Your puppy’s first year, month by month
Month-by-month guides for new puppy owners: vaccines, socialization, training, spay or neuter timing, and a record for every vet visit.

Short versionThe first year goes fast. The big decisions are vaccines, socialization before 12 weeks, spay or neuter timing and building routines. This site walks through each one with sources and a record you can keep.

The three things that matter most in the first weeks
- Start the vaccine series with your vet. AAHA recommends at least 3 doses of the core combination vaccine between 6 and 16 weeks of age, 2 to 4 weeks apart.
- Socialize safely and early. The AVSAB says the first three months are the primary window and that classes can start as early as 7 to 8 weeks.
- Keep one record. Weights, deworming, vaccines, questions and odd moments, so every vet visit is easy.
A puppy question, answered for your puppy
Select your puppy and ask about vaccines, socializing or the first vet visit. The answer is built around their age and breed, with a schedule you can take to your vet.
