i owned a 1st cross collie greyhound that came from working farm in yorkshire the grey hound bitch was an irish bred bitch that had to be retired through a minor injury and 5 pups were born all collie coloured and all went to local lads here in north east,there was no wastage in this litter i can say with all honesty they were either 1st class rabbiting dogs or in my case fox deer dog,[pre ban] my dog glen was still doing teeth at the grand old age of 12 and would pull a fox from an earth with the same ease as any bull cross i was caught lamping one night by plod whilst dog was in full flig
