Best Answer

Scent and hearing are the main senses that dog actually have. Their eyesight isn't that good, and they have no sense of taste, smelling is how they decide if a food is good or not,because they do not possess taste buds

Answer:Smells are detected by specialized nerve endings called "olfactory receptors." On average, dogs' noses have about 40 TIMES more of these receptors than human noses.
