They were very good and protective dogs, and would definitely give their life to save yours. For their mid-size, they were powerhouses and all muscle.
I was looking for some info where it says that they are a very rare type of breed because they are one of the very few that are sight/smell/hearing type of dog. Most dogs only have 1 of those traits (if I remember right). I found part of this info at Wiki: Sighthound and Scenthound (didn't mention hearing).
I found a couple of nice pics, and screencapped a brief description to go with them:
This dog was so intelligent that once he was introduced to guests by the owner, we could come and go at will,
but if a stranger came on the property he would challenge them.
The owner said that he was pretty fierce with locals that he didn’t know.
I think this dog must have been on large for a Rhodesian, he was awesome.
