Hi T, alot of ladies from the dog park use Comfortis & swear by it, its used monthly….after apply for a couple of months the ladies said that they didnt have to re-apply some months as its was still working & the dogs still didn’t have any fleas…they just give the tablet now if they see a flea & the dog start scratching..they start giving Comfortis when spring starts then their dogs are flea free for the summer….1 lady said that she hasn’t needed to give any Comfortis for 6months & she has had no fleas….
Just be careful giving first dose, make sure you know your dogs weight & only give half the tablet with food in morning, if dogs shows no side effects, then give the other half of the tablet at night with their dinner..
Comfortis must be giving with food, as a few dogs have gotten real ill & some have died here in Austrailia when the drug first came out….
