Rita's mom, I understand about walking in town feeling safer, but remember blue dog's breed. Our herders were born to protect and yours has the strength to back it up if she's anything like my Texas Heeler (Heeler/Aussie) was. I was always glad Sasha liked me! I wouldn't have wanted to be her enemy. I tried the intense walking for 60 second intervals tonight. It's not hard because it's so temporary. Because it was dark out, I also did some marching. I don't want my neighbors to think I've lost it totally. Funny thing, I left tired from planting flowers and mowing all day and came back more invigorated. I did get a rest period. My teen age friend had another ball game tonight. It was rained out, but they got in enough innings for another win.
