Gail, I think the page has been taken down. I was doing a search the other day, looking for any updated info, and couldn't find it.
I hate referencing something and being unable to provide the source. I'm sure many here are familiar with the study as the link has been posted here in the past.
Just going by memory, the study was done around 2001. I believe there were over 2,000 dogs included in the study......probably about 15 different breeds plus a group of mixed breeds. The highest incidence of liver shunt (percentage wise) was with the Havanese, at a little over 4% affected. The Yorkshire Terrier came in at over 3%. Other pure breeds had smaller percentages affected. The mixed breed group had a very low percentage...under 1/10 of a percent. It wasn't spelled out what mixes the mixed breeds were, so I don't know if they were cross bred from 2 pure breeds, a Heinz 57 mix or some combination of both. |
