Nothing wrong with Guido-especially that age. They have tons of injury and just love people. She's lucky to live where she gets both. See too many springers that the owners have tried to turn into house dogs. I just came back from a run on the beach with Pepper who is now 14 1/2 years old. She definetely is slowing down and has a spinal issue that causes her real legs to fail her often when she tries to jump. And, as with most springers, at her age she is almost 100% deaf. But she's had a great life and we (me) keep running her on the beach, parks, and get her in the ocean as much as possible.
Enjoy Guido-she sounds wonderful.
