Jerob B-Calm is the gentle way to calm and soothe a show, breeding, travel-shy or vet-bound animal. The natural amino acids and herbs in B-Calm are the safe, sure way to calm without unwanted side-effects. B-CALM contains natural L- Tryptophane, which has been used successfully with animals for more than for half a century. B-CALM DOES NOT CHANGE THE NATURAL DISPOSITION OF THE ANIMAL. If you are working with a BAD disposition, don't count on B-Calm to change it. But if your lovely little critter gets upset going to a show or the vet, a little B-Calm can help. Start a couple of days before the show, and continue through the trip home and you'll be amazed.
