I was bathing and grooming Logan this weekend and saw a few spots that are a bit concerning. Maybe not enough to run to the vet but concerning enough to post these pictures. The first picture is of his tummy near his penis. The little black spots are what I am concerned about. Could they be like blackheads in humans? The second photo shows his rear hocks. The area shows that hair is missing. The area seems to have dry flaky skin. It is identical on both sides of his rear legs. Maybe from how he is laying down? Put Neosporin on the areas where I could see the pink skin. The area is not bleeding... just dry and flaky with the hair missing. Logan has been on thyroid medication for over a year. Have not tested again to see if he needs a high dose. Logan is 12 years old. Any feedback is appreciated!
