Animal Care Needed - Now Hiring

Dexter is a 2-year-old German Shepherd. Dude loves playing catch and being outside. I usually keep my patio door open so he can go people watch when im gone for short times or busy inside. Hes a very playful and sweet boy but a little anxious if overwhelmed. knows commands from sit+ stay to roll over and speak. I want to find a place he can be outside quite a bit, he would stay out there all day if id let him. we usually take 3 30-45 min walks a day with catch and commands worked in. want to try to find a place that can keep him relatively active like he is at home.
