Dogs are man's and woman's best friend.  I have two and love them dearly!
Agreed the domestic dog is the most wonderful thing on earth. What type do you have?
I have a huskador and an Australian Shepard/Husky.  Do you have dogs?
 I have a pit bull. I'm glad dogs were the first species to be domesticated 
Awe!  My parents had the sweetest pit bull mix and my cousin had an awesome full-blooded pit named Butch.  I am glad dogs were the first domesticated animal!
I want a second dog but something different. Dogs vary widely in size. I think we want something bigger.
Big dogs are great!  I prefer my dogs to be at least 35-40 pounds.  What are you thinking about getting?
I'm not sure. I'll rescue a giant dog. I used to have a dingo hybrid. Half dingo and half domestic dog, maybe i'll get another.
That sounds like an interesting breed.  I want a German Shepard because I always had one growing up, but their reputation with children is not very good.
It could be because New research seems to show that dogs have mutations to equivalent genetic regions in humans.
That is so true.  Pit bulls take the worst rap, but can be the sweetest dogs.
