Difference between GSD lines - Page 2

This is a mix in of several of the posts I have been reading, First How do I tell on the pedigree where my dogs originate. I have Flex vom blauen Modeneser on one side, Quando Arminius wit another and several of the Weineru , ulla vom fleisherhem, V eros witzmannsberg and so on. Also, I get a variety of colors. But ALWAYS solid blacks when I mate solid blacks, and I mean SOLID. Not a hair of any other color no where on my dogs. I have gotten Blues when breeding the 2 solid blacks, and I have gotten Sable with a black mated with a black and tan. I have 7 Solid black pups now, some plush coat, some regular coat. They are just 3 weeks old and I have been feeding them canned puppy food for about 4 days now. Their mother is happy to give up Her Time With Them. She is my worst mother dog, but she produces Beautiful Pups. Anyone there able and willing to help me learn the origins of the pedigree. Any help will be GREATLY appreciated.

kitkat: Flex is East German DDR the rest are or come from West German Showlines.

Kat, this is a data base. Put your dogs names in the data base and see what comes up. If nothing then do a google search. Your question is also off topic and needs its own heading. Kyle
