Just stay with frontline , since many dogs died from this shot ,including one of my puppy

And creating birth defects by bitches !!!
The doctor reaction maybe had a allergic reaction. It's bull s**t. The first shot is the one what creating the Lyme disease , and the follow up shot usually is fatal. By puppy's
So font be lazy put a nice mark in the calendar or the sticker for the frontline ,and don't believe everything to the doctor !!!!
I belong to many Yorkie clubs and I have lots of experience with yorkies so hear lots of sad story's with Lyme disease shot
