This is the tear-jerking moment a dying puppy mustered enough strength to wag her tail in delight as a group of rescuers approached her in the streets.

The poorly pooch was discovered by members of Animal Aid Unlimited in India suffering from canine distemper, a viral disease that causes fever, coughing, and catarrh.

Abandoned by the side of a road in Udaipur, the weak dog can be seen wagging her tail as the video maker and team of rescuers approach and give her some affection.

One man strokes the starving puppy, which is covered in sores and pants heavily, before lifting her gently into the air and carrying her to the van.

A vet later attached the animal to a drip and for 14 days the team treated the pooch for her distemper with antibiotics and IV fluids.

After much supportive care the dog soon began to start eating and walking again and was able to spend time socialising with the other recovering animals at the centre.

The dog was captured on camera playing at the animal shelter in Udaipur, Rajasthan, and receiving some much-needed affection from the staff members.

Looking much stronger and with a genuine smile on her face, the pooch wags her tail with a lot more vigour in the second half of the video.

Since appearing online the footage has been viewed more than two million times and numerous people have heaped praise on the charity workers.

One wrote: 'Wow. I think a few minutes later and she would have been dead. Thank you so much for rescuing her.'
