Sprocket takes a vit B-complex daily, his diet is a combo of home cooked and natures balance. I am a believer in vitamin B for both humans and animals. For humans (me) it helps strengthen my hair, skin texture, keeps me from bruising and being a redhead I have horrid tender skin. I asked the Vet about the vit B for Sprocket, she said "can't hurt, one a day and any extra he doesn't need, he'll pee it out". Vit B is water soluble, even though Sprockets are liver flavored, I buy both his and mine at GNC.
I have been told that with the holistic approach you can change the skin "flavor" so the fleas don't like your dog with vit B, though I haven't tried this.
