Often it is the owners who are a big problem - we had a hideous, noisy and dangerous dog next to us - with an owner to match! But when another neighbour minded the dog for 2 weeks it turned into a happy friendly dog. Then the owner came back and the dog quickly reverted to type. Eventually the dog was put down after a particularly vicious attack. Unfortunately this option wasn't available for the owner
- but he moved out after his wife left for greener pastures. Good result all round and our new neighbours are a vast improvement, as is their dog.
