|teacup toy aussies - estimated to be 10" or under,
"micro" toys -estimated 8- 9" - 6lbs & under..
we have set these terms/sizes ourselves trying to
distinquish between the sizes.. there is a major "volumetric" difference
between the mature size/weight of a 13" TOY, and a 9" micro toy.
thier ears may or may not be "perky" but will send ear
glue to glue/set them down.. the smaller ears just tend to not have
enough fold to go/stay over on their own- it is a fine line between
perky ears & "spaniel" ears..
They maintain the smarts and temperment of the mini-toy
aussie, we breed for not hyper or yippy They
don't have the health issues of other small breeds comparable in size,
or the grooming requirements..
PLEASE NOTE- we have selectively bred DOWN in size. these are not
"runts" or premature puppies. They are vet checked for health.
Science has now identified "growth limiation" genes in dogs,
why a chihauha is smaller than a great dane. multiple genes exist
in smaller breeds and the number or type of limitation genes determines
the dogs final size. In the aussies, so many breeds went into the
aussie that I think several different size limiting genes exist.
and if a puppy gets "all of them" they end up being smaller.. we
have puppies that are 2 lbs at 9wks that mature only 4lbs.. they just
don't grow anymore .. and rarely we get one that didnt' get any of the
"stop growing" genes and matures much larger than their parents.
we can tell these at 4-6wks.. the puppy either slows/stops growing or
just accelerates growth.
our goal with the teacup/toy aussies is to keep the intelligence,
loyalty and looks of the aussie - minus the herding - in a smaller house
sized dog that doesn't have the grooming requirements, health and
yapping issues of most small toy breeds.
