There is a longstanding debate amongst the pet parents about which one’s a better type of flea and tick treatment– Oral or Topical. Some of them are more inclined towards topical while some are strictly advocating Oral treatments and there are some more people who say that they go with the type of treatment that suits their pets.

And because, of these varied opinions and consumer choices, big brands are also constantly re-inventing and trying to come up with both oral and topical flea and tick preventives to increase their horizon in the market. One of those giant brands is the Merck Group. Merck Group has already changed the game by successfully introducing 3 months flea pills called Bravecto in the market. Bravecto initially was launched as a chewable for dogs in 2014 but to broaden its market reach, Merck also launched Bravecto spot –on for dogs and cats in 2016.

Now, after the launch of bravecto spot-on, there are different opinions about the efficacy of bravecto chewable or spot-on because one is oral and the other is a topical form of treatment. So, just to add to the ongoing debate here is detailed information about the differences and similarities between Bravecto chewable and Bravecto spot-on.
