We have a lab/pointer cross (perhaps a few other things mixed in too...)
Personality wise can get a bit aggressive but unsure if that is due to breed, or having a bad upbringing (adopted).
Health wise he has had no major problems. Had a grass allergy when he was young and would get boils in between his toes, but again, I doubt it is a common trait among his breed.
He is nine years old now, and going just as strong as when he was younger.
Healthy dog, really fast, needs a lot of walks.
