　　Dogs are able to help all sorts of people with disabilities live their lives.Now a man from the United Kingdom has made a dog­controlled washing machine so that dogs can help these people with their laundry too!

　　John Middleton of laundry company JTM invented the “Woof to Wash” washing machine that makes it easier for people with disabilities to get their clothes clean.

　　Loading，starting，and emptying regular washing machines involves movements that most of us don’t think twice about and take for granted.But doing laundry can be difficult for people who have autism(孤独症)，are blind，have learning disabilities，or have limited movement in their hands.

　　“We developed this machine because mainstream products with complex digital controls seldom meet the needs of the disabled users，”explained Middleton.

　　“But then I saw a video from the charity Support Dogs，where a dog strips a bed and loads the washing machine.I was completely blown away and instantly thought I could invent a machine where the dog does everything.So I got in touch with Support Dogs and they loved the idea.They said it would be a huge help to their severely disabled users.”
