used to have ex track greyhound, was told i can never let him off the lead cos he will run off and kill small dogs and anything he can catch, 10 days later out in the forest off lead, another 10 days walking around ponys and cows off lead. even had him chilled out at my mates house with a cat in the room. it can be done. ps,, got my jackrussel at 7 weeks three years ago and still cant trust him with anything. lurchers are alot easier. thay usaly want to catch, trick is showing them what. as with recall should improve when you bond
