Hi Everyone! I'm a first time Puppy Mommy and this site has truly been a blessing to me! My puppy is 13 weeks old and I love his coloring, but I realize that will change...but can anyone tell me at what age that starts to happen and how long until it's his final coloring? I did meet the parents at the breeders, but they were both different coloring. I've seen so many variations in coloring that I'm so confused. Thanks!
