I have a labrador Mix. From what I have read on the internet, my dog clearly displays most of the traits, abilities, and temperament of a Labrador. However we can't quite tell what the other breed is.
One possibility is that of a pointer of some kind, because my dog will sometimes point, or stand still and stare far off into the distance while on nature walks. However, some think he also looks a bit like he might have some greyhound, or Scottish Deerhound in him. ( He has that unique large chest, skinny hip thing going on)
If my dog would prefer to find things by sight rather than smell, I think that would be important for the type of things I do with him.
What signs should I look for to know if my dog is a sighthound?

Edit 2: In my research on the net, I learned about different type of hunting dog categories, or gun dogs. Some like to retrieve, some point, others just like to go after a scent trail. Sight hounds are a bit different though and prefer to see and chase. It's easy to tell if my dog is following a scent, but I'm not sure how to tell if it is following by sight also.
