I'm taking my dogs in for an exam and getting this today. Its made by frontline and I trust them. A couple vets have said that they are offering a decent rebate if one buys nexguard and heartguard together. Most vets haven't got it yet and the ones that do have it have a very limited supply and its on back order. They also say that doggie dermatologists have been using it for a while and its very popular. I like that its safe enough that if they eat 10 it won't hurt them, just like heartguard plus. They also said that the American Dog Tick is the hardest tick to control and they are pretty confident that all other ticks would be covered to.
