Most of the dogs are in the 6-8 year old range. From what I see in the previous photos and videos there are a lot of purebreds.
Here's first one being saved: https://www.facebook.com/gsroc.org/photos/a.109191994514.116192.105289464514/10154141364839515/?type=3&theater
Prayers for the dogs and money for the rescue are needed.

I’m not young and active enough for one of these animals but for an active owner with a good understanding of these fine dogs, they are great. Properly trained, they are good with active kids and very protective. A smart dog.
At my age, a French BG is perfect. Smart as any dog but more laid back. Must have exercise but nothing near a German Shepard or similar.
One of the articles references the dogs being possibly mixed with chow chow due to black spots, but purebred GSD can have black spots on their tongue.
