I was having a hard time dealing with my dog allergies and dandruff this winter. At first I was only using Proseb shampoo prescribed by my vet but after weeks the dandruff was not getting any better...So I was looking for something to boost the treatment and I was so glad to give this product a try. The dandruff disappeared in two days! I was very impressed! The dandruff is now finally gone and he is not stinky anymore, I hope this helps someone looking for something extra to treat a stubborn dandruff. :)
