Dear Stacy {{{Hugs}}} across the miles - my heart goes out to you - it all sounds so terrible.
At least getting Kambles anti-bark collar back on has solved one problem - don't barking dogs wear your nerves to a frazzle?
Maybe you just have to be bloody minded with your Mum and just tell her to take her poopy dogs home with her - their not your responsibility.
Good luck - hope things improve - vastly.
