Is it safe to switch from Frontline to K9 Advantix II?
My dog is due for his monthly treatment also same question for our other dog (sister) Bree female Bichon same age weighs 12
Our Vet Says:
There won’t be a problem if you change the
products but you need to leave 4 weeks between applications. If you need
protection for fleas only you can swap Frontline to Advantage II.
