I think it all depends on you. I don't think anyone should have the right to judge if get a dog or if you don't. We don't personally know you (alteast most of us don't, I'm assuming) so we really don't know the circumstances. (that's not to say you are or are not making the right choice in getting another dog...I just feel it's up to you to tell if it's the right time)

After my old dog, Rufus died I didn't even think of a new dog until one day I felt it was ok. It probably wasn't more then 3 months either. I had the perfect dog in mind. I want a YOUNG pup, a border collie probably. However, I went with someone completely different and do not regret him one bit. He was 6 months, and I really wanted a pup, but I love him to pieces so it doesn't matter. I don't know that GSD are the best for agility if that's what you're looking for..?? But I don't really know much about it.

All I'm trying to say is, think hard about what is best for your life style..even if it's not EXACTLY what you wanted. It will be more worth it that way. And maybe sometime down the road you will be able to get that dream dog of yours..or maybe the one you get will end up being the dream dog (even if it'snot a GSD)

Good luck with you decision. Be sure to let us know.
