Our jack russell poos in the house every night when I leave her outside she jumps on the windows and howls I have to bring her back in because the neighbours, help what do I do?

I've seen this a lot of times with breeds that need more attention.
How often do you walk your dog? A jack russel is a very smart dog - chances are he is not getting adequate mental stimulation and this is a result of it.

Start by taking your dog out on at least one 20 minute walk a day, and see if that corrects the issue.
