I have been using this on my two dogs and recommend it. My guys were having issues (reaction) to the topicals so I like this and feelings safe. I hope also there been no reaction to the Nexgard.

Something else I found that works is Vaughns Furfresh shampoo. If my guys pick up a flea this stuff takes care of it. It also works with ticks too. I swear by it. http://furfresh.com/

Hope this helps.
