I am used to taking three of my own large pups out for runs and hikes at home, and know how to tire them out! I have pet sat for numerous friends back home in Virginia, including a two week stay at a friends house with eight handicapped german pointers. Two of them were blind, one deaf, and the others had some minor behavioral issues. They had a two hour walk every morning, and none of them went on a leash. I had a great time with them, and never felt overwhelmed once! Looking forward to caring for your pup(s)! I currently live in the White Mountains of New Hampshire, and always have free time on weekends, and at the moment, I am also mostly free during the week.
