hi i walk my dog often, using an electric collar, so she can run after squirrels and things. her paws get really dirty, even after a quick walk. when we come in i have her lay down right away, i then spray one paw at a time with a spray bottle of water and some vinegar. i then wipe the paw clean with a towel, and then scrape under the nail. i then do the other paws. after the towel is so filled with dirt its nasty! im thinking there are many out there that dont do this and that dirt gets into their home. does anyone else do this? just wiping with a dry towel and not using water wont get 1/4th the dirt as with water. someone?
