Dog trekked 10 miles and survived being hit by car on a motorway to get home after he escaped from dogsitter Collie cross Breeze has an irrational fear of humans The 10-month-old fled into unfamiliar countryside after escaping from minder He incredibly turned up 18-hours later at his owner's PARENTS' house An intrepid pup trekked 10 miles over 18 hours, surviving a collision with a car at 70mph. as he made his was home after running away from a dogsitter. Eight-month-old collie cross Brieze had fled after his owner, Sarah Walter, left him with a temporary carer while she took her other dog to a chiropractor. Already a highly strung animal, with an extreme fear of humans, he panicked and disappeared into a huge field in the middle of the unfamiliar Gloucestershire countryside near Staverton. Adventure: Sarah Walter with her dog Brieze, who ran away from a minder but found his way home in an epic 18-hour, 10-mile trek which included crossing the busy M5 Ms Walter owner feared the worst when police called to say Brieze had been hit by a car on the M5 and limped away. She spent four hours searching for dog on foot and by car, but in vain. It was only after she had given him up for dead when her parents called to say Brieze was outside their house. He had somehow made his way to their home in Leckhampton - a location he'd ever only visited by car - and was barking outside their window. Overjoyed Ms Walter, 49, of Up Hatherley, Gloucestershire said: 'How he got to my parents' house, I don't know. 'He wouldn't have had a clue how to get there and every time I've gone there with him, I've done the journey in a car. He must have an in-built navigation system. My mum just stood back from the door and he ran in. He will have been running for 18 hours. He's still shattered now. He's come through his journey quite well.' She added: 'He has an extreme terror of all humans. He's only just been starting to accept my parents.' Busy: Ms Walter owner feared the worst when police called to say Brieze had been hit by a car on the M5 (pictured) and limped away. She spent four hours searching for her dog on foot and by car, but in vain Incredible journey: Brieze made his way 10 miles across Gloucestershire from Staverton to Leckhampton Brieze went on the run last Thursday morning and turned up 18 hours later at 4.50am the following morning. Ms Walter, who supports children with special needs, said: 'He was with a carer for the day because I had to take my other dog for some chiropractor treatment. 'He'd been there before and he knows her. But I had a phone call to say he had escaped. He's a bit like an eel and gets past you if he wants to. He had managed to squeeze through the secure paddock and into an exterior area. Then the police called to say he had been sighted on the M5 and had been hit by a car as he crossed the motorway. They added that he had run off, but I believed that being hit at 70 mph would not be survivable. I was inconsolable. I didn't know what to do. I didn't think he would have run. I thought he would have stayed in the field. I spent the next four hours searching on foot and in my car, up and down the motorway and across the surrounding farmland without success. Eighteen hours later I got a call at 4.50am from my mum saying Brieze was barking outside their window. 'He must have an in-built navigation system': The most remarkable aspect of Brieze's saga is that he finally turned up at the home of his owner's PARENTS, a location he'd previously only visited by car Brieze has an extreme fear of humans which manifests itself in him charging and barking at people and circling them. He has been referred for psychological help to a behaviourist. He is still recovering from the physical exertions of his journey and is expected to fully recover from his experience after a little more sleep.
