I have a black 2 1/2 year old Labrador Retriever (neutered at 2) who is itchy and has some noticeable dandruff. I am sure you see more on him due to is color. He eats raw, gets Colostrum, hemp oil, Vit. C, Krill oil and a combination Enzyme and Probiotic. My holistic vet has suggested dog bloom vm supreme. Has anybody had good luck with this product?
