***Phew!***
in my house lives, ONLY one dog, One Down, who doesn't usually fight with other dogs as he hasn't spent much time with other dogs.
In my other home..my German Shepherd lives alone and cannot fight with another dog, but, don't worry, she has lots to explore in that home She isn't alone or doesn't get bored or anything, she guards our home and with that, she enjoys running around the home, so my pets are away from fighting with each other or the street dogs

Sorry to hear about the other PT dogs and their deaths and fight... Prayers for their owners and hopefully everything will be settled soon, extremely soon.
