how do dogs get rabies

Rabies is a very frightening disease that causes plenty of concern among dog owners.

Pet parents may not only wonder how dogs get rabies, but what they can do to prevent their pet from contracting the disease too. For that matter, owners may worry about being exposed to the disease themselves.

We’ll answer these questions and explain some other important details about rabies below. Let’s jump right it!

What Is Rabies? What Causes the Disease?

Rabies is a viral disease caused by a type of RNA virus called a lyssavirus. Most cases are caused by one known simply as Rabies lyssavirus or the rabies virus. However, Australian bat lyssavirus can also cause the disease.

Once animals contract the rabies virus, it travels to the nervous system, where it begins to replicate. Soon thereafter, the disease makes its way to spinal column and ultimately the brain, where it begins triggering symptoms. Eventually, the virus will move to the infected animal’s salivary glands, where it can then be transmitted to other animals.

It is important to note that rabies is a zoonotic disease, meaning that humans can catch it from animals. So, it is not only an important topic for all humans to understand — not just dog owners.

Unfortunately, the disease is almost always fatal once the symptoms of rabies appear, thus highlighting the importance of prevention. Fortunately, rabies vaccines are readily available in most developed countries, making rabies deaths pretty easy to avoid.

How Do Dogs Get Rabies? Where Does It Come From?

Rabies is a common disease that plagues a variety of warm-blooded animals, with bats, raccoons, and skunks serving as a few of the most common carriers.

Animals infected with rabies pass it along to other animals through their saliva. Infected animals are generally only contagious once they begin displaying symptoms, but you should still have your pet examined by a vet if he’s bitten by a wild animal.

Note that while dogs in the United States most commonly contract rabies from wild animals, this isn’t the case across the world. Lacking the widespread rabies vaccination programs the U.S. (and many other countries) enjoy, dogs hailing from many developing countries commonly contract rabies from other dogs.

Good News / Bad News

Unfortunately, once they begin displaying symptoms of rabies, dogs typically only live for about a week. However, while this is obviously sad, it does mean the dog won’t have very much time to spread the disease to others.

Common Ways For Dogs to Get Rabies

Dogs (or any domestic animal, really) can get rabies in one of two primary ways:

  • Animal Bites: The most common method for getting rabies is through a bite from an infected animal. High levels of the virus are usually present in an infected animal’s saliva. If an animal that carries the virus bites the dog, there is a high possibility that the dog will contract the virus as well.
  • Animal Scratches: A scratch may also cause the infection to spread from one animal to another, if saliva comes into direct contact with a wound (the scratch itself won’t transmit the virus, but it’ll provide a route by which saliva can contaminate the wound). In fact, dogs with any type of open wound can also catch the disease if the other animal’s saliva comes in contact with it.

Though it isn’t as common, dogs may also contract rabies if the saliva from an infected animal comes into direct contact with one of the dog’s mucous membranes (such as the nose, mouth, or eyes).

How to Prevent Rabies in Dogs

Cheap Pet Vaccines

Rabies is certainly scary, but fortunately, it’s pretty easy to prevent in the industrialized world.

Have your pet vaccinated.

The best way to prevent rabies is to have your pet vaccinated against the disease. All dogs (and cats) should receive the rabies vaccine, as should people who are at higher risk of contracting the virus (just speak with your doctor if you think you’re at high risk). 

In many states, rabies vaccinations are required for pets, while some regions delegate that ruling to the county. Regardless, you should get your pet vaccinated for their safety and for the safety of you and others.

Different states require slightly different rabies vaccine regimens, with most recommending the first dose at around 14 weeks of age, with a follow up at 1 year of age. Just be sure that you don’t get your dog’s first rabies vaccination before he’s 12 weeks old, as it will be unlikely to prove effective.

Keep your canine contained.

Another way to prevent dogs from getting rabies is to keep them leashed whenever they’re not inside or in a fenced yard.

Of course, bats can certainly fly over fences and raccoons often climb over them, so your dog is still at some risk of contracting rabies, even when in your fenced backyard. But by preventing your dog from roaming wildly, you’ll drastically reduce the chances of him contracting rabies.

Keep your distance from stray dogs and wild animals.

It is also best to stay away from stray animals, feral dogs, and other wild animals. Some may seem friendly, but there is no way to tell whether or not the four-footer ambling toward you is a rabid animal or not.

In fact, because of the way rabies can alter the behavior of an infected animal, “friendliness” is often better described as a lack of fear — one of the common signs of a rabies infection. Similarly, you’ll want to be cautious around animals who’re normally nocturnal, being active during the daytime.

Predator Protection

Coyotes certainly represent a predatory threat to small doggos, but because they can carry rabies, they can even represent a threat to bigger pooches too.

So, if you must allow your dog to walk unattended in the backyard, you’ll want to keep him as protected as is possible. And in many areas, that means using coyote deterrents and repellents.

Many of these tools will help prevent your canine from getting dog-napped by a hungry ‘yote, but they may also provide some protection from bites (and therefore rabies). Some may even cause coyotes to look elsewhere for an easier meal.

