MY RB beagles gums used to bleed when she ate bones,but its not a big deal.She was older so we had to keep her teeth in good health,so they didnt Rot Is he older?? My beagle was around 10-11 years old when he gums started bleeding when she ate bones,i dont think its nothing to worry about,unless its GUSHING out blood ,then that wouldnt be very good
