Rhodesian Ridgebacks are beautiful dogs and great guard dogs. I have had Bull Mastiffs and Boer Bull's which tend to last up till around 8 years of age. In breeding is a problem and our current Boer Bull looks like he is a proper pedigree. He is big in a good way and is solid muscle. We have tried to keep him on a diet so his legs last longer yet he is still around 75kg's. Nadi will not have hip problems and she does look really good for her age.
