 Terrier work has come under criticism from animal welfare groups in the UK, particularly in connection with fox hunting, where terriers may be used to flush out a fox who has gone underground.This has led to the terriers attacking the foxes rather than flushing them out, causing a very distressing and prolonged death of the fox, serious damage to the terrier or even death of the terrier on occasions.The Countryside Alliance have been challenged on their statements of claiming that no distressing and prolonged deaths occur during digging out or flushing out of foxes.
