It turns out that they are North American Cheesehounds. Their noses can hone in on all types of cheese from great distances. They can hear the crinkle sound of a package containing cheese from at least 2 rooms away. Their long low bodies are perfect for getting to any cheesy morsel that may have gotten out of the range of any larger breed. They also come equipped standard with extremely cute faces that renders their owner defenseless so they will relinquish the cheese without a struggle. It is unwise to look at the photo too long, you may find yourself running to the kitchen to find some cheddar to give to the nearest lowrider dog.
