While some flea collars are generally safe to combine with topical flea medication, I do not recommend using either of those products on Khloe. Both are poor quality products that do not work well at all, and Hartz is especially poor. Many animals have had bad reactions to Hartz products, as well as still having problems with fleas. I can give you the flea treatment program I always recommend, which works very well and is safe for Khloe. First, I would give her Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash her bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. I hope this helps!

    You can use these products together, however there are safer and more effective products you can use to control fleas. Some of the products I recommend are Comfortis, Bravecto, and Nexgard. These are all very safe, work very well, and are oral tablets so you don't have to worry about applying anything to the skin.
