Thanks for that info V&F. I am not keen on vaccinating at all and never used to do it. Soms of my dogs had a full puppy course, some might have had one puppy vax but none of them ever had any booster shots. Pippi is our first dog to have been vaccinated as per the "right" way.
I believe dogs build up their own immunity if allowed
That's a really good point about 3 years of poison in one shot. For some reason, I though it would be a diff vax and never really looked a it like that so I think we will stick with the yearly for now (though, Barney was due last month and hasn't been in yet, I think I will wait til Pippi is due in Aug/Sept and take them both at once for ease)
