A simple google search of Bravecto (or any medicine, really) will bring up the scientific reports, trials and fda/cvm information. This is all honest, scientific information. Bravecto is extremely safe. Reading through this Freedom of Information Summary, you can read about all of the studies done and any and all adverse reactions.
For those who think oral is more dangerous than topical – topical soaks transdermally directly into the bloodstream. It also has the potential to be spread between animals, as well as humans. Some require placement in spots along the back. If the dog then licks around his back where he was treated, he has then taken the drug transdermally, as well orally. I, for one, would rather know exactly the dose my dog is getting, without the fear of my children getting it on them by touching the dog, or touching the dogs bedding, etc.
For those with dogs in the 75-80 pound range that claim this doesn’t work, your dog is at the very top of the dosage weight. It is possible that the dose is just not strong enough for your dog and you should speak to your vet about using the next size up, which in this case would be for 88lbs. In most cases, this is perfectly acceptable.
All flea and tick treatments are pesticides. No matter how they are administered. If you are against chemicals completely, that is one thing. But, if you are against only particular chemicals, I would say do some research.
