I'd like to add my two cents...if a pure bred dog is well bred, it won't have the problems mentioned. Good breeders won't breed a dog if it has allergies, or if it has a temperment problem, or if it has some kind of gentic problem which can be tested for.
There's also no such thing as a "cheap" dog. You can get a mixed breed puppy from the pound, and still have it come down with expensive health problems, even if it looks like a Heinz 57.
Just like with human babies, there is no guarentee in dogs.
Also, in regards to longevity, it depends on the specific breed, and the pedigree of the dog in question- at least for pure bred dogs. I can tell you that its rare for a Great Dane to live past 10 years, but if a keeshond went to the bridge at 10, I'd say they died young.
Getting a dog takes a great deal of love and dedication, whether you're going for a purebred or for a mixed breed. There's no such thing as a free puppy...
