As he gently nuzzles the nose of an RSPCA inspector, it's hard to believe anyone could abandon little Bob - the black and white puppy is one of the tiniest ever rescued by the charity.
But when he was just eight weeks old, and weighed less than a kilo, was found dumped in the car park of a veterinary practice.
Huddled by a cardboard box, he was shivering from extreme cold and in agony suffering from a ruptured eyeball.
Medics at the surgery in St Albans, Hertfordshire, claim it is a miracle Bob, who also suffered painful skin blistering and canine scabies, survived the night.
Unfortunately, his condition was so bad there was nothing they could do to save the sight in one eye.
'He is a fighter and is pulling through and I just hope we can find the person responsible for dumping him.'
Bob was handed into the RSPCA by veterinary staff, who found him abandoned in their car park on April 27.
It is believed the unwanted pup had been dumped by its owner the previous day and left to fend for itself overnight.
He had been left in a cardboard box, but had managed to get out, and was wandering around aimlessly in the car park.
Bob is expected to be cared for by RSPCA officers until he had built up his strength and he will then be rehomed.
