If you’ve got Wolf Spiders in your area, and you own dogs, you’re probably concerned…

We often get messages from worried owners about interactions between their dog or puppy with a wolf spider, and whether or not they’re dangerous.

Our guide runs through the absolute most important questions on this topic and simplifies when and when it isn’t time to worry. Let’s get started.

Are Wolf Spiders Poisonous to Dogs?

Yes, wolf spiders are poisonous, but not in a way that’s typically dangerous to dogs.

The venom of a wolf spider is designed to incapacitate their small prey and is not generally potent enough to cause serious harm to a dog.

The Wolf Spider’s venom can cause irritation and discomfort in dogs, but it’s not potent enough to cause severe illness or death.

While their venom isn’t usually harmful to dogs, it’s still not a great experience for your dog to get bitten.

If you notice your dog has been bitten by a wolf spider, you’ll want to monitor them for symptoms like redness, swelling, or excessive itching at the bite site.

If these symptoms persist or if your dog seems unusually lethargic or sick, it’s a good idea to contact your vet.

What Happens if a Dog Eats a Wolf Spider?

Firstly, let’s reassure you – if your dog has eaten a wolf spider, there’s usually no need to panic.

Many dogs will naturally want to chase and eat bugs, including spiders.

It’s generally part of their nature to be curious and investigate moving things, and that sometimes means eating them.

Eating a wolf spider shouldn’t cause any serious harm to your dog.

However, there can be some minor side effects. The spider’s venom could cause a mild upset stomach or diarrhea.

Some dogs might also vomit if the spider disagrees with them. This will be different from dog to dog.

As long as these symptoms don’t persist for more than a day or two, there’s usually no reason to worry. But as always, if you’re concerned, it’s best to reach out to your vet.

How Can I Protect My Dog from Wolf Spiders?

The good news is that there are many simple steps you can take to keep your dog safe from wolf spiders:

  • Regularly clean your home and yard: Wolf spiders are attracted to clutter and messes because they provide a good hiding place. By keeping your home and yard clean and tidy, you can reduce the likelihood of wolf spiders setting up shop.
  • Seal cracks and crevices: Wolf spiders can find their way into your home through cracks, crevices, and other small openings. By sealing these up, you can prevent them from getting in.
  • Use spider repellents: There are many natural spider repellents available that are safe to use around pets. Essential oils are a good option, but ensure that it’s one safe for dogs.

Are Certain Dog Breeds More Susceptible to Spider Bites?

All dogs can be bitten by spiders, but certain breeds may be more susceptible due to their nature and size.

Dogs that are smaller, curious, or like to stick their noses into holes and under rocks are more likely to encounter a spider.

Breeds like Dachshunds, Beagles, or Terriers, known for their curious and exploratory natures, may be more prone to getting bitten.

That said, any dog, regardless of breed, could be at risk if they happen to come across a spider.

It’s essential to watch out for any signs of a spider bite on your dog, like redness, swelling, or changes in behavior, regardless of what breed they are.

Can a Dog Have an Allergic Reaction to a Spider Bite?

Just like humans, dogs can also have allergic reactions to spider bites.

While allergic reactions are not common, they can be severe in some cases.

Signs of an allergic reaction can include difficulty breathing, swelling of the face, or a sudden bout of vomiting or diarrhea.

In such situations, it’s essential to get your dog to a vet immediately as anaphylaxis can be life-threatening.


Wolf spiders can indeed be a cause for concern for dog owners, but the risk they pose is usually relatively low.

Their venom is not typically dangerous to dogs, and while a spider bite or ingestion might cause some discomfort, it’s unlikely to be seriously harmful.

To protect your dog from wolf spiders, maintain cleanliness, seal off entrances to your home, and use pet-safe spider repellents.

Watch out for any symptoms of a spider bite or allergic reaction in your dog, and consult your vet if you’re concerned.

While wolf spiders might seem scary, with the right precautions, you can keep your furry friend safe and sound.
