9. Sagittarius (Nov. 22 – Dec. 21)
A Sagittarius craves adventure and excitement and welcomes change with open arms. They love to explore new terrain and will go as far as the road will take them. A Sagittarius needs a dog that will share a love of adventure and freedom. Greyhounds are generally calm and enjoy structure, but what they really love is to run freely without anything to hold them back. Greyhounds make excellent jogging companions and adventurous sidekicks. They are highly adaptable and will adjust to new surrounds with minimal effort — perfect for an adventurous Sagittarius. If you prefer a lap dog, consider a Yorkshire terrier.
