skin and fur. For more serious skin conditions like severe irritation and rashes or severely dry skin, we recommend Charming Chester or Dashing Dewey as they promote skin healing and soothes inflammation. For any other skin types, normal to mild skin conditions, you can go for any of the five scents. Here's a guide on the type of scent for each: Charming Chester - sweet woody, Dashing Dewey - musky earthy, Pampered Peanut - fresh citrusy, Magnificent Mia - sweet floral, Adorable Annie - herbal calming.
