I will say unsoundness, in the GSD, is probably the leading problem to choices in Police work. If you are paying $15-20 THOUSAND a dog, you should expect to get at least 5 years from that animal. Not so true with the GSD, especially the American bred lines. I do see European bred GSDs being used, obvious with the longer, fluffy hair, standard sizes for the breed, not monster sized. Athletic dogs, of 70-90 pounds, that can DO THINGS.
Our local County Sheriff Dept. keeps a police dog, who gets a LOT of use, mentioned in the local paper as assisting in many incidents around here. He sniffs drugs, tracks, and will find, hold a suspect being pursued on foot. Dogs visit the local schools, very personable animals with the kids. We have always had a GSD “on staff” for the County, gone thru a number of them over the years. Not sure where they shop, dogs last about 5-6 years, nice specimens. Again, they do get a LOT of use, so those working times could be stressing on joints, for a shorter work life. Prices I mentioned were what is quoted in the paper, when they go shopping for a replacement dog. Retired dogs usually go live with the handler as his “house dog” until they die.
As a long time GSD fan, we raised them when I was a kid, they just have not ever proven to be a long-lived dog for us. They were seriously aged at 7yrs and up. Maybe they wore themselves out with constant busy-ness around the place, because they ALWAYS were doing things. We had to hunt far and wide, to find animals without issues, no history of issues, and THEN the show breeding made them into giant lap-dog wannabees! Not guardians, beyond barking some at new arrivals. And if you didn’t keep them BUSY they got into trouble or invented problems with their intelligence. I gave up on the breed quite a while ago, though I still love the look. The Malinois, Tervuran (sp?) just never were as appealing to me with smaller size, different minds. After hearing about them from friends, I don’t want one.
We ended up changing breeds, and I like our choice. They are as nice as the old-type GSDs we had as kids and make me feel the “home place” is covered when I leave. Lucky for me, they have not been nearly “GSD creative” in causing me problems either.
