Not quite right there. Size is a factor in that many of the large breeds do have a shorter life expectancy but there are plenty of breeds that are of vastly differing sizes that have the same average life span. Chalk that up to breed type/genetic tendancies, typical life styles. Granted many of the smaller breeds are among the longest lived, but not necessarily all.Jack wrote:just as smaller dogs live longer than larger dogs.
Oh, and your average life span of the great Heinz 57 is 13 yrs.
I found the following on good old Wiki and it jives with what I know about their lifespans, so seems about right to me...
