Pet Vaccines 101 - Common Canine Vaccines

Almost everyone has their pets vaccinated against a variety of diseases. I'm always surprised how few questions I get about what all those needle-pokes are for. Well, if you've ever wondered about the whole story on all those tiny little vials - this series is for you. The first two articles will cover what diseases we vaccinate in dogs, then cats. Then, we'll cover the questions I do get asked on a regular basis - like how often to vaccinate, how vaccines differ, and potential reactions to vaccines.

2009 animal rabies cases (CDC).
Rabies Virus
It's the big one that everyone is familiar with, thanks to the fact that rabies is pretty much 100% fatal once it becomes symptomatic - and therefore your pet is legally required to be vaccinated against it. Transmitted by saliva into open wounds, it travels to the brain where it causes neurological effects ranging from stupor and loss of coordination (the "dumb" form) to violent outbursts (the "vicious" form). The time from infection to symptoms can vary from weeks to several months; after symptoms develop it progresses to death fairly quickly, though.

Pretty much any mammal can get it and give it - to your dog, cat, ferret, or you. Fortunately, human and pet infections are rare in the US nowadays - thanks largely to vaccination. It is very present in the US, however; every state except Hawaii reports anywhere from a handful to hundreds of cases in wild animals annually. The most common carriers are bats, raccoons, skunks and the like.

"Parvo" Vaccine Complex
Pretty much all veterinarians use a combination vaccine that includes parvo, distemper, and hepatitis. These are discussed individually below. Some combo vaccines also include parainfluenza, which is discussed below under "kennel cough."

There are tons of variations on specific
vaccines and combinations.
  • Parvovirus: Most folks have heard of this one too, as it is the only disease we routinely vaccinate against that's still relatively common. The virus very efficiently destroys the cells lining the intestines; this leaves the dog unable to digest food, retain water, or keep intestinal bacteria from entering the bloodstream. A malnourished, dehydrated, septic puppy is generally a dead puppy without treatment. On the bright side, if caught early and treated aggressively dogs generally respond well - if they live long enough, they'll generally clear the virus on their own. However, several days in the hospital on intravenous fluids and antibiotics gets costly fast, and is by no means a guarantee.

  • Distemper Virus: About 50% of dogs who catch distemper will experience mild general malaise and/or respiratory disease. Unfortunately, the others will develop a potentially fatal infection of the brain and spine; those that survive often have serious long-term neurological problems. All affected dogs will experience severe suppression of the immune system - the virus first attacks white blood cells - and potentially life-threatening secondary infections often occur in any affected dog. You may not hear a lot about it, but it's out there - and it's not a disease to be trifled with.

  • Infectious Canine Hepatitis (Canine Adenovirus Type-1): This is a disease that primarily damages the liver, potentially fatally, but it may also affect the eyes, kidneys and other organs, or turn into a chronic, low-grade infection. Fortunately, it's very rare nowadays because of routine vaccination. Interestingly, the vaccine is actually CAV-2, a related virus that causes transient respiratory disease and is part of the "kennel cough" complex discussed below. CAV-2 vaccine provides good cross-protection against the more serious CAV-1, and the old CAV-1 vaccines had more frequent side effects.
Other, Non-Core Vaccines
  • "Kennel Cough" - Bordetella bronchiseptica & Parainfluenza Virus: "Kennel cough" is the common term for a group of upper respiratory infections that are generally self-limiting. They generally don't hang around in the environment long, and instead are passed between dogs in close quarters - most commonly, in kennels, at dog parks, or at events like shows or agility contests. Bordetella & parainfluenza are two of the more common culprits, and the primary ones we vaccinate against. They aren't consider "core" vaccines, since many dogs never board at a kennel and have minimal contact with other pets - but they are highly recommend for those who do, and required to stay at kennels.

  • Leptospirosis: Lepto is a bacterial disease that can shut down the kidneys and may damage other organs like the liver. That's bad. It's also something you can get, though good oral hygiene minimizes risks (making it mostly a concern for children). The majority of mammals can carry it, sometimes without major symptoms, and transmit it via urine. We all know what dogs do when they find urine, hence why they're prone to it. Risk levels vary from area to area, so talk to your veterinarian. However, if you travel with your pets it is a good idea regardless.

