when we're out on walks I don't notice it, but walking around the house I do...You're right, she could be a little lazy in the rear...I know she has always, on occasion, drug her toenails when walking...but she runs, plays and jumps quite well...too well sometimes. She's not getting as much walking these days...too hot for long walks...she and gracie are getting about 1/2 a mile am and pm...except like tonight when we had class, Lucky got shortchanged on the walking.
