Bobby dog, thanks so much for the extensive response and your experience.
Bruno seemed ok on Trifexis, but on Sentinel now, he is a tad bit itchier. Now… I am not sure, if it is because he’s getting a tiny bit of grain in his food (although he’s had it before, HHE Original), or because of Sentinel. It is not too much itchiness, so I’m not very worried.

I still wonder which is better – topical chemicals for fleas or internal ones (through the pills)?

I saw that Cedarcide Best Yet only has 2 ingredients, so I may actually try that as well. What is considered flea season? The warm months? That’s like 3/4 of the year here in GA, lol. But I have only seen one flea on Bruno so far since we’ve had him since July of last year. So Trifexis did work well on him… Hope Sentinel does too!
