Congratulations!! We want lots of puppy pictures! As far as names?? I like strong German names. Our first Rottweiler was Bruno, and our Doberman was named Fritz. My other male Rottweilers were named Baxter, Teddy, Bogie, Lazlo. Mauser sounds kind of like "Mouser" to me...LOL You have to think of when you need to call them in a loud voice. Let us know when he arrives!
