Average stray/feral dog home range?

[989]

I am working on a paper about stray and feral dogs, and I am struggling to find information about the size of territories and home range (the area they frequent throughout the day in search of food and such). I am aware of the beck study, but that's only one study in a limited area, and I have been looking for more sources that can confirm Beck. It doesn't seem like a subject with much written on it, though... but if you know any, please link me any (preferably free) studies on the subject that you know of!
