I know a lot of people let their dogs sleep in the bed and on the sofa but keep in mind if you use the topical monthly preventative you probably are getting it on you. May not be as much of a dose for adults but may be for children who may also have the genetic potential to have an adverse effect. Genetic susceptibility along with a environmental toxin or virus, etc could be the cause of syndromes like autism. There is so much we still don’t know. Just something to consider when using tick preventatives.
