Licking
Among dogs, it is not uncommon for them to lick their lips. They do it in order to express affection. When they lick you, they are letting you know that they adore you and are proud of you. Your skin contains minerals and nutrients that they find appealing as well!
Humping
When it comes to dogs, humping is nothing out of the ordinary. The majority of the time, they do it in a lighthearted way, so it is not always sexual or a question of power for them. In any case, we will not hold it against you if you do not like it!
