I found a tick on my dog's forehead about 2 weeks ago. I removed the tick, actually 2 ticks right next to each other, and put them in alcohol to kill them. There was some bleeding and I cleaned the area of where the ticks were. After the ticks died, I put them into a baggy in case she got sick, so I had them for reference. She has been herself, since then with no problems. Though the area of where the ticks were is still scarred, and the scar seems bigger. I don't get that?? I've given her flea/tick medicine about 3 days after the tick removal, so that was supposed to prevent any other ticks from biting on. Is she having some sort of reaction, what would be the cause of the scar growing?
