Hi, What is the best over the counter flea prevention medicine? My dachshund, Snuggles goes outside a lot and stays indoors some but stays outside more when it is pretty outside. So he has fleas on him. Right now we are using Hartz Flea Powder but he still has lots of fleas. We weren't really wanting to use a flea collar because we scratch his neck a lot (favorite place to be scratched) and didn't want it on our hands and didn't want him laying on the furniture getting the flea medicine on the collar on the furniture. But we will try anything so all suggestions are welcome. Thanks everyone!!
