good luck mate,been around greys 24 years track dogs,had kennels for 16 dogs and worked in a kennel with 36
so i know a bit flaped all over as well,well bred out of maldini but still dont make it run,
good luck mate but theres loads on data,field work is different to track work and for 200 pound carnt be very fast,
200 in the greyhound scene for a track dog isnt very fast just doing gradeing time,
if hes fast i know a trainer who will have him,but i doubt it
