Is your dog's flea medication toxic? - SheKnows
There are times when dogs and cats can take the same medication, under a vet's supervision, to resolve an issue. This is definitely not one of them. Not only are some flea and tick medications specifically formulated to be effective for dogs (or vice versa); there are certain ingredients that can actually be harmful, even deadly, to cats. "Cats should never be given products designed for use on dogs," says Dr. Jennifer Kvamme, DVM, "nor should you use your cat products on your dog." Always read flea and tick control products labels carefully and only use as directed. If you have any doubts, ask your veterinarian.
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.

Not all of the oral medications work to kill adult fleas. Medications that contain lufenuron, for example, work by preventing adult fleas from producing eggs, stopping the so the population of fleas cannot continue to grow. Other common ingredients seen in oral medications include spinosad, nitenpyram, and milbemycin oxime. Nitenpyram is an ingredient that can be given daily if necessary, as it kills fleas within an hour and does not stay in the pet’s bloodstream for an entire month. For this reason, it is safe to use in pregnant and nursing cats or dogs.
