"Remembering Ruby, a star of our bomb disposal squad, whose contribution to the department are 'impawssible' to match!" wrote Mumbai Police on Twitter.
Trained by handlers PC Naresh More and PN Sandip Shyatyapa, Ruby played a crucial role in detecting 41 cases.
"One of her most important detection was a brutal murder case in Khar East in 2015. She led cops to the culprit just by smelling a slipper," said Mumbai Police in its video tribute for Ruby.
