How do I get my wiener mixed with a jack Russell to stop peein in the house.

How do you do that? Well you train him/her properly so him/her doesn't do it in the house, but you have to be completely dedicated to the work to get it to happen and it isn't easy for some breeds. I for one have never had a problem house breaking a pet ever. It is sort of called tough love but the outcome is worth it.

There is an old saying 'you don't do your dog any favours by not training them'.

However, you don't say how old your pet is and that makes a difference to the answer as well.
