Delaware pet vaccination records — what to keep ready

Delaware's rabies law covers both dogs and cats

Delaware law (Title 3, Chapter 79, §7903) requires rabies vaccination for all dogs and cats four months of age and older. This is enforced at the municipal level through licensing — New Castle County, Kent County, and Sussex County all require proof of current rabies vaccination for pet licensing. Unlike some states that only mandate rabies for dogs, Delaware includes cats in the requirement, which matters because cats are the domestic animal most frequently reported rabid in the eastern United States.

Raccoon rabies in Delaware: the mid-Atlantic corridor

Delaware sits within the mid-Atlantic raccoon rabies corridor, one of the most active rabies zones in the country. The raccoon variant of rabies has been established in the eastern seaboard since the 1970s and Delaware reports positive wildlife cases each year. The Delaware Division of Public Health monitors rabies and posts animal rabies case counts by county. Raccoons, skunks, and bats are the primary wildlife reservoirs. Any pet encounter with a raccoon, skunk, fox, or bat — even without a visible bite — should be reported to animal control and your vet immediately. (Delaware Division of Public Health — Rabies Program, accessed September 5, 2026)

This is not theoretical risk. Delaware animal control agencies receive rabies exposure reports regularly, and the state maintains a wildlife rabies oral vaccination bait distribution program in partnership with USDA Wildlife Services to control raccoon rabies spread.

Lyme disease in Delaware: rising tick exposure

Delaware is endemic for Lyme disease. The Delaware Division of Public Health consistently reports the state among the highest per-capita Lyme disease incidence rates in the country. The primary vector is the blacklegged tick (Ixodes scapularis), which is present throughout all three Delaware counties but most concentrated in the wooded areas of northern New Castle County and parts of Sussex County. Dogs are highly susceptible to Borrelia burgdorferi infection, and Lyme nephritis (kidney complications from Lyme) can be fatal in some breeds, including Labrador Retrievers, Golden Retrievers, and Shetland Sheepdogs. (Delaware Division of Public Health — Lyme Disease, accessed September 5, 2026)

The Lyme vaccine for dogs is available and recommended by many Delaware veterinarians for dogs with outdoor exposure. It is not legally required, but most Delaware vets include it in their core wellness discussion. Keep Lyme vaccination records alongside tick prevention product records — the combination matters for full protection.

Leptospirosis: Delaware's water and farm connection

Delaware's mix of agricultural land, coastal marshes, and suburban development creates exposure pathways for leptospirosis. The bacteria shed through wildlife urine (raccoons, rats, deer, farm animals) and survive in standing water and wet soil. Dogs that walk through puddles after rain, play in creeks, or visit farmland areas in Kent and Sussex County are at increased risk. The leptospirosis vaccine is not state-required but is widely recommended by Delaware veterinarians, especially for dogs in rural or suburban settings with wildlife or livestock contact.

Heartworm in Delaware

Delaware's humid summers and extensive marshland (particularly in the inland bays of Sussex County and the Christina River watershed) support robust mosquito populations from April through November. The Companion Animal Parasite Council (CAPC) considers Delaware a moderate-to-high heartworm risk state. Year-round prevention is recommended by most Delaware veterinarians, even though transmission drops in winter months, because the consequences of missing a dose during peak season are severe. Keep heartworm test results and prevention purchase dates in your records. (CAPC — Companion Animal Parasite Council, accessed September 5, 2026)

How Voocie keeps your Delaware pet's records organized

Give your vet your pet's @voocie.com email address. After every visit — vaccines, bloodwork, treatment — they email the records to that address. Voocie's AI reads the document, extracts the vaccination dates, medications, and lab values, and adds them to your pet's timeline automatically. When your dog needs their bordetella updated for boarding, you check the timeline. When the ER vet at VCA Newark needs the full history at midnight, you share it by link.
