A limping dog caught on camera being dumped in a car park “is improving nicely” as three people were questioned, it emerged today.

The two men and a woman from the Preston, Lancs, area were quizzed after a man was seen abandoning the dog nearly 300 miles away in Weymouth.

He was caught on CCTV appearing to take the dog for a walk, but minutes later strode back to the car leaving the animal, which was unable to catch up due to a limp.

The man left in what appeared to be a metallic blue Mazda or Kia Rio car on September 17.

An RSPCA Spokeswomen said: “Three people from the Preston area have now been questioned in relation to the abandonment of the dog and our investigation is on-going.”

The RSPCA said it will continue to investigate before passing the case to prosecutors.

Hundreds of people have since come forward to rehome the shetland cross terrier named Ginger.

Woodlands Farm Kennels in Bridport, where Ginger is being looked after, said they have had to stop taking calls after interest from around the UK.

Owner of the kennels Mary Bull said: “We had to stop taking down details when numbers got to over 100. We have to wait now until the RSPCA say we can rehome her, as in many cases the dog will have to stay here until after any prosecution.”

She added: “Ginger is improving nicely she's been running in the fields and chasing a stick and playing tug of war.

‘“Despite what she's been through she adores having human contact and just loves people.”

‘The maximum sentence for causing a dog unnecessary suffering is six months in prison and/or a £20,000 fine.
