I recently rescued an Aussie from a shelter who was injured and needed a few stitches. Because of this I was unable to give him a flea bath for several weeks. He was covered in fleas and ticks (not to mention internal parasites) and the topicals didn’t even make a dent. My vet prescribed a dose of Bravecto and it worked very well at killing the parasites quickly. My dog, however, was extremely listless for 24 hours before rebounding. I’m not sure if it was the medication or the culmination of all the trauma/surgery/exhaustion but I figured that Bravecto was too strong for him on a regular basis. As we do not have a tick problem in my area I switched him to Comfortis for flea control, as my other two dogs (another Aussie and a corgi) have been taking it for years. Fortunately, none of my dogs have had any issues with it.
