ive recently got meself a 11 month old bullmastiff cross greyhound and a was wondering has anybody else got one? i wanted a bull x and there was a few quality staffy crosses but they all got snapped upbefore i got there. then the mastiff cross came in and i had him, hes a good guard dog but will he be a good worker? hes quick and strong but will he end up to heavy? last time i had him weighted he was 9 months and he was 30 kg. hes a 50/50 cross. cheers.
