Max is adorable. I have a GSD also, she turned 3 yrs end of December.
Unfortunately, as you may have noticed, this forum doesn't seem to be active as it was back when you were first here. Most of the original posters left many years ago and this site is like the Marie Celeste. In place of good posters and topics, there seems to be an influx of spam bots, that have taken over this site.
I don't know if this forum will ever get back to its original purpose. I hope it will.
