Why does my puppys breath smell like blood?
Although your puppy's breath might never smell like flowers, during the teething stage, the sweet and sour smell emerging from his mouth is especially potent.
This is because your puppy's bleeding gums and the warm, moist environment of his mouth form the ideal place for bacteria to thrive.
Dogs also lick because they like the taste of an owner's salty skin and out of habit.
Mostly, with domestic Dogs, it's a sign of affection.
Licking releases pleasurable endorphins which gives Dogs a feeling of comfort and pleasure — like the feeling people get when they are biting their nails — it relieves stress.
