When a brown recluse spider bites, it releases venom that may not cause immediate symptoms. Signs can take 2–8 hours to appear, and the effects may continue to develop over several days as the venom damages surrounding tissue.

Because of this delayed progression, it’s important to seek veterinary care as soon as you notice any of the following early signs of a brown recluse spider bite,
