Superstar Salman Khan has shared a photograph where he is seen expressing his "unconditional" love towards his pet dog.

The 50-year-old shared a photograph of himself kissing his pet. He captioned it: "Unconditional".

"Sultan" is said to be based on life of Sultan Ali Khan -- a wrestler who is faced with problems in his professional and personal lives. To get hold of the character in the best possible way, Salman gained weight and underwent rigorous training.

The film also stars Anushka Sharma as a wrestler. Produced by Aditya Chopra under the Yash Raj Films banner, "Sultan" is slated to release on Eid this year.
