Health & WellnessIs it okay to switch my new adopted dog from Sentinel to Trifexis?
Hi, thanks for using Petco Pet Education Center, formerly Petcoach!
Switching to Trifexis is fine. Just be aware that Trifexis doesn't get ticks (neither does Sentinel, it is just heartworm, GI parasites and sterilized female fleas).
I hope this helps!
