In the past I had a Boxer for many years, high energy but nothing like the GSP. Just wondering if anyone has any specific toys they have found to be good, or perhaps even a workout regimen. I am considering some options, trying to be creative, to create intellectually stimulating situations in my yard. But also plan to take her hiking, and locate some wide space to run her. Before we get to hiking and space I plan to work with a trainer to ensure we have obedience well-covered.
