The seven-foot pooch, named Balthazar, has to sleep in specially made beds .
He chomps his way through £108-worth of dog food every month and rules the roost in his owners’ house.
The five-year-old pet measures 3ft 3in from his paw to his shoulder and is 7ft from his nose to his tail.
He lives with owners Vinnie, 46, and Dixie Monte-Irvine, 39, and their three children in Gedling, Nottingham.
While not Britain’s tallest dog – that crown goes to an 8ft Great Dane in Swansea – experts believe he is the country’s heaviest.
Vinnie was shocked when he took Balthazar to the vets last week and the scales clocked a whopping 15st 6lb.
He said: “He is a big dog but isn’t a fat dog though as you can still see his ribs.
“We were told from when he was a lot smaller that he was always quite heavy for his age.
“We took him to the vets as he has a poorly leg and he needed to be weighed to see how much medication he can take.
