| Frontline usually works well for me but I do know that one year (the only year we've ever had fleas) my vet said they had a huge problem with fleas seamingly being immune to it the one year. I can't remember what we ended up using but I remember it was a combination. You may want to contact your vet. Hopefully the Frontline will keep them at bay for us this year. I had a nightmare about fleas the other night and woke up fraking out looking for them all over all my animals and myself. |
