Great Grandfather's Collection

[Robb0124]

Hi all. My great grandfather was killed at La Somme in 1916. Before he passed he collected 100s of British and Canadian cap badges. Some of which I am unable to identify still. I'm hoping someone out there can help me identify them.

This is one of the badges I can't identify: A small brass badge that appears to be a leaping or running greyhound type of dog/animal. Can't find an image online to match it unfortunately. This is a photo I took. Thank you for any help or guidance.
