I noticed this bump on my dogs (will be 5 years old in June, spayed female German Shepherd, up to date on vaccines, given simparica trio last week) ear tonight. I don’t think it has been there long seeing as it’s visible and I rub her ears often when she’s laying next to me. I did put pressure on it while trying to get pictures and there appears to be a tiny hole in which a small amount of fluid, light blood and some matter came out of. She went to daycare last week seeing as we are going out of town for a week and will need to board her while we’re away so I’m not sure if she was injured during play.
