A dog diagnosed with an extremely rare brain disease has to spin around in circles before moving. 

Penny, a seven-year-old pug from Ipswich, was diagnosed with lissencephaly five years ago. 

The disease is a brain condition that affects coordination and movement. 

Penny's owner, Clare Yelland, said the condition means the pooch has to spin in a circle before walking and veers off to one side.

"Penny can't go straight and before she moves she'll spin in a circle," said Mrs Yelland. 

"She carries on as normal but we do have to scatter her food on the floor as she struggles to get her head into a bowl."

Mrs Yelland and her husband Leon bought Penny when she was a puppy as a Christmas presents for their children, Nia and Stanley. 

Penny always spun in circles but when she was three years old, she had a seizure and was diagnosed with lissencephaly after an MRI scan at a specialist vet in Newmarket.

Despite the condition, Penny is not on medication and continues to live a normal life alongside the newest addition to the family - a 15-week-old pug called Priscilla. 

"We thought it might give Penny a burst of energy as an older dog," said Mrs Yelland. 

"Penny spins in a circle away from her and won't even make eye contact half the time."
