Life gets busy, and rabies due dates slip by. A lapse is common, but it's important to fix quickly, since the consequences can be serious.
Legal and practical consequences
- Fines or license problems: many places require current vaccination, and you may face penalties
- Refused services: boarding, grooming, daycare and travel often require proof of a current vaccine
- Delays in travel: an expired certificate can stop a trip or require a new health certificate
If your pet bites someone or is exposed
If a pet bites a person, local health authorities typically require a quarantine period, and rules can be stricter for pets without current vaccination. If your pet is exposed to a possible rabid animal, an overdue pet may face a stricter response than a pet with a current vaccine. In some cases, quarantine can last months. Rules vary by location, so ask your health department or vet.
Why vaccination matters
Rabies is almost always fatal once symptoms start, and it can spread to people. A current vaccine protects your pet and your family.
What to do if it has lapsed
- Call your vet promptly. Don't wait for the next annual visit
- Ask how the lapse is handled. Your vet will assess prior vaccination records, the vaccine label and local public-health rules before giving a booster. Do not assume a lapse always means restarting a series or that an overdue pet meets travel rules.
- Get an updated certificate and save it right away
- Check local rules for waiting periods and license updates
To book a booster, find a nearby veterinarian.
Prevent it from happening again
Set two reminders, at 60 and 30 days before expiration, and keep your certificate in your Waggle Vault.
