Dogs were the first animal to be domesticated by humans over 20 000 years ago and they have been our furry companions since then! They are playful, friendly, and loyal; and this makes them great companions. However, dogs can also be fierce and tough, making them great protectors and helpers. They are smart enough to be taught commands and tricks, and they can be trained to assist people by working as guide dogs and emotional support animals. Thanks to their sharp senses, dogs can also perform search and rescue tasks! Dogs come in all shapes, sizes and personalities — from the affectionate Cavalier King Charles Spaniel, the protective German Shepard, there's a dog breed for everyone!
