help, maggie our 2 yr old golden licks her paws until they are raw. i have tried everything the vet has suggested, such as, changed her food to WELLNESS NATURAL, spray bitter apple on them, she had steroids for 2 wks, i wipe them when we come in from our walk, i apply four paws paw guard nightly, and use a medicated shampoo on her paws, no relief. i have notices lately that her nails seem to have dried blood on them at the nail bed. she doesnt seem to be in pain, but her paws are so raw. i am so concerned and upset. please help her. maggiemay
