Thieves broke down a six foot fence to steal two sheepdogs from a property in Almondsbury.

Avon and Somerset Police are appealing for help to trace a Shetland sheepdog (Sheltie) stolen between 5pm and 6pm on Sunday, January 31.

One of the stolen dogs was found running loose near the Portway in Bristol earlier today (Tuesday) and has since been returned.

A three-year-old dog (pictured) remains missing.

If you know his current whereabouts or have any other information which could help the investigation call 101 quoting reference 5221021985.

You can contact the independent charity Crimestoppers 100 per cent anonymously on 0800 555 111 or via their Anonymous Online Form.

No personal details are taken, information cannot be traced or recorded and you will not go to court or have to speak to police when contacting Crimestoppers.

The appeal comes after Gloucestershire Police urged pet owners to be vigilant and review their security after reports of a rise in dog thefts.

The demand for dogs has soared during the pandemic due to more people working from home and having extra time on their hands.

But police say the rise in demand has led to a higher prices paid for new pets, and a significant increase in dogs being stolen.
