Canis lupus familiaris
You're a beautiful dog with a loud bark and a feisty personality. Despite the aggressiveness, you tend to be very close to your friends and to support them as best as you can.
Life without excitement is exactly that. Boring. You enjoy being adventurous and this leads to a strong ambition that is unmatched. Unfortunately, this adventurousness can make friends hard to deal with as you often prefer doing things your way.
You're not the smartest but you are a hard worker and gets things done. You can reach most goals you set for yourself as your competitive nature forces you to triumph over the people around you.
