I have a dog named Spike. He is fun to play with with.
It would interest you to know that the dog is the  most widely abundant terrestrial carnivor
Yeah that is interesting to know. Dogs have been living with humans a very long time.
I totally agree with you, he dog and the extant gray wolf are sister taxa
Do you have a dog? I have one. He is 9 years old.
I don't, it's interesting to know that modern wolves are not closely related to the wolves that were first domesticated
Huh, that is very interesting. I wonder who the ancestor of the dog is.
I m not sure but let me tell you this for sure that their long association with humans has led dogs to be uniquely attuned to human behavior
