Health Survey Series
Scottish Terrier Health Survey of 1995
and its place in controlling Scottie health problems
By Linda L. Orsborn
We are fortunate to have a hardy breed of dog, but we do
have health concerns that could and should be considered as we
share our lives with our dogs and some of us choose to be
breeders.
In 1995 the STCA compiled its first comprehensive health
survey. Along with a list of genetic problems seen in the
Scottish Terrier is a “guesstimate of frequency rate”. The
“guesstimate of frequency” indicates the percentage of
Scotties that may carry this particular trait. It does not
indicate the number of affected dogs. The Hardy-Weinburg rule
states there will be approximately 1% affected for every 18%
of carriers. Usually the Hardy-Weinberg rule is applied to
single gene traits, but for this health survey Dr. George A.
Padgett, DVM applied this theory to all guesstimates.
Below is the chart of diseases known to exist in the
Scottish Terrier.
Hopefully, the information in this survey will help you to
better manage the health of your Scottie. Consider researching
some of the diseases listed above and share this survey
information with your veterinarian.
