Hi @Bordercollierun
As @SpanielsGalore says, I'm one of the giant breed people here.
I'm sorry you're struggling with your pup.
What @SpanielsGalore and @Nella68 say here is helpful. I will just add that in my experience, having had 4 of each sex, girls take a bit longer to toilet train with wees than boys do, so don't panic about it just yet. Your girl is still very young. My current female was about 14 or 15 weeks before she was completely reliable with wees.
As far as taking her out to toilet, you need to try to avoid being tempted to bring her back in before she's done anything. If she's lying down, try to get her attention on you with a tug toy or some treats; the more she wanders about, the more likely that she will wee.
I got a female puppy when my male dog was approaching 5 years old. I used dog gates, so initially they could be in separate rooms when needed. They did integrate very quickly, but we were able to give him regular breaks from puppy duty. It might be worth you trying gates, or, as Nella suggests, a room divider.
The one thing I can't advise on is her screaming, barking, howling. I haven't had that with any of mine. It sounds as if being in the crate is making her panic, but I don't have the experience to advise on that.
I'm going to tag @abracadabra1980 and I hope she'll forgive me for doing so, but I know she has a Newf and is also experienced with dog training, so she might have some words of wisdom as to what the specific needs of Newfie pups are.
