Taina , sorry for my little english, because I speak frensh ! boomslang say, all rr look thin like Pharaoh Hound , so I have posted some pic about big rr ! In my opinion a rr can be strong, large and muscular with only 35 kg ! yes, a good dog for the show must weight 45 or 50 kg, very big dogs are better in the show, those dogs can be good for the hunt , but less than the rr more thin ! but a thin and muscular rr about 35 kg is better for the hunt ! however, I want to buy a rr from south africa and I think that dogs from Glenaholm look thin and strong ! ps : I'm not an hunter ! I'm just looking for a dog who can run with me when I do my joggin or when I'm on my bike ! I want a dog with wind !
