A Los Angeles woman made a promise when her dog fell ill and its vision started to dim - if her toy poodle lived, she would help it overcome any disabilities and give a paw up to other pooches in the process.

Silvie Bordeaux kept that vow after Muffin survived a cancer scare but lost his sight.

She created Muffin's Halo Guide for Blind Dogs, a device that encircles a dog's head and prevents blind pets from running into walls and furniture.

The halo is made of lightweight copper tubing that attaches to cloth wings and a harness fitted around the neck and chest.

Ms Bordeaux's devices range in price from about £40 to £80, and come in different designs, such as angel's wings, butterflies and sports strips.

"They can eat and sleep and play and run with it on," she said. "It's like their superpowers."
