I actually don't care much for sprays, in general - there are much better options for flea/tick control in dogs. My favorites are oral medications like Nexgard or Bravecto, but a Seresto collar or topical medication like K9 Advantix can also work well. If you really want to use a spray, I would suggest Frontline spray - it isn't always terribly effective for fleas, in my experience, but works well for ticks and should be safe. Many of the other over-the-counter sprays contain very harsh chemicals that can be dangerous, so I don't usually recommend them unless you have no other choices.

    Yes, I would use better drops for your dogs. The cheap ones don't work as well because the active ingredients are not as strong as the ones you can get from the vet. I don't recommend using Frontline because I personally have seen resistance to it, as have colleagues of mine. I recommend using Advantage or Revolution, but as an oral flea treatment, NexGard is good, as well as Comfortis and Trifexis.

    If you want an over-the-counter product, go with Frontline but there are issues with resistance to this product. Otherwise I recommend to call your veterinarian and discuss one of the top products such as Simparica or Nexgard. I hope this helps and enjoy your trip.
