This week at Guide Dogs we wanted to let you know about our Facebook Advent Calendar.

The campaign starts on the 1st December and will finish on the 25th December. Each day in December a door will unlock, and behind it will be either a puppy photo, what our SAP puppies are doing for Christmas, festive videos, competitions, Facebook cover photos and Desktop wallpaper downloads.

On the 10/12/2014 we are running a competition entitled 'Email your festive photo.' We are asking our Facebook followers to send us in a picture of their puppy in the Christmas spirit. The chosen winner will be the SAP Facebook profile picture until Christmas eve. All entries to be submitted by the 15th December and announcement of winner on the 16th.

On the 14th December we are asking our Facebook followers to share our 'Barking Dogs - Jingle Bells' video' with the hashtag #SAPadventcalendar. At random one of those who shared it will win a trip to the Guide Dogs Training School. Announcement of the winner will be on the 20th December.

Why we need your help

- Every hour, another person in the UK goes blind.

- 180,000 blind and partially sighted people rarely leave home alone. Guide Dogs is committed to changing this.

- A visually impaired person could be partnered with as many as eight dogs in their lifetime, and each partnership costs £35,500.

Please donate now and help us train more guide dogs. The more guide dogs we train, the more lives we can change.
