My parents had a yellow lab that I would take to the river to swim - so it's not a problem for me to have your dog engage in activities sans leash with your approval. I have experience walking more than one dog at a time. I live equidistant to two dog parks; Walter Reed and Shirlington. A little further away is the Glencarlyn Park, which I have taken dogs there too. I am extremely active, and would absolutely love to take your dog(s) with me. The W & OD trail is across the street from me, and there is a trail that runs behind my building. I was born in the year of the dog from the Chinese zodiac, which naturally means that I am a part of their tribe.
