We've had our dog for 6 months, he's about 20 months old. Super furry doodle. On our vet's recommendation, we've been giving him the (expensive!) flea and tick monthly oral dose of Nexgard. It's supposed to prevent/deter ticks and fleas, seemed like a good investment. So far, so good. Today we took him on a hike and while I was de-burring him, found two ticks in his ears that had clearly been there a few hours (slightly engorged). Removed them and flushed them immediately. We hike quite regularly and don't want to expose ourselves to ticks through the dog. What do you do for tick and flea prevention, and is it effective? I'm guessing I should do more to protect the kids too! Would love any suggestions - thanks.
