Well, I've trained greyhounds to run at tracks all over Scotland, and still have my license for Shawfield Stadium...Scotlands only NGRC reg track and home to the Scottish greyhound Derby.
Greyhounds are born to run, there is no finer sight that a fast dog at full stride. Despite all the bad publicity, the dogs love to chase the lure, I used to travel over 100 miles both ways to race my dogs, sometimes three nights a week and the dogs knew when we were getting near the track....they got really excited, desperate to race.
Why don't you buy a sapling and run it at a flapping track? If it turns out to be fast you can transfer to a NGRC track.....you might even end up with a Derby winner! Owning and racing greyhound is one of lifes great experiences!
If you want an old dog, you won't get a better house dog...as John says, they love to lie on the sofa with their big long legs in the air, you rarely come across a visious or bad tempered greyhound.
As far as training is concerned, forget it! Greyhounds dont do tricks, but are affectionate and clean preferring to go out somewhere private to do their business. They are rather aloof dogs, never making an exhibition of themselves by licking or slavering over their owners......in fact in a very short time the hound owns the man. Get one and see what I mean, one thing is certain, once you are adopted by a greyhound, you will never want any other species of owner......enjoy.....Ake.
