Get A Sloppy Smooch
One way to have your dog show that they love you is to teach them how to give a gentle kiss. Not everyone loves getting slobbered on, but most dogs kiss their owners as a sign of affection. This is one of the simplest tricks that many dogs can do even without training.
The best way to teach them is to put a treat on your cheek and give them a command to lick it off. Teaching a dog to kiss on cue can also prevent unwanted licking.
