It doesn't happen often
but I am fully in agreement with Toddy!!
Those dogs do not need a dog village in the forest. The forest sure as heck doesn't need several hundred feral dogs hunting through it. I cannot think of a single situation anywhere in the world where a large number of previously domestic type animals going feral and running loose over the landscape has been a good thing.
Trying to move a significant number from the town to the forest seems like it has low odds of long term "success", like trying to brush water uphill! I write "success" because if you succeed in making your dog village sufficiently comfortable with enough food around to hold the dogs in the area, chances are they will make puppies and increase the feral population, which doesn't seem like it should be the aim.
If you wanted to change the lives of a few dogs (starting small and seeing where it goes) I think you would be far better off trying to create a stray dog training and rehabilitation centre in town. Take in strays, feed, medicate, neuter, train and attempt to re-home. Doesn't sound as exciting as building dens in the woods, trapping food and living with a dog pack, but more likely to be of benefit to your town and the dogs.
