Why Do Dogs Lick ?
When a dog licks their bowl, cleans the floor after you spill something or reaches for the counter, it’s quite obvious that he’s licking because he simply likes the taste.
Whether you realize it or not, we humans often have tiny food particles on our skin that our dogs can taste. Additionally, our skin has salt that dogs enjoy licking. Because of this, it is common for dogs to lick our faces and hands after we eat something.
So although it’s possible your dog is licking you out of affection, there’s also a great chance he’s licking because he loves the taste of your skin.
