Can a Lump Occur after Tick Bite in Dogs?


ump on dog after tick bite– a phenomenon quite common and considered to be normal. Some animals experience a bite without the formation of seals, which is also a norm.

With a very rapid response of the body the lump can be similar in size to cherries, but not larger. It doesn’t hurt or fester. Externally, the skin in this place is usually pink or red. When touching, the cone is dense and fairly firm, of homogeneous structure.

As the suppuration develops, the cone becomes doggy and large lump on dog after tick bite increases in size to a cherry tomato. Its soreness increases, and the skin becomes red. During closer inspection, you can sometimes see a point on the cone that looks like an almost healed wound or a clogged pore. If there is such point, then it is necessary to put Ichthyol ointment, which will quickly pull the pus. When there is no such point, it means that the abscess will not be able to break through naturally, and its surgical opening is necessary. The operation is performed under local anesthesia. The abscess is opened, and its cavity is cleaned and treated with an antiseptic. Then, the sore spot should be every day smeared with Brilliant Green to complete healing, which usually takes about 10-14 days.
  3. Infection. It occurs if during the removal of the tick or after that, until the wound is healed, an infection gets into it.  In this case a bump becomes visible in a few days.
