What days do they have dog vaccinations at petco and what time?

2-4pm they are quick as well.

There is a vaccination clinic every Saturday afternoon at the Colonie location. I believe it starts at 2 but if you Google Vetco, you can get information on this clinic and others that are in or around Albany

Check the vetco website they have the schedules and package pricing on there https://www.vetcoclinics.com/services-and-clinics/clinic-locations-and-schedules-ip/
