Twig is now 5 months old, and has list a lot of his teeth. We went through a short period of time where he seemed to settle a bit. No launching, lunging, biting and generally being a boisterous pup. He's now reverted back to being bitey and launching himself at us. He's being walked, getting rest, going out for poos & we play to stimulate his brain. Weve also noticed his coughs his boy bits popping out more often . Are we now in the adolescent stage? He seems to be pushing boundaries, could this be testosterone related? He was about to start intermediate training school but C19 has scuppered that. any help, advice, or gin would be welcome.
