The owner of Tyko, an overweight Corgi cross, was told she was "killing it with kindness" before the animal was taken by the Scottish SPCA and put on a strict diet.

Vets said the pooch was so fat he resembled a seal.

The animal managed to lose six stone during the weight-loss regime.

Tyko used to be so fat he could only take a few steps before becoming breathless and slumping to the ground.

Now he is a healthy weight after the successful diet and exercise programme.

He has gone from 49kg (8st) to 12kg (2st), so has lost his healthy bodyweight three times over.

His weight had ballooned due to over-feeding and a lack of exercise.

The animal charity is now trying to find him a new home.
