Home remedies can be really helpful, but what can remedy a spider bite on your dog? Depending on the species, spider bites can pose a severe threat to your dog. Many times, a dog getting bitten is unavoidable. Being proactive and getting familiar with the different types of poisonous spiders can make all the difference.

Recognizing the spiders and their bites can keep your dog from unnecessary harm. Keep reading for an in-depth explanation of how spider bites may affect your dog and what you can do at home if your dog is bitten.

What is a Spider Bite?

A spider bite, or the more technical term arachnidism, is simply a wound that comes from being bitten by a spider. Most of the time, spider bites are harmless. Typically, a spider will not bite unless they're in danger or perceive a threat.

Even the bites we think come from spiders, usually end up being from other bugs. At times, skin infections or hives have also been mistaken for spider bites.

Some spider bites can cause itchiness, swelling, redness, and pain. Other times your dog might not even notice they have a spider bite. Although, with more than 30,000 species of spiders, there are some dangerous ones to be aware of. Luckily, you and your canine only need to worry about two threatening spiders if you live in North America.

Both the black widow and the brown recluse have fangs long enough to penetrate the skin and inject their venomous toxin, the hobo spider can also envenomate an animal, though this is rarer and the bites are not deadly; however, localized tissue irritation and possible necrosis can occur.

If you or your dog gets bitten by either one of these spiders you should immediately seek medical attention. To help us distinguish the difference between a common spider bite and a dangerous one we will need to go over all the symptoms of spider bites and how to identify them.

What Does a Spider Bite Look Like on Dogs?

Before using home remedies for a spider bite you need to make sure your dog was actually bitten. You see, identifying a spider bite on a dog can get tricky.

Most times a common spider bite will resemble a bite from any other insect and there's no need to raise immediate concern. If the symptoms seem intense or get worse you should take your dog to the vet. Some typical signs of spider bites to be aware of are:

  • Diarrhea
  • Vomiting
  • Tremors
  • Pale Gums
  • Anxiousness
  • Limping
  • Muscle pain
  • Drooling
  • Itchiness
  • Swelling and redness
  • Trouble walking or standing
  • A bull's eye mark or a blister
  • Weak pulse or increased heart rate

Depending on which species of spider delivered the bite, symptoms can vary. Most bites will include signs of irritation, redness, and swelling.

If a lot of venom is released at the time of the bite, symptoms might also include muscle pain, diarrhea, cramping, vomiting, tremors, and anxiousness.

Noticing a spider bite on a dog can be challenging, especially if the dog has a thick coat of fur. Before you identify a bite, you might see your dog becoming restless, yelping, or licking the affected area.

Paying attention to any differences or more advanced symptoms listed above can help you be more actionable.

What Are the Symptoms of Spider Bites on Dogs?

So, how can you tell if your dog has a spider bite? Signs of a spider bite can vary depending on which species did the biting. As noted earlier, there are two spiders that are poisonous to dogs in the U.S.

As a dog owner, the spider bites you need to be concerned with are the black widow and brown recluse.

Signs of a Black Widow Spider Bite

There are several signs to look for if your dog gets bitten by a black widow. A female black widow usually ranges between 2 and 2.5 cm in length.

They are a shiny black color and have an orange or red mark under their abdomen that resembles an “hourglass.” Males are generally considered non-toxic because of their smaller fangs. Dogs bitten by a black widow might display symptoms of the following:

  • Drooling
  • Vomiting
  • Diarrhea
  • Pale Gum Color
  • Cramping
  • Paralysis
  • Muscle Tremors
  • Severe muscle pain
  • Unbalanced walking
  • Abnormal blood pressure changes

The neurotoxins found in the black widow's venom (female) affect the dog's nervous system, which causes spasms or paralysis.

Smaller dogs are more prone to experience more serious symptoms.  Treatment for a female black widow bite requires a visit to the vet and usually includes an antivenin, IV fluids, pain medications, and anti-seizure medications.

If you suspect your dog has been bitten by a black widow, don’t hesitate, to call your veterinarian or Pet Poison Helpline (800-213-6680) immediately for life-saving care and advice.

It is not advised to only rely on home remedies if a black widow spider bites your dog.

Signs of a Brown Recluse Spider Bite

Signs that your dog was bitten by a brown recluse spider can include reluctance to put weight on the affected area, pawing or scratching at the body, head, neck, or ears, and localized swelling. Sudden limping or lifting one leg while standing can also be good initial indicators that a bite may have occurred on a leg/paw.

Another name for the brown recluse is the “violin spider” and the symptoms of its bite tend to get worse as time passes, depending on how severe it is. More severe symptoms can include:

  • Pain
  • Swelling
  • Blistering
  • Red, itchy skin
  • Skin lesion that mimics a bull's eye
  • Necrotic tissue (dead skin) around the bite (not seen immediately)
  • Gash or wound after the dead tissue falls off (not seen immediately)

To reduce the swelling and redness on your way to the vet, apply a cool compress, avoid ice packs as constant skin contact with ice packs can impair circulation and create localized hypothermia of the tissue and wreak more havoc.

The most common treatment for a brown recluse spider bite, in humans and dogs, may include a medication called dapsone; however, your veterinarian would be the best to prescribe the best treatment.

Your vet might prescribe corticosteroids to prevent further necrosis from happening. It also helps contain the venom within the infected cells, keeping it from spreading.


Antibiotics & Antiseptics

Antibiotics and an antiseptic are usually given to the dog to prevent secondary infections. The wounds left behind from a brown recluse bite will most likely need to be bandaged.

If you suspect your dog has been bitten by a brown recluse immediately call your veterinarian or Pet Poison Helpline (800-213-6680) for life-saving care and advice.

It is not advised to only rely on home remedies if a violin spider bites your dog.

Both the brown recluse and black widow spiders live in areas that remain undisturbed. They will not bite unless threatened, and in fact, they need some pressure to inject their venom. Sitting, stepping, lying or accidentally disturbing them can cause them to bite.


Which Dogs Are Affected by Spider Bites?

All dogs are at risk when bitten by a poisonous spider like the black widow and brown recluse. However, older dogs are more at risk of deadly reactions to spider bites due to their weaker immune systems. Dogs who have high blood pressure are also more at risk.

Use Aloe Vera to Soothe the Area

Just mix up some water and salt and dip the cloth in it then use it to dress the wound and let it soak for a few hours.
