Hiya Hugo is 18 weeks now and I would say pretty much house trained ... However he still sees no problem in using his crate as a toilet -how can I sort this or will it come in time - during the night he will often use the newspaper corner and occasionally if he is crated during the day (even for short period). He wouldn't think about going on the floor in the house will always go to the door.
I would take out the newspaper, give the crate a really good clean with Simple Solution, then put new vet bed in there with a blanket making sure it fills the whole crate. ...
