There's plenty of vids on YouTube of them working,,, I have put no end up over the years,,, type in podencos ,,, as we tend to call them Ibizan hounds ,, the Spanish refer them as podencos,,,
Have a look out for them hunting in Lanzerote,, running on pure rock and old larva flows,,, tuff dogs with great feet,, but there used more like our hound,,, in numbers and they open up but they do catch plenty.
