It sounds like Pluto has an ear infection and I would recommend to take him to the veterinarian as soon as you can. Infections can be painful, can damage the ear drum, causing hearing loss and can even cause calcification of the ear canal (which is very painful). The vet will look at a sample under the microscope to determine what type of infection is present and what kind of medication is needed.
Pets have have chronic ear infections may have underlying allergies or endocrine disease which causes them to be more prone to getting an infection. Talk to your vet about exploring these options. I hope this helps and thank you for Petco Pet Education Center, formerly Petcoach.
