we had a little snow the other night, and the building manager put down alot of salt on the walkway and the steps. it seems that it gets caught in sophies feet and she limps untill i rub her feet and it falls out. it has gotten to the point where she waits for me and lets me do it without horsing around. for her, that in itself is unusual. do i need to buy her little boots? i have always thought that doggie clothes were the reasons they bite people. do any of you have this problem with the salt? solutions? anyone?
