You could try replacing the big doghouses with smaller ones. I found this 3 New Pet houses for cats or dogs large and small versions.

Or put out a couple of those weird fish bags for cats, or a couple of cat condos, I have those outside for the cat and the cat sleeps in those all the time. The big doghouse is probably attracting the dogs.

Ashara is going to come up with a really nasty surprise for Neloth. Maybe a micro nuke that affects only one person
