That's a pretty small and light ebt/greyhound. These are the ebt/greys I'm more accustomed to- Is the one in your pic possibly from england used as a lurcher for fast game? It's interesting to see how different roles will shape the same cross. The ones I posted have ebt/grey origins but were equally shaped by the demands of boarhunting, which perhaps didn't call for a dog quite so quick and agile as coursing game in the UK would. Mind you I think I've seen some boarhunting ebt/greys similar to that one, but the established lines seem to push out bigger dogs. Cool ridgeback x arab castanha, not a million miles away from laika really.
