Comfortis Chewable Flea Tablets for Dogs

Comfortis is first of its kind flea treatment in chew form. It treats fleas and flea infestation in dogs and puppies. The beef-flavour makes it easy to administer in dogs. Comfortis is 98% effective in treating fleas within 4 hours of administration. Within 30 minutes, its fast acting formula starts attacking fleas and controls further flea infestation. This oral treatment prevents flea-infested diseases such as Flea Allergy Dermatitis.

Please Note - This product is recommended for both dogs and cats. For the specifics, please refer to the product box.

How does it Work?

Comfortis contains special insecticide Spinosad. This ingredient belongs to spinosyns class of insecticides that are non-antibacterial tetracyclic macrolides. Spinosad directly affects neurons and results into involuntary muscle contractions. This leads to paralysis and ultimately fleas are destroyed. It protects dogs and puppies from flea re-infestation.

Comfortis Plus for Dogs

Comfortis Plus is an advanced version of Comfortis with the additional efficacy to protect against heartworms and intestinal parasites as well, besides killing fleas. It starts working within half an hour and eliminates the infestation within a day. The product also treats Flea Allergy Dermatitis as well. Learn More

Thanks for this product

My doggy gets bad reaction to flea bites, so this fact acting product is great for him. I hide this chewable in the food and give him and there are no side effects after taking it. I am satisfied with this product as my pooch is free from my fleas.



A quick remedy to control fleas and no worries of dorgie going in water. Love it as no mess of topical treatment.


Works Great!

I'm pretty happy with the way this product has turned out for our animal.


Will buy soon

I have no complaints with this brand, in fact I'll be ordering more of it within a week.


Glad after using this!!

I m lucky to have it ,it works too fast without any adverse reaction.

Have A Question?
Q: You state Comfortis can be used for cats as well, does this apply to Comfortis Plus as well? I am having a hell of a time with ear mites in cats even though they get treated with Revolution Plus. I think most of the product gets licked or scratched off to be honest. I would much prefer a product in tablet form.

A: Comfortis Plus only comes for Dogs.
