How a Vaccination Schedule Works

A vaccination schedule is not one appointment but several that build on each other. The reason is simple: a young animal gradually loses the protection it got from its mother, and its own immunity has to take over.

Why more than one dose

The first dose introduces immunity; the boosters consolidate it. A single dose often does not give the protection people expect, which is why keeping to the intervals can matter more than which vaccine was used.

If the schedule slips

A late dose does not always mean starting over, but that decision is made by looking at the records. If you have a previous vaccination card or notes, bring them to the appointment.

After a vaccination

Mild drowsiness and a brief dip in appetite on the first day are common. If you notice anything beyond that — facial swelling, vomiting, changed breathing, a lump at the injection site that does not settle — do not wait. Call.

⚠️ This page gives general information. Which vaccine is given and when depends on the animal's age, history and living conditions, and is decided at the examination.
