It will work in the same way again - this week's theme will be 'Dogs and Balls' to celebrate the start of Wimbledon & the continuing World Cup.
To enter, simply tweet a picture of your dog(s) which you think fits the theme to @BlackDog_Bakery before 7pm UK time on Tuesday 24th June and include the hashtag #TreatTuesday. Entries are welcome from both human & dog-based Twitter accounts!
Shortly after 7pm, we will 'retweet' all of the entries, and the one with the most 'favourites' on our retweet at 9pm, will win a £5 voucher to spend at our online shop!
