Dog lugs every now and then lugged two 51 kg pigs one after the other , one boar one sow one day but went to grab the boar and he let go so had to put quad runner on top and use a claw hammer as i had forgotten my gun , then we hit up a sow 51 kgs as well and he never looked like letting go so i thought to my self he'd finally turned the corner and was going to lug up , but the following week just bailed and never looked like going in which suits me as im to slow get to the dogs nowdays so i carry a tracker and a gun and havent missed get pigs with him every time ive been out for last eight months and i go at least once a week quite often twice , Rick L
