I did this a few years ago and the pup i rared broke its neck chasing a fox.
It tripped and rolled over.
Greyhounds are just too fast for their own good.
Only one i seen that was any good, took a lot of rabbits on the lamp and had a very good turn of speed, but was fecked after 10 rabbits and would sometimes collapse!
Grand dogs to cross with a collie mind and if the right one is used, a better dog is produced for the rough irish country.
My father races greyhounds, that's how i got to have a pup for hunting, she was too small to race.
