My Dog Smells Like Toast. One of my rottweilers smells like brown sugar on his cheeks. Why does my dogs urine smell like burnt rubber?
This is the gas responsible for the rotten egg fart smell. Sufferers report smelling hydrogen sulfide (rotten eggs), bad perfume, garbage, a gas leak, wet dog, pungent body odor or spoiled fish or feces. I think my nose is malfunctioning.
