In my opinion there only slow to start due to owners holding them back due to the myths of them taking a while to mature if the dogs out plenty there like any other lurcher, the more stuff they see at a young age the better. I've just took on a bitch that a mate bred it's not seen much and is nearly 3 and it's not upto much at all, picking and choosing runs etc. A had the fullbrother out a different litter an he was doing it from 10 month but he was sadly pts in January he would of been 6 last month
