Hi KeiGirl! I don't personally have any experience using Comfortis, but the flea medication itself does not have anti-itch properties. If your pup has already been bitten by fleas, that is probably the cause of the scratching. It is also possible she is having an allergic reaction to any bites. Inspect the area and make sure everything looks ok. Constant scratching, biting, licking is definitely not good for them. You may want to give her a bath with something that will soothe her skin. Something with oatmeal is usually good. |
