Is Advantix II safe for my dog? Worried about tick medicine risks.

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 75 lbs

Is Advantix II o.k. to use for ticks on dogs? I am so afraid of giving them something that will hurt them but next to the woods here there tend to be alot of ticks and it scares me. I have considered the pet pills that are given by the vet...but again... I am really afraid if once they are taken and the dog may have a bad effect.... then what? I want to protect them but there are alot of scare factors out there.

Hello. There are a lot of really good flea & tick products out there, & for everyone one of them, you can find an untrue horror story online. Advantix ll has been around for over 10 years & if there were significant problems with this, it would be long gone by now. The oral products Bravecto & Nexguard, are also very, very good. The problem with the orals is that a similar product called Simparica, was associated in a slight increase in tremors or seizures in some dogs. But this has really not been the case with either Bravecto or Nexguard. Tick disease can be very serious, costly & dangerous. You have to weigh the very small chance of a reaction associated with one of the flea/tick products with the real possibility of a serious tick borne disease. I would rather not have to deal with nasty ticks on my pets or in my home. I regularly use Bravecto on some of my pets & the Seresto collars on others & have been very happy. Your vet, who is more familiar with your dogs overall health is an excellent source of what might be best for everyone. Hope this helps & that is a great picture of your guys.