  • Lyme Disease: This bacterial disease is most commonly associated with severe arthritis, though it can also seriously damage organs such as the kidneys. It's transmitted by ticks, and is also known as borreliosis after the bacteria that causes it. This is another fairly region-specific disease, with the east coast and Great Lakes regions being at greatest risk, so talk to your vet.

Leaving On A Jet Plane - International Travel & Pets

Traveling across town to with your pet in the car can be an adventure; traveling outside the country with your pet can be like navigating between the Scylla and Charybdis. I should know. I currently run an Air Force clinic, and we help people get their furry family members overseas on a daily basis. Every single country in the world gets to make its own decisions about what hoops you need to jump through to import your pet. They also get to change them whenever they want.

This article is geared toward travel outside North America (including Hawaii). Mexico and Canada are fortunately pretty easy to travel between. For travel outside North America with your pet the best advice I can give you is this - start early (like yesterday), research thoroughly, and double-check everything. You will need at least a month's lead time, and for countries like Japan you may need six months or more.

This is also one situation where I'll tell you your veterinarian is not the expert; few vets ever send pets to Japan, let alone Moldova. They'll do everything they can to help, but ultimately it's your responsibility to become the expert and make sure everything Muffy needs to get where you're going is taken care of. This article should give you the tools to turn yourself into that expert. If you're serious about this, you might also start by make yourself a nice, calming cup of chamomile.

Before You Do Anything Else:
  1. Contact the consulate of the country you are traveling to; this is the horse's mouth, so to speak, when it comes to what is required to get into that country. You must do what they require or they can detain your pet. You must know what the current and specific requirements are. 

  2. APHIS is another good resource for export regulations. The country in question has the final word, but the Animal and Plant Health Inspection Service maintains information on most countries at the website above, which may (or may not) help to clarify instructions from the consulate.

  3. Research airlines. They all get to make their own rules about what can fly, how it flies, and how much it costs. Pets with significant health issues may be okay to fly in the cabin, but they should not fly in cargo - often that is the only option for international travel. Your flight plan is an additional consideration; if you have a layover in a country other than the destination you might need to make import arrangements for that country too.

  4. Check out this article for tips on making travel less stressful for you and your pet.
Things You WILL Need:
  1. Current rabies vaccination and certificate: Usually this must be done at least a month prior to travel, and for some countries can be six months or longer. This is currently all you need for Canada. Vaccination must also occur after microchip implantation.

  2. Veterinary health certificate: Your vet will need to examine your pet and sign a form attesting that they are in good health and free of disease. APHIS Form 7001 is good for general travel; however, many countries require special certificates (especially if English is not the national language). Contact the country's consulate or check with APHIS to be sure. 

  3. ISO Compliant microchip: Unfortunately, some US microchips may not work for international travel. ISO-compliant 134.2kHz chips are the current international standard. Check your pet's number, if it's 15 digits you're OK. If not, you'll need to get a new chip or bring a scanner with you. Excepting a few unique situations, I wouldn't recommend the later. A scanner costs $150-$200, and more importantly, if your pet were lost while traveling no one could read the chip to get them back to you.

  4. USDA endorsement: Generally, you will be required to visit your local USDA office after getting a health certificate from your regular vet. You do not need to bring your pet with you, just all the documentation. They will make sure everything is in order, which is great since small mistakes - which can lead to big problems at foreign airports - are easy to make in this process.
Things You MAY Need:
  1. Anti-Parasite Treatment: Many countries require treatment for parasites shortly before travel. This generally needs to be given by your veterinarian and attested to on the health certificate, so make the appointment with that in mind. As a side note, it may be worth considering a broad-spectrum deworming when you get home as a precaution against any unwanted stowaways in Muffy's gut. Talk to your vet.

  2. Other Vaccines: Since they all get to make their own rules, countries may require all sorts of vaccines or treatments. Guam, for instance, requires Coronavirus vaccination...which is pretty silly if you ask me, since the vaccine is junk and the disease isn't very serious. But no one asks me, and if you want to take your pet overseas you have to play by that country's rules, period. It's also a good idea to ask your vet if there's anything Muffy hasn't had that might be recommended - Bordetella (kennel cough) and leptospirosis in particular.

