There are lots of compelling reasons to vaccinate your pets on a schedule developed by you and your veterinarian, but perhaps the most compelling-est is to avoid having your pet beheaded. You read that right – beheaded, just like Anne Boleyn.
For animals that have bitten a person, a 10-day quarantine is the usual way of determining if they have rabies. Quarantine is not all that bad; it’s kind of like an all-inclusive resort weekend, except instead of tuxedoed waiters and umbrella drinks it’s dry kibble and an animal control cage. Actually, that sounds more like prison than a sunny Bahamas resort, more three hots and a cot than all-you-can-eat steamed shrimp. The logic behind the 10-day stretch that you pay for is that very, very few animals that are rabid and shedding virus in saliva (more on this below) will live past 10 days. If your dog bites you or someone else and survives for longer than 10 days, the chances that your dog was rabid at the time of the bite are essentially nil.
But before that, it would probably behoove me to spend a few words talking about why we bother vaccinating against rabies in the first place. Rabies is a viral neurological disease that any mammal can pass on to any other mammal through an infected bite or contact with saliva that contains wee little rabies particles called virions. Yes, technically, you could contract rabies from a narwhal or a wallaby, but it prefers to spend its time inside more commonly found hosts, mammals like foxes, skunks and bats. Those three species are the canonical wild mammals that rabies uses as hosts – the Groucho, Harpo and Chico of the rabies world. Every once in a while (and it varies by region) a new critter will emerge for a while as a carrier of the dread pirate rabies, like Zeppo sneaking into a Marx Brothers movie. Dogs, cats, cows, horses, llamas and all of our domestic animals can contract rabies and spread it to us.
The rabies virus is a cagey little bit of fluff. Once an animal is bitten, the virus travels up the nerves in an all-roads-lead-to-Rome fashion until it reaches the central nervous system and the brain. Once there, it sets up shop in the very part of the brain that controls emotion and pushes the shiny red ‘rage’ button; animals become aggressive and more likely to bite. The virus also starts to reproduce in the salivary glands, which produces the classic ‘foaming at the mouth’ vision of a rabid dog. What better way to pass on the disease to a new host than to ramp up the transmission machinery (saliva) and make the carrier prone to injecting it into the next unlucky victim through a bite? Rabid animals have literally had their brains taken over by the virus, becoming a raging guided missile of viral transmission. No wonder most zombie movies and stories use a genetically modified rabies virus as a plot point.
The other part of the whole rabies thing is…less savory.
Actually, it is downright horrifying and fairly disgusting, so let’s give in to our prurient side and dive right in.
Since our domestic species tend to canoodle with wild animals from time to time, we can and do get rabies. Our public health folks think of vaccinating our dogs and cats against rabies more of a way of protecting us humans than of protecting the pets.
Sure, you don’t want your pet to get rabies, but the public health folks are more concerned with making sure your dog doesn’t catch rabies from a fox who was in the back yard and then passing it on to every kid in the neighborhood. Thus, the rabies vaccine was invented and has become the only legally mandated vaccine for pets; other vaccines, for diseases like parvo and distemper, are medically necessary for the pets but don’t play a role in public health.
So…10-day quarantine if your dog bites someone. Seems simple enough, eh? But what if your dog was to die or be euthanized during that 10-day period? What if your dog bit you because you picked her up after she was injured when hit by a car? It may seem a bit far-fetched, but this scenario happens all the time in veterinary ERs. Animals are far more prone to bite when they are injured, sick, or handled by strangers than when on their home turf, and so veterinarians and staff face this scenario frequently. (One of the things in small print on the forms that veterinarians ask owners to sign before euthanizing pets is for the owner to ascertain that their pet has not bitten anyone in the past 14 days.)
When we euthanize a pet that has bitten someone recently, there is obviously no chance to see if the pet would survive the 10-day period. Using the example of the injured dog that has bitten her owner, if the dog has a broken back and the owner elects to euthanize, we don’t know if the dog was rabid when she bit her owner. Actually, we can find out, and here is where things turn from sad to outright gruesome. What is to follow can only be described as unsettling and potentially offensive, so please read on with caution.
