When does a puppy get vaccinated?

Core vaccines start at 6-8 weeks (DHPP first dose), continue at 10-12 weeks (DHPP second dose), and complete at 14-16 weeks (DHPP third dose plus Rabies). A booster is given at 12-16 months, then every 1-3 years for adult dogs depending on the vaccine and local regulations.

Can I take my puppy outside before vaccinations are complete?

Low-risk socialization is both safe and necessary before full vaccination. The AVSAB position statement explicitly states that socialization should not wait for the full vaccine series because the socialization window closes before vaccines are complete. Avoid dog parks, pet store floors, and contact with unknown dogs. Carry your puppy in busy areas.

What is the DHPP vaccine?

DHPP is a combination vaccine covering four diseases: Distemper (severe neurological and respiratory disease), Hepatitis (adenovirus affecting the liver), Parvovirus (highly contagious and often fatal intestinal disease), and Parainfluenza (component of kennel cough). All four are core vaccines recommended for every puppy.

Is Rabies vaccination required by law?

In most countries and US states, yes. Rabies vaccination is legally required and is the only vaccine with a specific legal mandate in most jurisdictions. Your vet will provide a Rabies certificate after vaccination, which is needed for licensing, travel, and boarding.

What side effects should I expect after vaccination?

Mild lethargy and soreness at the injection site for 24-48 hours is completely normal. A small lump at the injection site may persist for several weeks. Contact your vet immediately if you see facial swelling, hives, repeated vomiting, or difficulty breathing — these are signs of an allergic reaction.

What is the difference between core and non-core vaccines?

Core vaccines are recommended for every puppy regardless of lifestyle: DHPP and Rabies. Non-core vaccines are recommended based on risk factors: Bordetella (kennel cough) for dogs in daycares or grooming; Leptospirosis for dogs with wildlife or water exposure; Lyme for tick-endemic areas; Canine Influenza for social dogs.

My puppy had all their shots. Are they now fully protected?

Protection builds gradually over the series. After the third DHPP dose at 14-16 weeks, immunity is considered solid. Maternal antibodies from the mother can interfere with early doses, which is why the series is necessary rather than a single shot. Annual or triennial boosters maintain the protection.
