Dogs are such great animals! I have one, a golden retriever named Blue who is 4 years old.
Wow, I want a golden retriever too because they are so easy to train.
Yes they are good dogs. They would not make good guard dogs because if an intruder breaks in, they would want to play with them!
I agree, they're so cute. They also make good hunting buddies because they can retrieve shot game undamaged.
Yup, that is due to their soft mouth. They can also hold an egg in their mouths without breaking it!
That's awesome! I love their long beautiful coats. It helps them repel water. 
So do I, one side effect though is that they shed loads of fur that gets on everything.
I can only imagine, but their influence on mankind has earned them the reputation of "man's best friend".
Yep, we have had relationship with them for thousands of years, so their behavior is ingrained in them through evolution over the years.
Dogs perform so many roles for us like providing therapy and companionship. We really don't deserve them.
