I ordered a Seresto collar and my dog got fleas the day before it came in. I applied Frontline Plus Flea and Tick on her to get rid of the problem asap. Can I still put the collar on when it arrives or should I wait until the 30 days is over?
We recommend waiting for 30 days before you put the Seresto Dog Flea and Tick Collar
