housebreaking pointers please

[smorgan]

hello!

I was wondering if anyone could could give me a few pointers on housebreaking?

My puppy is border collie,sheltie and a little bit of shepard mixed.

As well, I do have a cage for him, which he goes to sleep quite well in the evening but when he wakes up in the middle of night he of course goes outside to pee and then when he comes in he howls when I put him back in, to the point where I have to take him to bed with me.

Help!

Thanking you in advance,

Nathalie and rex
