I'm thinking about switching the dogs to something else. They're on Sentinel right now but our vet said heartworm isn't a problem here and I've been reading up on some articles about long term effects from heartworm meds. I'm going to keep them on Sentinel for the rest of the summer and then take them off for the rest of the year. I'd like to keep them on some type of flea preventative though. I can't imagine having to deal with fleas on these two.
How does frontline work? I heard it's applied between the dog's shoulder blades. Is it really hard to apply right? How effective has it been for your dogs?
Also, does anyone else know of flea preventatives that are not given orally?
