Milton Keynes, Buckinghamshire, will host the return of the Big Doggie Do festival at Willen Lake on Saturday, 16 May and Sunday, 17 May 2026. Organised by The Parks Trust, this free community event typically attracts thousands of pet owners for two days of dog shows and activities.
Visitors can watch or take part in activities such as ‘have-a-go’ agility courses, flyball, and dock diving, where dogs jump into the water. There will also be a fun dog show with categories such as the ‘Waggiest Tail’, alongside more than 40 stalls selling pet products from local businesses.
The event takes place on the South Lake, around the events plateau near the Watersports Centre, with festivities running from 12:00 PM to 5:00 PM on Saturday and 11:00 AM to 4:00 PM on Sunday. While entry to the festival is free, standard parking charges apply at Willen Lake and can be paid for using the RingGo app or by card/cash at machines on site.
Local outlet MKFM reports the event is one of The Parks Trust’s most popular free events. Destination Milton Keynes notes the festival highlights the city’s parkland. Background research indicates the Big Doggie Do has been running for more than a decade and has grown in scale over that time.
