Is it a snake bite or something else?

Many snakebites are unwitnessed, leaving pet owners only wondering what could have happened. A variety of other conditions can resemble snake bites, so we have included several photos of these below.

Anaphylaxis – This is a severe allergic reaction characterized by hives, facial swelling, vomiting, diarrhea, and collapse.

Spider Bite – Spiders have venom similar to snakes but are often less likely to cause life threatening illness. Spider bites can cause tissue swelling and necrosis, like some snake bites:

Bee Sting – Dogs love trying to eat bees and often get stung in the face. This can lead to hives and severe facial swelling secondary to an allergic reaction.

Cellulitis – This is a condition of severe infection/inflammation of the skin. Clinical signs can mimic a snake bite with severe swelling and oozing.
