Calmed and his coat returned.
Mental health affects the physical in dogs too.
My Shar Pei cross suffers from an on-going skin condition, linked to this he finds it difficult to rest and relax and a cycle of behaviour results. After the first day of adding the supplement to his feed I saw a significant improvement with calmer behaviour, on going it has had an accumulative effect, enabling more consistent calm behaviour and an improved ability to learn. His skin condition has improved and become more stable.
