I have a large German Shepherd, that was eating his backside and legs off. This has been going on for two years, I have to give him something to sleep atnight so we both could sleep. To wake up to hair all over the floor that he has pulled out. On Nov.17th I started with the plain yorgurt (1/4cup),1 Acidophilus, 2 8000 I.U.Vit.A tablets twice a day. Was still using his Anthisamine at night to get him to sleep. Last night he didn't have to have it. He sleeps all night, can lay in the livingroom floor for hours and not scratch. His skin looks good hair is growing back,still has some minor problems but it is 75% better. For less than ten dollars and two weeks I have my dog back. I gave this to my small dog and her shedding has stopped, no more hair on my sofas.
