The only breed specific cancer I can really think of is Bone Cancer and it tends to happen in Larger Breed dogs, especially greyhounds. I also know a deerhound breeder who knows a wolfhound breeder that bred her dogs at age 2-3, the female got Bone Cancer at age 5 and when all of the puppies from that litter turned 5 they got it as well.
Again although common in large breeds/greyhounds bone cancer isn't limited to those breeds. I've known a poodle who had it, a shepherd, a chow cross, a labrador, several greyhounds.
I've seen lymphoma in an Australian Shepherd, English Mastiff, Pit Bull, English Setter, Springer Spaniel, Boxer.
I've seen nasal cancer in a cat, my own mutt dog, a Shar Pei, and a toy poodle.
I've seen mast cell tumors in a couple of Boxers and lots of labs.
I don't really think, unless it is in a dog's family tree that you can really pin point specific cancer. Obviously if the dog comes from dogs that have had cancer, it is more likely to get that cancer if it is in the gene pool.
