you had some other questions in the thread that was locked. As for the Revolution – my vet did his own testing on it with the huntclub dogs he cares for – & thinks it is wonderful. It is also used to treat one form of mange & ear mites you know. Even when I lived in the NE I kept my dogs on HW year round as I have seen mosquitoes in the winter too. I am not familiar with the other product you mentioned & couldn’t find it on the internet, but since cortisone is a steroid, long term use could be a problem for the liver & kidneys depending on the amount per dosage. If I missed anything please let me know.
