I don't think there's anything that can be done here, but just in case.
Next door have three large breed, working group dogs. They are huge and beautiful. They look well cared for, are fed and not too noisy.
However the dogs are never walked. Ever. They have access to the house and a small concrete square of garden. They don't have access to the full garden as the rest is fenced off as a no dog zone.
Surely these dogs are going to have joint and muscle problems as they get older? Pent up aggression? They literally get no exercise whatsoever other than the odd scrap with each other and a pootle round the dog area, which is tiny.
Approaching it with them is a no-go. The man is extremely aggressive and volatile and I really don't want to go there.
Am I right in thinking that as long as they are fed and have shelter, there's nothing anyone can do? I feel so sorry for them. They're gorgeous dogs and as an owner of working dogs myself, I know how much exercise they should be having.
