I think that most of the time, dogs are better than people
Dogs are great companions. Do you have a favorite breed of dog? Do you currently have a dog?
Labs are my favorite!  I currently have two dogs.  What about you?
Are both dogs Labs? What color are your dogs?
No they are both pit bulls.  I had a lab that passed away a year ago.  He was the love of my life.  One is brown and one is gray
I'm so sorry for your loss of your companion. What do you enjoy the most about dogs? 
That they love unconditionally!  There is nothing better than that!
That is true. Dogs are loyal companions. Does your dog get excited when they see you?
Very excited!  They are always the first thing that greets me at the door!
Often, dogs learn the sound of you returning home before you're even in the house. Is there a routine they have when you arrive home? 
Nope just that they are either waiting at the door, or if they are outside, they know the sound of my car so they will greet me where I park it too!
