I used to have one of these. Very large, very fast and could run for miles. Apparently, so the breeder told me, they were first bred to hunt lions ..... they simply ran the lions into the ground. Top Tip: If ever you own one they are virtually untrainable until they are about 7 years of age. They can be taught the basics of sit, etc but if you let the buggers off the leash be prepared for at least a ten mile walk to get it back. I eventually managed to train mine to "SIT" on command but he never would come back if called. He would just sit and wait for me to catch up. After a few years of this I also got a border collie/lab first cross and she would "round him up" ... she would also round up the kids on command.

His name was "Sinbad" although his kennel name was "Prince Sinbad of........" etc. Far better pedigree than his owner.

I discovered a dog track (licenced) near where we lived that once a month ran an "Afghan" race night.
B@st@rd dogs were a law unto themselves. Unlike Greyhounds the Afghans would stop for a pee halfway through a race, if they sighted the lure on the far side of the track they were bright enough to turn and catch it when it caught up with them. I have even seen the sods mating halfway through a race but we all said the owner of the bitch should have not bought her racing when in heat as we reckoned he was hoping to get puppies for free and normal mating fees could run into £thousands!
