were can i get melatonin? i am going to try it on my bonnie she still has a lot of hair missing on her sides. the vet. is stumped he says its not mange but doesn't know what it can be, bonnie is in good shape. she started loosing the hair after getting spayed.I was giving her Biotin in her food and vitacaps twice a day and nothing. Bonnie is a 5 yr. old flashy brindle and my male Clyde a fawn is ok no hair missing at all. I been feeding them Pro Plan since they were puppies. I realy don't want to start taking her to different vets as that takes a toll on her and also on me($$) any help would be greatly appreciated. thanks Ray
