Our Yorkshire terriers comes from top imported European bloodlines. All of them are non Merle dogs. Some of our dogs have the blue diamond gene (Blue eye colour). Some of them have the brindle gene (coat colour), but all of them have exotic colours in their bloodlines (coat colour).
Between breeding German Shepherds and Belgian Malinois. Our yorkies grow up to be pretty alert and rugged. To fit into the pack they need to be as tough as nails, because we have an average weight difference of 30+ kilograms between yorkies and our other breeds.
