The aim is for dogs to walk safely on any surface

Earlier this year, Northumbria Police announced their dogs would wear the footwear to protect their paws from broken glass during searches.

Dog Max was fitted with the Bark 'n Boots to search a factory complex in Washington last week.

As a result a 36-year-old man was found and arrested on suspicion of burglary. He later received a formal caution.

In the past, a dog would not have been deployed because of the risk of injury from broken glass which was on the floor of the factory.

Sgt David Gregory, from the force's Public Order Training Unit, said: "We bought the boots so our dogs could walk safely over any surface.

"As well as providing protection during public order situations this incident shows how useful they can be during building searches when there is often glass on the floor."
