While Yada Ornsomjit was sleeping, his French bulldogs in Lamphun raided an open cupboard that contained, amongst other items, a bag of green food coloring.
In amusing footage of their escapade, the dogs leap around their kitchen in Lamphun, northern Thailand while covered in the green powder.
Owner Yada Ornsomjit found the brightly coloured dogs named Dam-nam and Sai-Au on Saturday, July 13 after leaving her door open.
Their unfortunate makeover had left them looking like the famous Marvel Comics character The Incredible Hulk.
Ms Ornsomjit said: ‘I forgot to shut the kitchen door the night before. But I couldn’t believe they went inside and made everything green.’
The colouring had spread across the kitchen floor, and been traipsed around the house by the cheeky dogs.
Ms Ornsomjit said: ‘My husband and I spent half a day washing them about three times but some parts of their bodies were still green. We were really tired but they seemed not to know what they had done wrong.’
