That kind of mistreatment is sickening, although far, far too common in this country. Can you get a friend of yours, someone who doesn't live in the estate, to complain on your behalf if they don't mind their name being used? The dogs unfortunately can't speak for themselves - it looks like its up to you to risk falling out with your neighbours if you want to save the dogs.

I have heard of so many neighbours and colleagues having their pedigree animals stolen for use in puppy farms - these poor dogs literally get bred to death - if only people would neuter their dogs, they have no value to the thieves then.
