Rescue dog Kahlua makes claim for being the world's most-travelled pooch (4)

The travellers have already climbed to the summit of Colorado's Raspberry Mountain (pictured) and been to several states

'But at least when I look back on my life I will know I made the most out of it while I could. I can't imagine living a life full of regrets and "what ifs".'

He is capturing every moment of their trip and sharing the stunning photographs on his Instagram account and personal website.

Along with his life savings, DeHaas is putting any money raised from his photography towards funding his journey with Kahlua.

The optimistic traveller thinks the fact that they have shared so many adventures has made their bond even more unbreakable.

He said: 'It's been one heck of an adventure. Kahlua's done more traveling that most humans I know and we've only just started to scratch the surface.

'I may be biased but I think she is the perfect adventure dog. She's always down to join me and every new escapade brings us closer together.

'She inspires me to live life to the fullest. It became a goal of mine to try and give her the most exciting life possible.

'I had never been someone to hike a mountain but Kahlua's love to be outside rubbed off on me and now I can't imagine not being outdoors.'
