Puppies become Juveniles or Adolescents from 10 weeks to 9 months. This is the time when they also discover sex. (No photos in case I get accused of propagating pornography!)
Well Jamie started bonking Jemma from day one. I believe that ignoring this behaviour is the rule of thumb which I do find difficult as Jemma has now taken to bonking my leg.
Now is the time when you start thinking about neutering and spaying. Females usually come into heat anytime from 6 to 8 months which is why it is recommended that you spay at 6 months.
However I am not panicking yet as Jamie practises safe sex. He bonks Jemma's head.
There are times when I fear for the safety of his private parts as Jemma is not unknown to give them a painful nip. He may well lose his manhood well before he is due for the snip!
Jamie cocked his leg for the first time at about four months - a rite of passage I sentimentally thought quite sweet. But other owners bemoan the start of territorial marking when males pee on everything in sight. Jamie has already embarrassed me by peeing on some body's T-shirt which was lying on the ground in the park. I had to grovel and offer to dry clean it. Once again I am paying for my dog's adolescent behaviour!
