Presley is a pure bred lab.. She is reg through the CKC (Canadian Kennel Club). You are more then welcome to take a look at her pictures.
There is basically 2 types of labs, But i will post a link to a site that they basically say there is 3 types. One is the *English* type. They are more bulky,boxy head,shorter to the ground, and distinct otter tail. They say they are more stronger willed.
The North American is taller, leaner,longer face, And they say they are is not too active and not as strong-willed.
And this is what they say the thrid is... The field trial type. I believe Presley falls in this line!! She is bred for this. A dog that was trained for his working ability. That can be either type (English or American). THe feild trial active, strong-willed dog and it needs to do its field trial work. Presley was bred for hunting, Also her mother has some feild/hunt titles under her so this will be what we will be trying with Presley.

Anyways here is a site you can read about lab types.
