It depends on the breed. Often it would be about 245. It's very unlikely that a dog would be that old. Between 4 and 5 depending on the breed.
It depends,what breed and personality does it have? Is it bred to be a fighting or hunting dog?
Yes. Do not breed females after 7yrs for most breeds except English bulldogs, which should be retired by 6yrs.Males, if sound, can breed till 8 or 9yrs.
1.5-2.5yrs, no earlier.

It depends on the breed, but most live to be at least 10(70 dog years)
