THIS is the unbelievable moment a mother dog who had lost almost her entire litter takes her dying last pup to the vet to be treated.

Another of her litter had recently been saved by kind passersby who discovered it struggling and rushed to find help.

Amazingly, the mother brought her last pup to the very same vets in Istanbul, Turkey, that its sibling was already being treated.

Footage shows the exhausted mum trotting through the rain to deliver her struggling pup to the surgery – where she seems to know it will be helped.

The mum drops her baby off right by the door where it is soon noticed by a vet on duty who comes out to investigate.

It is quickly realised the pup is horribly sick and suffering from hypothermia, and it is rushed inside for urgent treatment.

Inside, the vets waste no time in administering injections to the puppy and blow-drying its soaking wet fur.

Medics found the pup to have a dangerously low heart rate and had to immediately place the little pooch in intensive care, meaning the mother dog had carried her baby in just in time.

Veterinarian Baturalp Oghan revealed that all but one of the rest of the young litter had tragically perished.

Vets simply named the heroic dog “Mom”.

Mom refused to leave her baby’s side, and is seen coming to check on it whilst it is being treated on the operating table.

Dr Oghan explained that her milk was insufficient, but the clinic were supporting the puppies with additional food.

The dog and her two remaining pups are now being cared for at the clinic where their health is thankfully steadily improving.

Heartwarming footage shows the fluffy brown pup slowly coming back to life and wriggling around.

It is later seen tucking into Mom’s milk on a blanket after being reunited with its only surviving sibling.

Dr Oghan recalled just how touched he and the clinic staff were from the mother dog’s determination to save her puppy.

The vet staff also all hope to find a loving home for the canine family once they fully recover from the ordeal.

Dr Oghan said: “Everything is going well so far. The treatment for both the puppy and its sibling will continue for a little longer.

“During this time, we are not accepting visitors due to their health.

“The mother dog is recovering well.

“Her story has intrigued so many people, she’s a very intelligent and caring dog.

“It shows the love that a mother dog has for her puppies.”
