I have a full DDR female pup as of now, and she's great! She's a ton of fun to live with. She's confident, energetic, but also has a good ability to calm down in the house for a pup!). She's a lot more mouthy than my other GSD ever was. She is very clear headed as well. As far as health goes, you need to find out what exactly your breeder is doing as far as health tests. There can be problems with health in any bloodline. Find out what it is your breeder is producing as far as working drives. The breeder I got Tinah (Tina) from has certain breedings and even particular pups from litters that need to go to working homes, and several others that do completely fine in an active family setting.
<< Melinda at Vom Gildaf is great. She currently has a DDR litter on the ground out of Kantor and Mako. Tinah is out of Kantor and Edge. I met Melinda's dogs, and they are very fun, outgoing, and have awesome temperaments.
