WELCOME!!!! Please post pictures soon
I fence Mocha in during the night. her dinner is around 6PM, then she will poop immediately after, or 3/4hours later. Another pee session before bed, and she will sleep through the night. She is wee wee pad trained though, so if I wake up later, I do not have to worry of her having accidents in her "room". Below there's a picture of her room.
Well Mocha has had accidents on my bed.. Which is why I don't sleep with her until I'm really convinced she won't do it again. Lately though, I can tell when she's on my bed and needs to pee... She will move more sharply than usual, but it is the kind of things that differ from dog to dog. We haven't had an accident on my bed in months, so soon I will get a lower bed and sleep together
I wouldn't recommend putting him on your bed until he's at least 6 months, but there are many opinions on this
Just remember that if he pees on your bed you might have to get it professionally cleaned. I don't know if there's any product that will prove to be more convenient.
When I was considering crate training, I read this:
How To Housebreak A Puppy
It might or might not help you, but it might give you some a place to start
Congrats again! Jaxx is such a cool name.
