-
Dogs in this survey were a minimum of 5 years old, and the selection was further weighted toward older dogs by requesting that owners entering multiple dogs select their five dogs with the earliest birth dates.
-
Dogs entered into this survey could be any age, and therefore many may not have yet reached ages for which a cancer diagnosis is most likely.
