yes my collie has a similar trait think its the rounding sheep aspect coming threw.
saying that as he is geting older he is more full on straight down.he also wouldnt pick a rabbit up out of its seat he would wait to see which way it was going first .so id say its the collie ,i dont no in what way the deerhound works hows the pups
the pups are coming on great, cant wait till next year tho to get get them out running
