The fastest-growing crime in the UK is theft; not of mobile phones or iPods, but of dogs. Forty thousand pooches are reported lost each year to pet insurers – and it is estimated that 50,000 dogs are stolen in the UK each year.

There have been several high profile cases recently and local papers carry reports of dog theft on a weekly basis.

So what measures can you take to keep your faithful friend safe? Take heed of these tips and it's unlikely that you'll have any problems:

• By law all dogs must wear a collar and identification tag when in a public place. Include your surname, telephone number, address and full postcode.

• Ensure that your dog is permanently identified by microchip tattoo or ideally both.

• Keep all documentation relating to your dog in a safe place. Include clear photos of front and side profiles of your dog. Make a note of unusual markings.

• Garden fencing should keep your dog in and trespassers out.

• Never tie your dog up outside a shop and never leave your dog unattended in a car.
