It's interesting. Ellie "corn cobs" her front legs and back hips, has bitten all the hair off the base of her tail (underneath), and scratches mercilessly at her shoulders, but is not bothered by either her feet or her ears. Recently she has begun scratching at her mouth and she is beginning to have dark staining in her wrinkly jowls. Everything the yard is growing like mad right now here in Northern California and she loves to walk through the garden, so I am thinking we will experiment with fencing off where she can romp in the yard and see if that helps quiet her itches. She often cries while scratching, but she is very, very vocal dog to begin with, so I am not sure how much discomfort that indicates.