The only definitive way to determine if an animal had rabies is to examine the brain. This is impossible to do while alive. Blood and other ante-mortem (before death) tests are not reliable enough when a human life is on the line. This means cutting the head off and submitting it to a state lab for rabies testing. This testing is not optional if your pet is not currently vaccinated for rabies. If an unvaccinated animal bites a human and then either dies or is euthanized, the head must, by law, be submitted for testing. This all seems quite matter-of-fact and clinical when writing about it for a blog post, but for the veterinarian in charge and the pet owner, it really gets uncomfortable and downright ugly – trust me.
There is some wiggle room in this scenario ‒ in certain jurisdictions, and with certain animal control agencies ‒ to avoid testing the brain if two criteria are met:
- The pet has a current vaccine for rabies: first one given after 6 months of age, next one a year after that, then every 3 years.
- The bite was a "provoked bite," delivered because the animal had a logical reason to do so, such as has a broken back. An unprovoked bite is what rabid animals are likely to do: just come up and chomp for no reason at all.
I am not saying that you can avoid testing in all cases if your pet is current on rabies vaccination, but I have been able to get a sympathetic animal control officer to relent when I have described the situation to them and pleaded on the owner’s behalf. Not every time, mind you. Some officials are by-the-book sticklers and will demand that the pet’s head be submitted regardless of vaccine status or the situation surrounding the bite.
Imagine for a moment that your dog was just hit by a car and is lying injured in the street. It is the usual first instinct of loving owners to rush to the dog and pick her up. If your pet bites you, and you later determine that euthanasia is the most humane option, most veterinarians will be forced to submit the head for rabies testing if your dog is unvaccinated for rabies. In the midst of the pain and shock at seeing your pet injured, suffering a bite yourself and making the agonizing decision to euthanize the pet, you now face the horrifying knowledge that she has to have her head cut off. It is almost too much to take, and even though every word of this is true, I feel like I am betraying a sacred trust in exposing this fact. I admit that several times over the course of my career, I have used the euphemism “take a sample of nerve tissue” for owners who I didn’t think could cope with the actual truth of what would happen to the remains.
The job of removing the pet’s head is unpleasant and is physically and emotionally draining. Despite what you may have seen in the movies, heads like to stay on and removing one is hard work. The task is so terrible that it is often passed on to junior staff members like interns. I have had to do it many times, and I detest it each time. Veterinarians are trained to heal animals, not cut their heads off. It seems like the ultimate failure.
Domestic animals don’t often test positive for rabies, but when they do the consequences are dire. The situations I outline here don’t come up often, but are seen often enough that it is worth making sure that your pet stays current on rabies vaccines. Protecting your pet’s dignity after death is one more thing in the long list of reasons why a current rabies vaccination is important.
Editor's note: A bobcat that attacked two people in their garage tested positive for rabies.

We made the toughest decision of our lives to put our boy DJ down today. As we took him to the vet and my husband went to get him out of the truck, mind you our boy was in a lot of pain due to his bad hips and not eating for a few days. Our boy bite my husband (owner) as soon as it happened with NO sympathy they told us they had to report it and take his brain for testing. Our dog gets his shots when needed never missed one! He is up to date on ALL vaccines! What was meant fo be a sad day to just mourn our boy it turned out to just be hurt and major anger inside! I feel like we are being punished! Why I don’t know? This law needs to be put on the back burner for all animals who are fully vaccinated!!!!! Our boy does not deserve this. I feel like we are just going to get back nothing now. And on top of it all THIS IS AT OUR EXPENSE! I am disgusted and mortified that this such thing exists! Once I get our boy back in our home I will be fighting back! also, 10 day quarantine was no option cause the way he was he would have just died at home suffering from the pain. He hasn’t eaten or gotten up. We were so broken to him like that. They put us in between a rock and a hard place and this was not fair at all. My heart goes out to all dog owners who have to go through this. ๐

Thanks for the additional info. While I think this may get into too much biological detail for the average layperson, I agree that the neuro dysfunction of the cranial nerves would be the root cause of the 'foaming'. The amazing part for me was the fact that the virus is:
- present in saliva
- makes the patient drool (making more little virions present themselves to the unfortunate victim)
- and makes the patient more aggressive
Which all conspire to make this one mean little mother of a virus - the perfect storm of factors to ensure that it gets passed on.
