There are two basic
patterns of the Australian Shepherd - Merle & Solid. If you
breed Merle to Merle, you need to be aware of the Lethal White Merle
gene. Simply put - Lethal White is the presence of TWO merle
genes, one obtained from each parent.
If there is ONE merle area on the dog, no matter what size it is, the dog is a Merle. Breeding merle to merle will present you with the possibility of having 25% of your litter carrying the Lethal Merle gene. These pups will be (or soon become) blind and/or deaf. To be safe and not have to cull any pups - breed Merle to Solid To be considered sound: Each ear must be covered with color other than white. No white on the body behind the shoulder. No white up the stifle on the hind leg into the body. |
