What Every Pet Parent Should Know About Vaccines
Dr. Olson is pretty clear-cut in his view that vaccines save lives. After several years of working in emergency rooms in Dallas, he's seen more avoidable illness cases than he cares to count. Cases that, in many instances, didn't have to happen.
Vaccines are one of the most powerful tools we have to protect our pets, and we want every Dallas family to feel confident about where their pet stands. These are preventable diseases, and prevention starts with a conversation.
The Core Vaccines Every Pet Needs
The World Small Animal Veterinary Association recommends three core vaccines for all dogs, regardless of lifestyle: Rabies, DHPP, and Leptospirosis. They're the foundation of preventive care, and each one earns its place.
Rabies is legally required in Texas for both dogs and cats because skunks, bats, raccoons, and feral dogs and cats throughout our area carry it regularly. Rabies is 100% fatal once symptoms appear, and the only reason it feels rare in the United States is that we vaccinate so consistently. In countries where the vaccine is less accessible, like India, rabies spreads from dogs to people and kills more than 59,000 people every year. A high-rise poodle is not exempt because wildlife is closer than you might think: bats fly, mice crawl, and our pets are going to the bathroom on the same grass the squirrels are.
Leptospirosis surprises a lot of pet owners. Most assume it requires some kind of direct wildlife encounter. “Lepto” is spread through the urine of small mammals: mice, rats, squirrels, and raccoons. Those animals are in just about every yard in Dallas, no matter how tall your fence is or how manicured your garden. This bacterial disease can cause damage to the liver and kidneys. It is treated easily enough by a common antibiotic, but by the time a pet is sick, the antibiotic can’t reverse the damage.
DHPP covers Distemper, Hepatitis, Parvovirus, and Parainfluenza in one vaccine. Distemper alone is airborne and carried by coyotes and feral animals throughout the area. It doesn't require direct contact to reach your pet and can cause serious neurologic issues. In Dr. Olson’s view, “Parvo” is one of the most devastating diseases he saw during his time working in the ER, and it is entirely preventable.
Lifestyle-Dependant Vaccines
Vaccines for Canine Influenza, Bordetella, Rattlesnake venom, and Lyme disease exist, but they are recommended only for some pets.
Influenza and Bordetella are some of the primary components of CIRDC (Canine Respiratory Disease Complex) commonly known as “kennel cough”. Think of it like the common cold in people: very contagious and for most animals, unlikely to be life-threatening. If your dog is ever within six feet of another dog, gets groomed, goes to a boarding facility, visits a dog park, or plays with a friend's dog, these shots are worth a conversation. During a severe influenza outbreak in the early 2020s, Dr. Olson lost multiple patients who were hospitalized with this illness — it made a lasting impression.
Lyme disease is far less common in Texas than in the Northeastern United States, and Rattlesnake exposure is primarily a concern in the Western part of the state. For most Dallas pets, those two are pretty low-priority.
Options For the Vaccine-Hesitant
We understand that some pet parents have concerns about vaccines, and we take those concerns seriously. In recent years, hesitancy toward pet vaccines has grown alongside hesitancy toward human vaccines, and studies suggest that nearly 40% of dog owners have some concerns about vaccine safety. We want to address that directly:
Adverse reactions are genuinely rare. A large-scale study reviewing data from more than 4.6 million dogs found an adverse reaction rate of roughly 19 per 10,000 vaccinations (that’s .19%). Smaller breeds and younger dogs carry a slightly higher risk, which is why we space them out for puppies and use smaller vaccines for smaller dogs. The company we source vaccines from makes a newer line that are half the size of traditional vaccines for those smaller breeds. This company also covers the cost of treatment if a reaction does occur, which we find very reassuring and think you will too!
For pets that are current, Rabies and DHPP can be extended to a three-year schedule so you don’t have to bring them in for a shot each year. However, if your pet is late or overdue, they’ll have to return to annual until they're current again. Lepto is always annual to provide maximum protection. Pets should still be examined annually to make sure minor issues are identified while they are still small, like dental disease, lumps and bumps, and other various symptoms.
Vaccines work by letting the body practice making antibodies before the real infection. These antibodies can neutralize the threat before it has a chance to wreak havoc on the body. Titer testing quantifies the amount of antibody present in the pet’s bloodstream. We can run blood tests commonly called “titers” to measure your pet’s existing immunity and can help guide decisions before revaccinating. These antibodies are ready and waiting to fight diseases before the pet gets infected in the hopes of preventing or minimizing symptoms. That said, immunity is multi-faceted, and circulating antibody levels are only one part of how the body fights disease. And when it comes to Rabies specifically, an adequate titer does not satisfy the legal requirement in Texas. The vaccine is still required by law regardless of titer results. One of the many jobs of a veterinarian is to protect the public’s health, and vaccines are a big part of that endeavor to keep us all safe.
A Note on Life Stage
Vaccines matter at every age, but they are especially critical at the beginning and end of a pet's life. Puppies and kittens are building their immune systems from the ground up and need the full protection a proper vaccine series provides. Senior pets experience natural immune decline that makes them more vulnerable to these same diseases. Both of these groups deserve extra attention and consistency when it comes to veterinary care.
Keeping Your Pet Protected
If you have questions about your pet's vaccine history, want to talk through a conservative schedule, or are simply overdue for a visit, Dr. Olson is happy to work through it with you during an appointment. He can even come to you in our new mobile clinic. No waiting room or stressful car ride for your pets, just a straightforward conversation about keeping them healthy for the long haul. We even bring the treats!
