I am fairly new to the cavaliers. I'v breed poodles and Yorkies and color wasn't an issue except with poddles being bred with same color.. From what I'v read you only breed to make the cavaliers better and if dogs have certain faults they should not be bred. Are markings also considered reasons? If so if one is in the same litter your dog could produce some mismarked puppies also (even if she got perfect markings)..does this mean she shouldn't be bred? I know the bite is a major fault, am I right in that? Do you ever even with the best looking parents and grandparent s have PERFECT litters. I'd just like some clarifaction on this please. I am wanting to show and breed..Thanks all
