I had my male (Jack) neutered @ 14 months when the female (Josie) went in heat. I had both of them neutered and spayed at the same time. Jack was too big to father Josie's babies so I decided to fix her too. Jack was back to his normal self in 48 hours. He is still spunkie and sweet. He quit marking his spot quit a bit but I have found wherer he marks here and there not sure why he just started doing it again. I have seen him also squat to pee-pee too. Oh and the "lipstick"
how gross! I could not stand anymore to see that thing hang out. First time I seen it I thought something was wrong with him. LOL
