Aussie Health Links
Here's one link I thought you might be interested in on Aussie health.
Health concerns and your new Aussie.
While in general Aussies are a very hardy breed there are a couple of health issues that are Aussie specific and we would like to do our part to make all future Aussie owners aware of them.
NEVER PRESCRIBE IVERMECTIN TO
ANY AUSTRALIAN SHEPHERD
Pretty much the first paragraph says it all. The health problems created by this combination are often hidden until you fall in love and are many thousands of dollars into the health care of a "pretty" yet unhealthy dog.
While Aussies may be best known for their unusual
merle coloring, the incomplete dominant gene which produces the pattern is
semi-lethal. When a dog inherits two alleles for merling, which can happen only
when a merle is bred to a merle, the resulting puppies
A merle to merle cross will require that, on
average 25% of the puppies be euthanized at birth, as
gene is connected with disorders of eyes, ears and other internal organs. The
exact cause is unknown, but one current theory suggests
that the lack of melatonin interferes with the correct development of organs
situated directly beneath the under pigmented areas. Each
merling allele inhibits more pigmentation from the solid coat pattern.
Therefore, a dog which has two alleles for merling may completely
lack pigmentation, especially around the head. Because of the correlated
defects, "excessive white" is a disqualifying fault according
to the ASCA Breed Standard.
