Not sure if this has been posted yet but just in case...
Wow!!! Thank you for posting. That description of the German Shorthaired Pointer describes Rocky to the tee!! Hyper , Trainability, need for exercise, room to run and purposeful jobs that GSPs love to do. Great swimmers with web paws and water repellant coat. Believe me after living 13 years with Chese/lab who had joint, arthritic problems, found it very refreshing to hear the GSP doesnot have those problems. Yes Rocky still at 7 yrs 11months old can leap high in the air to catch a tennis ball. Unbelievable. Yes I do have a GSP adopted from the Rescue who is true to the breed description who I just love so much!!!
