My chihuahua had a lot of skin problems caused by food allergy. Once i had found the cause of his allergy my vet advised me to use dermoscent essentail spot on. I have used it already a month and now give him one pipette every 2 weeks. It is just great! He smells beter, loss of hair is a lot less then before, and his skin is so much beter.....I recommend it to every dog owner.......
