Over the past year, there have been instances where greyhounds have been found to have high urinary arsenic levels in their systems, with the probable cause attributed to treated timber, which the greyhounds have been constantly licking or chewing.

These cases highlight the fact that kennels made of treated timber could, through greyhounds chewing or licking them, cause elevated urinary arsenic levels. Trainers are advised to be cautious about this, especially if they have greyhounds who are more prone to chewing or licking.

Trainers are also advised to be extremely cautious using vitamin supplements that contain arsenic close to racing, as these may also inadvertently lead to a rise in urinary arsenic levels.
