sorry to hear about your bad luck mate. i had a kerry blue greyhound a few years back totally stock broke then when he was about 4 years old was walking by some sheep one of them was stuck in the fence by her head and started going crazy, next thing i knew the dog was on the sheep.i got a hold of him and gave him a doing never looked at a sheep again and i had him till he was 15, ithink he just got a fright or something and his instinct set him off.i gave him a second chance but i dont live next to any so any time i would have been with him.
sorry again jo
