I don't fully understand the docking thing, why are the tails docked for working animals......does it improve their quality of life at work? Is it a bit of a fashion thing....."Tail tidy"...?


at "tail tidy"!
Working dogs is a broad definition, covering just about anything not solely a pet. They could be gundogs to guide dogs, sled dogs to sheep dogs - the actual uses are immensely varied.
When spaniels are used as working dogs, that usually means field dogs or gun dogs, running through crops, brush, trees etc. They are exuberant in their approach to work, and their tails can, and do, get severely damaged in a way that doesn't often happen to either spaniels which are pets or used for search, rescue or other forms of detection work.
When an adult dog's tail is damaged it can be a serious issue for the dog. Anaesthesia is not as routine for mutts as it is for humans, for instance, and you can't prescribe bed rest to a spaniel. Docking a pup is really straight forward and the chances of a problem are slight.
So yes, in brief, it does improve the quality of life of a working dog but for pets, etc, it is mostly about the vanity. And the decision has to be made in the first three days.
That said, our Lab damaged his tail wagging it against a door frame when I came home from work. Just one of the ways that damage can occur in a house. When in woodlands, there are a million more ways an enthusiastic spaniel can beat itself up.
