@the evil twin
Wow, 13. I remember when you got him. Time flies. My last GSD was 35 years ago, and as I only work 9 days a month now, I've got the time and effort to put into him. On my 'break' it still takes me a day to whip him back into my gear, then we're good to go. lol.
We've also got a 11yo bitza, who's now got a new lease on life. Cyclone's bigger than him already, but the old one still gives him a run for his money, and they rough and tumble all the time. Got him from a breeder in South Oz and more than happy.
Take care and will try and catch up sooner rather than later.
