HE is barely bigger than a bag of sugar and twice as sweet.

At just a week old, gorgeous George is a cute ball of fluff, who will sit in the palm of your hand to be bottle-fed.

He needs a home but, if you are thinking of welcoming him into your family, be warned - when fully grown, the Rottweiler pup won't be quite so cuddly.

It is difficult to imagine now, but George will fill out into a lean, mean, muscular machine - weighing up to 110lb.

The pup has won the hearts of staff at West End's Blue Cross animal adoption centre, who have been caring for him since he was just a day old.

He was the only survivor of a litter of four puppies after his mother tragically killed the other three.

Centre manager Kellie Brooks said: "George is just adorable and already we're all very attached to him."

"He's just started opening his eyes and we are amazed at how strong he is."

George is now a week old and weighs one kilo, about the size and weight of a bag of sugar. But as he gets older, George could weigh up to 60 times as much and grow as tall as 70cm or 27 inches.

The centre is trying to find a surrogate mother but so far staff are hand-rearing him.

Also waiting for homes are two of the centre's longest inmates, former street urchins Jack the collie cross and Harvey the cat.

Jack, a former Barbados street dog, was transported to England to start a new life but was given up by his owners in Devon because of his strong chasing instinct.

Harvey the black cat has been unsuccessfully looking for a home since May, when he was brought in as a stray from Hayling Island.

Animal welfare assistant Megan Baverstock said: "He is wary of people he doesn't know. He sits quite close to the bars and when people stroke him he just doesn't interact with them - he gives the wrong impression.

"Once he knows you he is lovely and affectionate. He is a sweet cat with a lot of personality."
