While this is not a pleasant subject, we feel that it is one that needs to be addressed.
Cancer is the leading cause of death in dogs.
This is why we recommend the spaying or neutering of all dogs not intended for breeding purposes. Some breeds seem to be more susceptible to a certain forms of cancer. If you are considering purchasing a puppy please discuss this issue with the breeders that you contact. From many discussions with people that have been through it, and our own limited experience, we know that when it happens it can be heartbreaking. The decisions are tough and very personal.
