I use Sentinel for heartworm, flea control, year round(Florida). I have used it for 4 dogs now without issues. It does not do anything for ticks though. There was a big tick outbreak here 2 years ago when I first got Shadow and found several walking on him,not attached. I freaked out. First I tried a topical and it did nothing. My vet suggested a pill, I used it for 4 months and thankfully the ticks thing is over but I am always looking.
He has not had Lepto, at almost 3yrs., much to my vet's dismay. My breeder doesn't do it either.
I think that it depends on your area and lifestyle.
