I don't know if you can tell in this picture or not what Rosie looked like as a pup. It was a long time ago and from my cell phone. I am attaching one of what she looks like now as well.
Her face had a lot of the silver in it as well. But now it has more tan. But her body has a lot of silver where it had more black as a pup. Your furbaby reminds me a lot of what she looked like.
Maybe even a little more silver in him.
