Puppy owners

So how do you all vaccinate? My puppy needs his second set of shots. I planned to use Spectra 9. But I also wanted to do bordetella. Spectra K3 has bordetella but it also contains adenovirus and parainfluenza, and I don't want to double dose on those last two which are included in Spectra 9. Can anybody recommend a brand or place to get the bordetella without any add-ons? Or does anyone care to share how they go about their puppy shots? Thanks in advance!
