i have my dog vaccinated for Lyme disease and boosters every time my vet. says to. so can my dog still get Lyme disease? i haven’t found any ticks on her lately and we treat her with frontline monthly.

when he was 4, my parents found a tick on my head halfway into the scalp, but I never had Lyme disease, why? A blood test can tell if reg or not? or is special stage you must take to know you're infected with the disease?
