I am SO sorry you and your Puppers are having to go through this. I know everything's supposed to have a purpose ~ but I'm yet to hear one good reason for ticks!
My Pups went in for their Wellness Checks today. I did the Hw/Lymes/Ehrlichia Canis/Anaplasma (I do it twice a year) and brought home more Frontline Plus too. I ran the idea of the Play Dead Herbal Collars by my Vet & he agreed it to be a good extra precaution. I just sent in my order to Petfooddiner.
Stupid Lyme Disease!!!!!
Our best precautions are not always enough. Maybe when Lily's Momma gets back home she can give you some good advice. The only experience I have had was with one of my horses.
Hang in there! It's bound to get better.
