Fluffy could be Britain’s biggest rescue puppy and is likely to grow to the size of a small tiger.
The Caucasian Shepherd Dog is only ten months old but already tips the scales at 44kg.
She is 5ft 6in tall on her back legs and when fully grown, she will stand at around 2ft on all fours.
Fluffy is likely to reach between 60kg and 80kg as an adult.

The puppy is currently being cared for at the Dogs Trust in Ilfracombe, Devon, after she was picked up as a stray.
The Shepherd, also known as a Caucasian Ovcharka and Russian Bear Dog, is among the largest and most powerful dogs.
Regarded as ‘brave and strong-willed’, they are extremely strong and originate from the Caucasus Mountains where they were used to protect livestock from wolves and bears.
On her back legs she is as tall as the average Dogs Trust employee and will need to live in an adult-only home with owners who are experienced with giant breeds.

Elise Watson, rehoming centre manager at Dogs Trust Ilfracombe, said: ‘When Fluffy first arrived, we couldn’t believe how big she was for her age.
‘As a ten-month-old pup she is going to continue growing, so we would love to hear from potential owners who have a lot of space in their heart and home for this loveable larger lady.
‘Fluffy loves to play but sometimes forgets how big she is which is why we would recommend an adult only home with owners who can provide her with all of the training and socialisation she needs to grow into a confident loving adult.
‘Owners should also be aware that Fluffy is a large, strong dog that has lots of growing left to do so experience of caring for larger breeds would be beneficial.’
