Not a time I would have picked either. My two were 18 months when I got them and were called Greebo and Merlin. I wanted a little tom cat called Frankie (Greebo isn't a nice name) so I decided to change his name (chap in my avatar) but Merlin is still Merlin but she is called Princess Merlin (also known as Princess Stupid or Princess Slasher).
I like GSDs - both of dogs have been half GSD. Thinking about it now, they were both cat chasers. I can honestly say that they would find Merlin a challenge, she has a feisty nature.
