How to Treat a Scorpion Sting on a Dog

If you live in an area where scorpions are common, you’ve probably wondered how dangerous they are for pets—and more importantly, how to treat a scorpion sting on a dog if it ever happens. While most scorpions aren’t life-threatening to dogs, their stings can still be painful, and some species—particularly the Arizona bark scorpion—pose a more serious risk.

Here’s what you need to know about symptoms, treatment, and prevention of scorpion sting on a dog.

Are Scorpions Dangerous to Dogs?

According to research, the majority of scorpions don’t cause severe reactions in pets. Their venom is designed to subdue small prey like insects, so dogs typically experience localized pain, swelling, or numbness that can last up to 72 hours.

However, there’s one important exception: the Arizona bark scorpion. While many large dogs recover without complications, small dogs and cats are much more vulnerable to serious symptoms.

A small study from prestigious institutes support this: only 13% of larger dogs showed significant symptoms, compared to 39% of smaller dogs.

Symptoms of a Scorpion Sting in Dogs

The first four hours after the sting are the most important for evaluating your dog’s reaction.

Common signs include:

• A red mark at the sting site

• Limping or licking the paw

• Rubbing the nose or face on the ground

• Yelping, jumping, or sudden pain

Small dogs may show additional symptoms such as:

• Difficulty breathing

• Excess drooling

• Dilated or watery eyes

• Restlessness

• Tremors or shaking

Arizona bark scorpion stings can cause even more severe symptoms, including:

• Pale or gray gums

• Sudden vomiting or diarrhea

• Collapse

• Intense muscle twitching

How to Treat a Scorpion Sting on a Dog

What you do next depends on the type of scorpion and the severity of symptoms.

1. Seek Veterinary Care Immediately for Severe Symptoms

If your dog shows any serious signs—especially those associated with the Arizona bark scorpion—head to your veterinarian or an emergency clinic right away.

2. For Mild Symptoms: Clean and Soothe the Sting

If the scorpion was not an Arizona bark and your dog is only mildly irritated:

• Gently wash the sting area with warm water and mild soap.

• Apply a cool compress to soothe pain and swelling.

• Contact your vet for guidance—especially if you notice an embedded stinger.

• Your veterinarian may recommend an antihistamine like Benadryl (never give medication without professional direction).

3. Photograph the Scorpion

If you can safely do so, snap a photo of the scorpion (before or after “smooshing,”). This helps your veterinarian determine whether the sting could be dangerous.

In many cases, your vet may advise monitoring your dog at home. Most pets recover well with rest, comfort, and time.

Veterinary Treatment for Scorpion Stings

Dogs with more severe reactions may need:

• IV fluids

• Epinephrine

• Diphenhydramine (Benadryl)

• Pain management or other supportive care

An antivenom exists for Arizona bark scorpion stings, though it is expensive, rarely stocked in veterinary clinics, and most effective when given within 10–20 minutes of the sting. In emergencies, veterinarians may access antivenom through a human trauma center.

How to Prevent Scorpion Stings in Dogs

Since scorpions are most active at night, prevention is key:

• Use a black light, which makes scorpions glow, during nighttime walks.

• Keep your yard tidy—scorpions hide under boards, rocks, logs, and clutter.

• Check bushes, walls, and tree bark for Arizona bark scorpions.

• Seal gaps and entry points around your home.

• Shake out dog bedding, blankets, and shoes regularly.

• Be especially careful when scorpions may enter in search of water.

If you have recurring scorpion sightings, contacting a professional exterminator is often the safest option.

Final Thoughts

Knowing how to treat a scorpion sting on a dog can help you react quickly and confidently during a stressful moment. Most stings cause only mild discomfort, but it’s always better to err on the side of caution—especially with small dogs or when the culprit could be an Arizona bark scorpion.
