  1. Since these three cancers are considered to be nearly universally fatal diseases, an assumption was made that these dogs are deceased.  It is acknowledged that this is an inherently flawed assumption because some of these dogs may still have been alive at the time they were entered into the survey.  Therefore these percentages are clearly inexact, but are included here just as a very rough comparison to 1998 data.  The percentages in this column and in the “Change in Prevalence” column would be decreased when dogs die from these diseases after the time their data were entered.
