Puppy Vaccination Schedule for Welsh Terriers
A first-year immunity timeline for the small-breed Welsh Terrier (19-21 lb adult, typical lifespan 12-15 years), with DA2PP/DHPP, rabies, and lifestyle vaccines dated so no booster is guessed at a border, boarding desk, or ER.
Clinical context
Why this stage is different for Welsh Terriers
Welsh Terrier puppies finish core immunization later than many owners expect. Because this is a small terrier dog - with primary lens luxation and allergies already on the watch list - every vaccine lot number, clinic, and next-due date belongs in one vault. Socialization can start after the first core vaccine, but public dog-park density should wait until the series is complete. Store the certificate images beside weight and stool notes so titer or travel paperwork does not stall.

Dated protocol
First-year immunization timeline
6-8 wk
First core vaccine
Start DA2PP/DHPP. Weigh the Welsh Terrier puppy; toy/small dogs can be under-dosed if the clinic uses an outdated weight.
10-12 wk
Second core + fecal
Repeat core vaccine. Deworming and fecal antigen reduce “failure to thrive” that owners mistake for food issues.
14-16 wk
Third core + rabies
Complete the core series; rabies timing follows local ordinance.
20-26 wk
Lifestyle boosters
Add Bordetella/lepto/influenza if daycare, travel, or standing water is in this household’s pattern.
12 mo
First annual review
Confirm which antigens move to 1-year vs 3-year labels. Archive the full packet before the puppy record is “lost” at a new clinic.

How to keep the schedule legally useful
- Photograph every Welsh Terrier vaccine certificate the day it is issued - glare-free, full margins.
- Record lot number, route (SQ vs IN), and any antihistamine pre-med in the same timestamped note.
- If a dose is delayed by illness, log the reason so the series is not accidentally restarted.
- Flag primary lens luxation and allergies so the veterinarian can adjust handling (airway, joints, heat) on vaccine day.
- Export a PDF before boarding, relocation, or a new specialist visit.
Bowl notes
Vaccine-day feeding notes
Small breeds need calorie-dense growth food without free-feeding that pads the ribcage.
A light meal 2-3 hours before vaccination reduces nausea; do not fast a toy-breed puppy overnight.
If an elimination diet is already underway, do not change proteins on vaccine day - you will not know what caused a flare.

Puppy Vaccination Schedule for Welsh Terriers - common questions
Core immunization is typically complete 2 weeks after the last DA2PP/DHPP dose around 16 weeks of age. Rabies timing is set by local law. Until then, structured socialization is still important - choose vaccinated-adult play, not high-density dog parks.
Titers can document antibody for some core viruses in adult dogs. Puppies still need the initial series. Store titer lab PDFs next to the vaccine history so a boarding facility or border official can read both.
