Hi I have a 9 month old Sheltie pup who is currently on Frontline for her flea and tick medication. I was looking through a magazine and noticed that K9 Advantix does the same thing as frontline, but is also good for repelling/killing mosquitoes. Is the K9 Advantix ok for use on our Shelties? I would really like to switch her to it next month as I live in a area that is HIGHLY concentrated with mosquitoes in the summer months. I currently have her on Interceptor for heartworm so I am not very concerned with her getting that, but I know how bad the skeeters bother me so I can only imagine how she feels while she is out running around. Thanks!
