Looking for some feedback, PM's welcomed. I used frontline for years and never felt that I was really getting great protection in the WI Northwoods as my dogs would always have ticks on their necks. Two years ago I started on Certifect and have had great success, I really don't think that I have picked a tick off of any of my girls since I have been using it. My vet just told me this week that they will not be carrying Certifect anymore due to issues that dogs have been having and they are switching to a chewable, Nexgard.
1. What issues have been reported with Certifect? I haven't had any issues but would like to be aware
2. Any feedback on Nexgard?
