DOG owners have legal responsibilities under the Animal Welfare Act to ensure that their dogs are the correct weight. So I trust that either the Retired Greyhound Trust or the 'concerned member of the public' referred to in the article (Dog saved from brink of death, December 17) is trying to bring a prosecution for what would appear to have been an offence committed against Danny 'Twiglet'.

The 'bad home' or, rather, bad owner, if not banned by a court from keeping dogs, could acquire another greyhound or other breed of dog and impose misery and starvation upon that animal, too.

The greyhound racing industry has had 80 long years in which to take responsibility and make proper provision for the welfare of greyhounds, but it fails to ensure the wellbeing, from cradle to grave, of many dogs associated with the sport.

On its website, the League Against Cruel Sports asks: "What is wrong with greyhound racing?" It might be easier to answer that question by stating what is right with it – nothing!

That charity is not alone in its concern that the welfare of racing greyhounds is being ignored. It states that just 3p in every £100 gambled on greyhounds is spent on retirement provision for the dogs.

Welfare groups are not simply concerned about the injuries which racing can inflict upon the dogs but also about the fact that too many dogs are bred (could Danny have been one of those?) and that thousands of greyhounds go 'missing' each year including young dogs which fail to make the grade and the track.
