Best flea med if your dog is allergic to flea bites!
Years ago I had a dog that was always on flea meds but she was chewing right at her tail and her feet. It was just awful. I tried everything. Changed her food, allergy meds, etc. then someone told me to try Comfortis - apparently even on flea meds if a dog gets one flea bite and is allergic she will scratch horribly and chew her feet. Put her on Comfortis and it stopped! Her hair all grew back. I'm a total believer in Comfortis!

Doesn't work on every dog apparently
Applied this 3 weeks ago. Dog still has adult fleas. No other pets, bedding sanitized. Did all the correct remedies. At nearly $20 per pill, and having to buy a pack of 6, I find myself a bit miffed. Product doesn't work.

Comfortis prevents flea infestations
From UndisclosedComments about Comfortis Chewable Tablets for Dogs 5-10 lbs or Cats 4.1-6 lbs, 6 Month SupplyLiving in Florida, we have fleas year round. Comfortis once a month prevents any flea infestation. I haven't seen a flea on any of our 3 dogs since we started them on comfortis a few years ago. I crush it up and mix with a little cooked hamburger and they gobble it up.-

i am interested in trying with my cats but want to know the size of the pill as they are difficult to "pill" and if it's a large pill i don't think it would work for them. thank you for your time.?
-
The size of the pill your cat would take depends on your cat's weight. If your cat is 12.1-24.0 pounds, each tablet would be about the size of a dime. If your cat is 6.1-12.0 pounds, the tablets are slightly smaller, and if it is 4.1-6.0 pounds, two tablets would be about the same size as a dime. If you have further questions or concerns or if you want further recommendations, please consult your cat's veterinarian.

When I bought my 6 pack of Comfortis, I ordered the ones for 10-20 pound dogs. She is now older and bigger - 25 pounds. Can I just give her 2 of the smaller pills??
-
The pills that you ordered contain 270mg of the active ingredient spinosad per tablet. The recommended dosage given your dog's size is 560mg of spinosad. Two of the tablets you have would approach the recommended dose of 560mg but would be just below at 540mg. It is best to consult with your dog's veterinarian for their recommendations regarding this dosing schedule.
