Hi there. Yes, Bravecto is an excellent product - it's extremely safe, and very effective. It's the main flea medication that we use at my clinics, and what I am currently using for my own three dogs. In terms of side effects, we occasionally have clients report some mild lethargy or stomach upset for a day or two after giving it, but most dogs have no side effects at all. Nexgard or Credelio would also be reasonable choices.

    Bravecto is a highly effective and very safe medication to prevent both fleas and ticks. Any medication has a list of published possible side effects because drug manufacturers must report all side effects noted during their clinical trials of medications, whether or not they are related to the medication being tested or not. I often recommend Bravecto and have only seen one patient vomit once after taking the medication. Trust your vet's knowledge and education over reviews online or blogs with no medical credibility! :-) I find that Bravecto is both safer and more effect than flea collars. I hope this helps!
