Ya well, like you said tumors just happen, no matter the dog, it happened to one of my godfather's dog, and she was the healthiest of the two dogs he had, they were actually expecting their other dog to pass away far before her (and it's been about 2 years and the other one is still fine, go figure.. She's blind and deaf, but still fine...).

And yes well, that's just like with humans... The first tumors don't appear and offenly you don't even notice it, until they get bigger or in a place that start hurting...
