Whichever, we've had really good results with using both but only use the Comfortis during the peak flea season. Summer kinda snuck up on me this year and I noticed a flea on one of the Aussies the other day which reminded me that the Sentinel was probably not doing the trick so well since it was the end of the month. I need to go get some Comfortis before the 15th. |
I have noticed about the end on the third week on comfortis Addy sometimes starts to get fleas.
