Winstin was around five months when we had him done. However, he has lifted his leg since he was just under two months old. We never had trouble with him marking inside. I was worried about that. He has recently started running around outside peeing three times before coming in. He likes our fence and also likes the tallest blade of grass. It's funny. We really laugh when he goes to lift a leg and about falls so he lifts the other one. He was 13 months yesterday.
