The Lyme disease vaccine for dogs costs between $30 and $65 per dose, with most dogs needing two initial doses plus an annual booster. That puts your first-year cost at roughly $60 to $130 for the initial series, then $30 to $65 each year after that. Prices vary by clinic, region, and whether your vet charges a separate exam fee for the visit.
What the Full Vaccination Schedule Costs
The initial series requires two doses given two to four weeks apart. Your dog can start as early as eight weeks old. After that first pair of shots, a single booster is given one year later, then once annually for as long as the risk of tick exposure continues. So in a typical first year, you’re paying for two doses plus the office visits. In year two and beyond, it’s one dose per year.
Some clinics bundle the vaccine into a wellness visit, which can reduce the overall cost. Others charge a $40 to $60 exam fee on top of each dose. If cost is a concern, ask whether your vet offers vaccine-only appointments or wellness packages that include Lyme along with other routine shots.
How It Compares to Treating Lyme Disease
Treating a dog that actually contracts Lyme disease typically runs $200 to $800, depending on how severe the infection is. That doesn’t account for the diagnostic testing to confirm the disease, potential follow-up visits, or complications like kidney damage that can drive costs much higher. Two vaccine doses at $30 to $65 each look like a straightforward bargain for dogs with real tick exposure.
Does Your Dog Actually Need It?
Lyme is classified as a “noncore” vaccine by the American Animal Hospital Association, meaning it’s not recommended for every dog. The decision depends on where you live, how your dog spends time outdoors, and whether you travel to tick-heavy areas.
The highest-risk regions are the Upper Midwest and Northeast, where blacklegged tick populations are well established. But the risk zone is expanding. Indiana, Illinois, Michigan, and Ohio are increasingly connecting those two hotspots, and Lyme is pushing southward into eastern Tennessee and northern North Carolina. North Dakota, northeastern South Dakota, and southeastern Iowa are also seeing higher-than-normal risk. The Companion Animal Parasite Council forecasts these trends continuing into 2025 and beyond.
Dogs that hike, hunt, camp, or spend time in tall grass, wooded areas, or marshes face the most exposure. If your dog mostly stays on sidewalks in a low-risk region, the vaccine may not be worth the cost. The CDC’s map of reported human Lyme cases is a useful proxy for canine risk in your area.
How the Vaccine Works
Two main types of canine Lyme vaccine exist: bacterin vaccines and subunit vaccines. They work differently at the molecular level, but the practical distinction matters.
Bacterin vaccines contain whole killed bacteria, exposing your dog’s immune system to over a thousand different bacterial proteins. Subunit vaccines are more targeted, using one or two specific proteins from the Lyme-causing bacterium. The more advanced subunit vaccines target the bacterium at two stages of its life cycle: inside the tick before it enters the dog, and during early infection in the dog’s body. That dual approach gives two independent layers of protection.
One newer subunit vaccine has been shown to prevent actual infection in dogs, not just reduce symptoms. Your vet can tell you which formulation they carry and why they prefer it.
Side Effects Are Typically Mild
The most common reactions after any canine vaccine, including Lyme, are minor and short-lived. You may notice a small firm lump at the injection site, mild swelling or tenderness, reduced energy, loss of appetite, or a low-grade fever. These generally resolve within a day or two without treatment.
Serious allergic reactions are rare but possible with any vaccine. If your dog develops facial swelling, difficulty breathing, or persistent vomiting after a shot, that warrants an immediate vet visit.
The Vaccine Isn’t a Standalone Strategy
Even vaccinated dogs benefit from tick prevention. The vaccine doesn’t repel or kill ticks, so your dog can still carry them into your home and still be exposed to other tick-borne diseases the Lyme vaccine doesn’t cover. Pairing the vaccine with a tick preventive (topical, oral, or collar) and doing tick checks after outdoor adventures gives the most complete protection. If you’re hiking with your dog, sticking to cleared trails and avoiding overhanging branches reduces the chance of picking up ticks in the first place.
