5 weeks old border collie puppy by Hanabanana (CC BY-SA 3.0) Generally, your pup’s eyes are fully open when it’s around 14-21 days. And since most dogs are born with blue eyes (due to a lack of melanin) or gray eyes (though this happens rarely), it’s quite normal for dog parents not to pay close attention to their dog’s eye color.

First and foremost, you should never ever breed two merle Border Collies together. Breeding merle-to-merle will inevitably cause deafness as well as vision problems in future generations, because of genetic conflict. Breeding merle-to-merle Border Collies is only done by irresponsible and ignorant puppy farmers.
This applies to all types of merle (blue, red or sable). The merle gene that produces this colouration is technically defective, and as a result, there are concerns that a dog with a merle coat may be more prone to certain health issues. Including a range of eye problems, potential hearing problems and possibly other health complications.
The patches vary in terms of shape, size, and color. In dogs with the merle-patterned coats the gene responsible for the coat pattern also affects the eyes, nose, and paw pads. In terms of eyes, merle dogs can have differently colored eyes (odd-eyed), unusually dark eyes or blue-colored eyes. As for the nose and paw pads, they can be mottled
When two merle-patterned dogs are bred together, each puppy in the litter has a 25% chance of inheriting that gene from both parents. The resulting offspring is referred to as a double, or homozygous merle. Double merles often have a predominantly white coat. Keep in mind though, that just because a dog has a white coat, doesn't necessarily
That said, Collie Whips typically take the colors of Border Collies and the physique of Whippets. Whollies are considered small-sized dogs, weighing an average of 25 to 55 pounds and standing at 18 to 22 inches high. They have an athletic build, an average of the Border Collie’s short, stockier body, and the Whippet’s tall, leaner physique.
