Take the fecal parasite exam, that's a $30 charge just to see if your dog has worms. My dogs have both been wormed. Yet my Vet wants to do this exam every year. They also feel it's necessary to test for Lyme Disease every year. I don't let them. This morning my Vet arrived prepared to vaccinate Lilly for Lyme disease. Today, when I said "no," my Vet became a little nonplussed. When I pointed out that Lyme Disease in dogs can be cured with simple antibiotics, she fumbled. "Not always," she said, "if you wait too long and it's well advanced antibiotics may not work." Then I added "and 90% of all dogs infected with Lyme Disease never develop symptoms." And her retort was "but people are finding ticks everyday. And deer ticks are very tiny." You will notice she did not correct me, nor even deny what I said because most people just nod and say "yes."
