I am always a nervous nellie when it comes to my three dogs so please bear with me. I was out in the back with my dogs when Thumper came around the pool limping on her right front leg - it seemed to be her foot. There is no swelling, and it seemed to get better after I restricted her exercise for a few days. Low and behold, she yelped today when my rottie accidently stepped on her foot. I've examined her paw, and can't find a thing. Any suggestions as to what might be wrong? - Cathy
