A nine-year-old girl has been left heartbroken after her dog could no longer walk after developing a mystery condition overnight.
Young owner Ava Davies, from Walsall, West Midlands, was diagnosed with DiGeorge syndrome, a condition present from birth that causes a range of lifelong problems, including heart defects.
Brave Ava underwent open-heart surgery at just three-days-old at Birmingham Children’s Hospital before being diagnosed with the rare condition which impacts just 1 in 4,000 births.
