My dog has a hard lump on her ear after a tick bite. Is it normal?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Female | spayed | 1 year and 4 months old | 83 lbs

My dog was bitten by a tick over two weeks ago, on the flappy part of her ear. We removed the tick, it was intact and alive. A few days later we noticed a lump. On the bite location. It's hard and firm and skin coloured. It's not red, puss filled or irritated. She is eating and drinking no problems with her other wise.

The lump is likely a reaction to the bite and the anticoagulant injected by the tick. It can take a few weeks for the lump to go away. Just monitor it for infection/pus/pain. If those signs appear, have your veterinarian examine the lump.
