I'm trying to make a decision on whether or not we should get Tucker a Lymes disease vaccine. We don't use any sort of flea/tick preventative. When we had to because he got fleas he ended up acting very lethargic for a week and didn't eat for two days so we'd like to not use it again. We live in Massachusetts which has like the fourth highest incidence of Lymes in people in the US. Last year we found two ticks on him, only one deer tick, and both were found on the same day that he got them (one hadn't even bit him yet, the one that had bit him was not engorged at all and both were found after he came home from the park). But Lymes disease is kind of scary and I don't want it to be my fault if he gets it (since my parents allow me to make the decisions regarding things like his vaccines, they'd just do whatever the vets tells them). Over the summer we got out fairly often...park once a week, walks in the woods a few times a week, lots of time in the yard and going on regular walks through the neighborhood. So opinions? What are the risks of the vaccine? How often is it needed? Do you think Tucker's at a high risk for getting the disease?
