I love my Labrador, he's a retriever-gun dog.
OH you have a Lab?  What's his name?
Hi name's Mittens, he's one of the most popular breeds of dog in US
But that's surely not why you have him, right?
You're right, I have him as he is my favourite disability assistance breed
I have heard they make especially good guide dogs.
Correct, thats why hey are prized as sporting and hunting dogs
How long have you had your Lab, Mittens?
I've had Mittens since the sheep protection policy came in effect in Newfoundland, so about 5 years.
So he's pretty big now, right?  Like, say, waist-high to you?