  3. FAVN (rabies) testing: This is a special blood test that verifies your pet has enough antibodies against rabies to prevent infection - in other words, that the pet was effectively vaccinated. It is required for import into most rabies-free countries and quite a few others as well. This often requires a lot of planning and time, since:
    • Your pet generally needs at least two prior rabies vaccinations, at least two weeks prior to testing.
    • At least one vaccination must happen after microchip implantation.
    • Getting results often takes 2-4 weeks.
    • After the test, there is usually a minimum waiting period before importation of anywhere from 3 weeks to 6 months.
    • There's always the possibility your pet fails the test - though this is unlikely if they have a good vaccination history.
Your veterinarian likely runs few, if any, FAVN tests; look like a genius and tell them they can send the blood to Kansas State University for testing. Likewise, if there are any unusual vaccines, treatments, or forms required your veterinarian may need a significant heads-up period to get what you need, or may need to send you to another vet. Hardly anyone stocks coronavirus vaccine, for instance.

If you've read all this and you still want to travel internationally with your pet...I admire your fortitude. You either really love Muffy, or you're crazy. Probably a little of both. But with preparation and planning, it is manageable.

Quick Tips for Pet Travel

Maybe you're headed on a big cross-country road trip. Maybe it's just a weekend with the in-laws a few hours away. Whatever the occasion, traveling with pets can be fun, exciting....and stressful. Poorly planned, it might even be dangerous. Today's article covers several easy tips to lower the stress level and keep things safe, so you can focus on relaxing and having a good time together.

Bear in mind this just refers to domestic travel by car; airlines and international travel are different beasts that will be covered in future articles.
  1. Bring plenty of extra food / medications: This is an obvious one...so it should be no surprise it's the most common one folks forget. Imagine running out of food, having to substitute something else, and triggering a nice bout of diarrhea. While driving. In your car.

  2. Seatbelts / carriers:  I'm not going to lie - my dog usually rides shotgun, unrestrained. He's also been dumped forcefully into the floor when I've had to slam the brakes. That wouldn't happen if I was smart enough to practice what I preach and get a pet seatbelt. Excited pets bouncing around the cabin isn't conducive to safe driving, either.

  3. Windows up: I once witnessed a Yorkie jump out of the car window as it drove by the vet clinic I was working at. Good timing, I guess - but it nearly killed him.

  4. LEASHES!: Never let your dog (or cat, or iguana) off leash in an unfamiliar place. I don't care how much you know/trust them - the unfamiliar sights, sounds, and smells could provide the unexpected surprise that leaves you spending the day searching for them, or worse.

  5. Dealing with anxiety and car-sickness: Pheremone collars (DAP or Feliway) can help many pets with mild travel anxiety. For motion sickness or more significant anxiety, talk to your vet about Benadryl and other options.

  6. Current flea & tick prevention: Make sure your pet's flea prevention will cover the duration of the trip; no one wants to finish off a vacation with a bunch of nasty new house guests. Do this even if you don't normally use a flea preventative - trust me. 

  7. Microchips: Make sure your pet's microchip is registered to your current address. If they don't have a microchip consider getting one
Here are a few more things you may want to ring your veterinarian's office for:
  1. Get a record or certificate of all vaccinations (and make sure they are up-to-date): Most hotels require up-to-date rabies vaccination at a minimum. Tell them where you are going, and ask if there are any other vaccines they'd recommend. These may include Bordetella, Leptospirosis, lyme disease, or others.

  2. If your pet has any major medical history - chronic diseases under treatment or past major surgeries - ask for a copy of the medical record to take with you. Hopefully your pet won't need veterinary care during the trip, but if they do that record may be invaluable.

  3. Ask your veterinarian about an official health certificate: may be required to enter certain states or to stay at some hotels, and all airlines require them. Your veterinarian can provide one after a thorough physical exam - which is itself valuable, since more than once I've picked up problems owners weren't aware of that might make travel a bad idea. Health certificates may only be good for a limited time (10 days for airlines), so set your appointment appropriately.