You should still have your pup vaccinated and monitor him as much as is possible, but these types of tools can offer supplemental value.

Clinical Signs and Symptoms of Rabies

While some dogs can begin displaying the clinical signs and symptoms of rabies very quickly following a bite, others may not show signs for quite a while — months or years later, in some cases.

A lot of the discrepancy in the time frame relates to the location of the bite. Those located closer to the brain typically cause symptoms to manifest more quickly than those that occur in the extremities.

Here are some symptoms of rabies:

  • Increased aggression or irritability
  • Excessive drooling
  • Frothy, white substance seen at corners of mouth
  • Coughing or throwing up white foam
  • Difficulty swallowing
  • Lack of muscle coordination
  • Paralysis
  • Seizures
  • Fever
  • Change in how a dog’s bark sounds

Rabies is a serious disease that needs to be treated as such. It is important for dog owners to keep a close eye on their pets so they do not come in contact with wild animals that could carry rabies.

Dog owners should do everything in their power to prevent their dogs from getting rabies, and take them to a veterinarian right away if any symptoms are detected.

The ultimate thing to remember: Always get your dog vaccinated against rabies!

Two Manifestations of Rabies

It is important to note that rabies occurs in two different forms: “Furious” rabies and “dumb” or “paralytic” rabies.

Furious rabies is what most people picture when thinking about the disease. It causes dogs to bite and become very aggressive (hence its other name: “mad-dog rabies”). These animals may also drool excessively, snap at imaginary bugs, and seem incredibly agitated.

By contrast, dumb rabies usually causes afflicted animals to exhibit no fear, and they’ll often display poor coordination. The dumb form is pretty rare in canines, but it does occur from time to time.

What to Do if Your Dog Gets Rabies

If a dog gets bit by another animal who you know or suspect is infected with rabies, he needs to be taken to the veterinarian immediately.

Your veterinarian will explain the recommended procedure (which may be mandated by your local health department), but the CDC recommends that:

  • Dogs with an up-to-date rabies vaccination status should be promptly re-vaccinated and then quarantined (in the custody of the owner) for 45 days. The dog should be evaluated by a veterinarian if any symptoms of illness develop during this time. If the veterinarian determines that the signs are suggestive of rabies, the dog should be euthanized and then tested. The health department should also be notified in such cases.
  • Dogs who’ve been verifiably vaccinated at least once, but may be behind on booster shots are treated similarly; they should be vaccinated, kept under the owner’s control for 45 days, and observed for signs of illness. If a veterinarian determines the signs are likely to be due to rabies, the animal should be euthanized and submitted for testing. The health department should also be notified.
  • Dogs who’ve never been vaccinated should be euthanized immediately. If the owner is unwilling to have the dog euthanized, the animal must be vaccinated immediately and then placed in a 120-day quarantine. As in the other cases, the dog should be observed and seen by a veterinarian if symptoms develop.

Generally speaking, dogs who’ve been vaccinated (and sufficiently boosted) are very unlikely to become sick; but dogs who have not been properly vaccinated are unlikely to survive. As noted above, you should always get your dog vaccinated against rabies, since rabies infection is fatal.

It is best to put a dog with suspected rabies into a carrier or cage for transport (if it is safe to do so — you don’t want to become exposed to the virus yourself). If the dog is already acting viciously and attacking, then the owner must call animal control to have them transport the dog safely.

It is also important to disinfect all areas of the home that the dog’s saliva could have come in contact with. Failing to do so could mean spreading the infection, especially for anyone who has an open wound or even simple scratch on their bodies.

Use preventive measures to protect you and your pets from this horrific disease.

What Should You Do if YOU Are Bitten by a Rabid Dog or Animal

Of course, your dog isn’t the only one who has to be concerned about potential rabies exposures — you are also at risk of the contracting the disease. But as with your dog, there are things you can do to protect yourself:

  • Keep your distance from unknown dogs and cats, as well as wild animals. Limiting your potential exposure to rabies is the best way to avoid contracting it in the first place.
  • If you are scratched or bitten by an unknown animal (or the animal’s saliva enters an open wound of any kind), wash the wound vigorously with soap and water. Then, contact your doctor or visit the emergency room immediately. As with dogs who’re exposed, you may also need to alert the health department to your potential exposure.
  • Ideally, you’ll bring the offending animal in for testing. Now obviously, this is a risky proposition in some cases — you don’t want to risk more bites or further injury by trying to wrangle a wild fox or raccoon. However, if you can safely capture the animal, it can be observed or euthanized and tested for rabies, which may (if the tests turn out negative) allow you to avoid having to be vaccinated yourself. If you aren’t able to capture the animal safely, simply contact an animal control officer or the appropriate authority in your area.

There is a human vaccine for rabies. It – along with immunoglobulin medications — is typically administered (several times) to people who’ve potentially been exposed to the disease. However, it is also given prophylactically (as a preventative) to people who are at unusually high risk of exposure to the virus. This includes veterinarians, wildlife control officials, and people who live in close proximity to rabid animals.
