there is nothing wrong with merles in fact they have made great workers and should not be avoided i have bred 2 litters of them and every pup turned out to be dead on in the feild
There's no reason why a merle can't be as good a dog as any other but there are risks involved and why take them? Because they look pretty? If you've got a fantastic dog that's merle then by all means breed but be aware of the potential problems. To go out and look for a merle makes no sense to me.
BTW Clover I'm aware it's not a colour...you know what I meant.
Sorry Jammo1, I know you didn't ask that
