The products are not formulated to be used on puppies. Further, the usage of products on puppies should be reduced to the bare minimum, since they are more sensitive. If one wants to use BellyDog products on a puppy, please do a patch test before applying it all over the dog. This is a general recommendation for every dog product and brand. (The only products that I would recommend for puppies are: No stress (since it's not on the skin), Paw cream and Golden Oat.)
