Hi, everyone. I need some advice from you guys. I'm waiting for my puppy (black headed tri)which will take 2 more weeks. I visited the breeder and saw the puppy today. I noticed he's got bluish-grey eye color. There was a one more tri-color puppy w/ same eye coloring. Though, other red and white puppies had dark brown eyes. Breeder says they will just turn dark brown when he gets older. Is that something common for tricolor cogis to have a bluish-grey tone eye color when they are puppies?
