Hi guys, so my chihuahua, Brows, is 6 months old this Sat and he has been cocking his leg to pee without wobbling or falling for around 2-3 weeks now. I have noticed for around a week or so he has began scent marking outside like crazy! To the point where he will pull frantically on his leash to get to the next post or bush. This is all well and good until yesterday when he cocked up my lamp and my sofa cushion and then in my cats tray....then again lots at my sisters house. Aswell as this unwanted behavior he has picked up a couple of others in the last couple weeks to go with the scent marking. He is less interested in me, he barks much more, he has began growling when he is tired or when playing with a toy with me and I attempt to touch him. I have bought a clicker and have done bags of research on positive training techniques and these are all under way I just wanted to know if this is normal adolescent behaviour or something that will be helped by castration?
