Scorpion Sting on a Dog: Symptoms and What To Do

Most scorpion stings amount to a very bad afternoon. A few species turn it into something else, so the job is watching rather than panicking.

A scorpion sting sounds far worse than it usually is. For most dogs, in most places, it amounts to sharp local pain, some drooling and a thoroughly indignant animal.

The reason it still earns a page is that a small number of species are genuinely dangerous, and the difference does not show up in the first few minutes. So the sensible approach is neither panic nor dismissal. It is to ring, and then to watch properly for a few hours.

What to do

1. Ring your vet or a poison line and describe what happened and where you are, since the species that matter are regional.
2. Watch closely for neurological signs over the next several hours.
3. If anything on the serious list appears, go in immediately.

In the US, the Pet Poison Helpline.

The usual version

Scorpion venom is a mix of neurotoxins and proteins. In the common, mild case the effects stay local:

• Drooling at and around the sting
• Obvious pain, often a yelp then licking or favouring a paw
• Itchiness
• Redness at the site

Most of these dogs are managed with supportive care and are much better within a day. A sting on the paw or the muzzle is by far the most common, because that is what a dog investigates with.

The version that needs a vet now

The Arizona bark scorpion is the most venomous species in North America and can produce a much more serious picture. Signs that the sting has gone beyond local irritation include:

• Dilated pupils
• An abnormal heart rate or blood pressure
• Tremors
• Wobbliness and poor coordination
• Unusual, flicking eye movements

That last one is worth knowing specifically, because abnormal eye movement is an odd, distinctive sign that owners often notice and dismiss as the dog being unsettled. Combined with tremors or wobbliness, it means the venom is having a systemic effect and the dog needs to be seen.

What not to do

Do not try to catch or handle the scorpion. You will very likely be stung yourself, and identification is not worth it.

Do not try to make your dog sick. This is an envenomation, not something swallowed, so there is nothing in the stomach to bring up.

And do not decide it is mild before you have actually watched for the serious signs and spoken to somebody. The first fifteen minutes look the same either way.

Where they are, and where they hide

Scorpions are found in the desert regions of the southwestern United States and Mexico, and across parts of North Africa, the Middle East and southern Europe, mostly in the warm months.

What matters practically is where they shelter overnight, because that is where dogs meet them. They tuck themselves into shoes, folded bedding, rubble, woodpiles and the underside of outdoor furniture.

If you are travelling somewhere they live, a few habits cover most of the risk. Shake out shoes before anyone puts them on, check bedding before a dog settles into it, and keep dogs from nosing under garden furniture, decking and rock piles after dark. A torch on the last garden trip of the evening is not excessive in scorpion country.

What to tell them

Where you were, and if you saw it, what it looked like, particularly whether it was small and pale rather than large and dark. The more dangerous species in North America is the smaller, lighter one, which is the opposite of what people expect.

Also say whether the sting was to the face or mouth, since swelling there is worth watching more closely.

Living somewhere they live

If you have moved somewhere with scorpions, the habits are worth building deliberately rather than after an incident.

Shake out shoes and boots before anyone puts them on. Lift and check dog beds and blankets that have been on a floor or a patio overnight. Keep woodpiles and rubble away from the house and away from wherever the dog sleeps. Use a torch for the last garden trip of the night, and check under outdoor furniture before letting a dog nose around it.

None of that is excessive in scorpion country. It is just what living there involves once you have a dog.
