So Gus has now gone conpletly backwards in everything hes learned. Hes knocking down the kids again, biting clothes when your sitting down, jumping up on the table when we are eating dinner even though before he would lie in his bed until we are finished. Is this just him becoming a teenager? Hes 18weeks and when I tell him no he doesnt listen at all! Any help or experience with this? Thanks
He's still very young! Just keep doing what you've done to teach him how to behave in these situations keep doing it, consistency is key! But sometimes I guess we need to manage things, does he have a crate or room where he can be separate from the family at busy times? Maybe with a Kong or something?
That's because 'No' is meaningless language to him. Instead of saying 'No' ask him for an alternative/incompatible behaviour. It takes many repetitions of a behaviour in different environments before something is truly learned, so as others have said you just have to keep on training
