have u been walking her on salty roads or sidewalks?? the salt use to bother Max to the point he was licking his paws so much they were bleeding... now we wont let him on the sidewalks unless he was his botties on or if we wash his paws afterwards... try the booties thing... but wash his paws right now & but some medicated cream on them & tape a sock to his leg (put the tape on the sock & not his fur)
