Yorkies come in lots of different colors so you need to be a dog expert to tell if it's a Yorkie or not. But anyway, if you don't train them right, they can be a bit yappy. They are very small and cute.
Great Danes are known for how big they are. They learn fast and make "great" companions. If you like those dogs that you can hug around neck, then a Great dane is the dog for you! d
Greyhounds are known for their fast running. Their slender bodies help them manage this amazing stunt. Did you know that once there was a Greyhound that lost two of his legs on one side and could still run just fine? Cool yaw!
German sheperds are very cute as puppies. They are my personal favorite breed of dog. As adults, they pretty big. In fact, my next door neighbors have a german sheperd so big, they named him bear! Anyway, they make great companions and I love them!
