First I would like to say that I am not a Vet. Please take this information and study it first before using any info on your dogs or puppies. You can google.com or yahoo.com or even ask your Vet for more info. But please note some Vets will advise you not to go this way. I think because this will take money from them but will safe you money and still have a healthy and happy dog/puppy. I am a breeder that uses like many breeders do and have no problems with using the following info.
