I had a GSD who was a relative of ‘Manhattan’. Would have been a top quality show dog except for having long hair. Dumb as a box of rocks but sweet.
Our GSD is a little over 10 and is as fast and smart as she was when she arrived about 8 years ago.
Other than a little gray around the muzzle, it’s hard to tell she is a senior dog.
The vet always says great things about her health and overall condition.
Looks good on camera too:
