It seems that no matter how deep the fireplace hearth is, errant sparks manage to escape and leave burn marks in carpet. Help protect your floors (or cover a hole that's already there) with a hearth rug. It also provides a soft spot for your puppy to relax in front of the fire.
There are lots of pretty hearth rugs on the market, but either they're made with a top material that will char or melt (although not burn through the fire retardant backing) or they don't have a non-skid backing. A non-skid backing helps prevent you from slipping on the rug while carrying an arm load of firewood. We're also showing a black metal hearth extender here for your consideration as well.
