Please do NOT breed your DOG!!
Not when their are millions of homeless dogs and cats dying each year b/c of back yard breeders.
Breeding should only be done by people who love the breed and can guarentee the health and longevity of the breed.

Your dog will be happier and HEALTHIER if it spayed or neutered.
The risk of testicular and breast cancers is dramatically reduced if the dog is altered.
Unless you are going to be a responsible dedicated breeder Do not advocate having puppies until you have educated yourself on the facts.
