Why do dogs lick people so much?
– Dogs lick as a greeting or to comfort you, showing affection and care.
– They may like the taste of sweat or the smell of food on your skin.
– Licking can also be a way for a dog to seek attention and affection.
– Excessive licking may be a sign of anxiety or obsessive-compulsive disorder in some dogs.
– It’s harmless to let your dog lick your face, but washing afterward is always an option.
– Allowing your dog to lick open wounds can protect against some bacteria but may slow healing.
– Consistent body language and positive reinforcement can help train your dog to stop licking you.
