Whilst my Indie, a two and a half year old Cobberdog, still scratches and bites at various parts of her body, there is no doubt that she is much improved after taking these drops for several months.
Then I ran out and the tearing herself apart came back in force, so now I make sure I always have some on hand as after an initial 2 months at twice a day.
I only need to give them to her when she's having an attack (as we call it).
