I also wonder what the #1 cause of death is in Sweden; if it is the same as in North America with all cancer being #1? |
Hi Gail,
Here are the data for Yorkies from Table 1:
Table 1: Breed, proportion (derived from Cox proportional hazards regression without independent variables) of bitches that developed disease, rank, and numbers of cases in different breeds that by the age of 10 years had developed pyometra (P), mammary tumours (MTs), and either or both of pyometra or MTs.
Breed: Yorkshire Terrier
Pyometra %, (number): 21% (n=157)
Mammary Tumors %, (number): 25% (n=176)
Pyometra or Mammary Tumors %, (number): 39% (n=301)
Total female Yorkshire Terriers in study: 1959
The percentages indicated are quite high in Yorkshire Terriers. I will email you a copy of the whole study so you can read it in greater detail.
