As of a few days ago Brinkley is running alone full throttle for sheer joy of running. My other tervs did this but because they were adopted at about 2-3 years I never saw this develop. I was assuming she was just different about her lesser need to run. She looks more mature each day. From 3 weeks ago her puppy look gave way to young adult now. So elegant and angelic. She has chewed up my mattress and every pillow that I forget to move out of reach. Also in past week she comes into my bedroom twice and cried. When I got up she led me to her other sleeping area near kitchen where teapot was whistling that I couldnt hear. Could still be a coincidence or could be her warning me of the noise/something wrong. Time will tell but interesting in the meantime. …… marc
