My dog's ear lump keeps refilling with blood and pus. What to do?

Pet's info: Dog | Labrador Retriever | Male | neutered | 11 years and 9 months old | 75 lbs

My 11 yr old black lab has a lump in the lobe part of his ear. It filled up with blood and pus. I lanced & drained it but within a day or 2 it filled up again.. I bought medicine for him and have been keeping it cleaned. But now I'm not sure what I can do. It only seems to bother him a little but it is huge again from all the pressure in it

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. I would not recommend lancing the ear at home as this risks introduction of harmful bacteria that will cause an infection. I would recommend having this examined by a veterinarian as Jack will likely need an oral antibiotic and the ear drained properly. Sometimes the ear needs to have a drain surgically placed into the hematoma site so that it is unable to fill back up. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
