My dog had a tick above his eye and we removed it 2 1/2 weeks ago. Today I noticed a bump where it was. When I touched it the fur fell off. It had a small scab that fell off as well. The bump doesn't seem to be causing any pain. I put antibiotic ointment on it. Is this some thing I should take him to the vet for or just keep an eye on it in case it gets worse? I have added some pics if that helps. Thank you.
