My 3 never have dingleberries, their poop is very firm and it does not get stick to their hinneys. They don't get the "runs" unless they are sick but I can't tell you when the last time that happened. I take them to the groomer about every 6 weeks and 8 would be stretching it. When they go they have their back ends clipped really short what I like to call a sanitary shave. I don't even think it is a good idea to wipe a dog butt all the time like that. Please don't take this the wrong way but I think you are missing something since this is not normal~well at least in my house it isn't
