Hello my bulldog really sense we adopted him in June has had a butt itching issue he would sit and spin and spin in circles and he does this like 10 times a day and can't figure out why. He did have a pollup in his butt when we got him and I though that was the reason then. He does not have fleas I have yet to see one on him. He does not have ticks. His anal glands were expressed first time sense we had him Monday and seems to continue which left it at tail pocket. I do clean it about twice a week and it is so dirty when I do. So past few days I been cleaning it daily and it isn't as bad but still is dirty. He does the spinning thing outside when I take him for a walk so that could be where it is.coming from. I did look in there and his tail is slightly a reddish color which maybe comes from the dirt? I have no clue I clean it with baby wipes and dry with paper towel. Could it be allergies? Anyone have any suggestions?
