Thank you guys and girls
Your right Stormyboy, most have thrown towards the Bull mastiff side, large heads, necks and shoulders, with short broad muzzles. Theirs two that are looking slimmer, with slightly more nose to them.
I believe they'll probably turn into slimmer Bullmastiff's rather than large muscular Lurchers.
There's some photo's and a video in the Working dog health and training section. Haven't taken any more recent ones yet.
Cheers again
Luke.
