I found these worked well to keep my dogs from chewing. Bitter Apple deters your dog from chewing or licking his/her fur, hair, and hot spots. (paid $9.99). Bottle is 1/3 full. Bitter Yuck deters dogs, cats, and horses from chewing on furniture, drapes, wood, stalls, and themselves. (paid $12.99) Bottle is almost full. Both for $5. Pet-friendly home near Jubilee Hospital.
