https://community.qvc.com/t5/Community-Chat/Certifect/m-p/156704#M68805 <P>Has anyone tried this new flea and tick medicine? The vet we go to has discontinued Frontline Plus in favor of Certifect. We have a pug with acquired liver shunts and I am hestitant to use anything that will possibly compromise him more than I need to. My feelings is that Certifect has not been on the market long enough, and yes, flea and tick preventative is necessary.</P> Wed, 18 Jan 2012 14:20:36 GMT sue52 2012-01-18T14:20:36Z https://community.qvc.com/t5/Community-Chat/Certifect/m-p/156704#M68805 <P>Has anyone tried this new flea and tick medicine?
