I have a couple of questions. How much blood can a deer lose and keep going? If I hit the deer in the front shoulder do they bleed quite a bit but live through it. This is my first archery deer. I have gun hunted for 24 years. Last night about 5 minutes before last shooting time I arrowed a spike buck. I was on the ground and he was 20 yards away about broadside. When I shot I heard the arrow hit and I could see what looked like about half the arrow sticking out. He took off like a rocket with his tail high into a field of standing sunflowers. The shot looked maybe a bit high and a little forward. Maybe more high than anything. I've replayed the shot in my head a hundered times I'm just not sure anymore. I gave him a half hour before I tracked him. I found blood just a few yards away from the shot. I found about a foot of the arrow (the broadhead end)about 50 yards away.I never did find the nock end of the arrow. Still in the deer?The blood was bright red and fairly easy to follow. I had some snow cover so It made it much easier.I followed him for about a 1/10 of a mile and decided to wait till morning to keep tracking him. I started at 7:15 this morning I found a few spots where he had been standing and where was a real good spot of blood almost a small puddle. He bypassed a cattail slough to go across wide open country on his way to another huge standing sunflower field. When he went across some tall grass there was blood smeared about 4 feet high. In some areas it was sprayed about 9 feet. I followed good blood for about a mile then it was harder to find. Then about a half mile later I found better blood again. I did find before that what looked like a clot of blood on the ground. this went on for about another half mile. What I'm thinking he started clotting then it broke free again. Then it was pretty sparce for about a 1/4 mile. I jumped a deer in the flowers which I'm pretty sure was him. All I seen was a flash of white It seemed like it was moving pretty good. I found where he had lied down and where I thought where the deer jumped up from. There was some wet blood in the bed maybe 1/2 of a teaspoon total. This was 16 hours after he was shot. I found a couple of small drops away from the bed and in the general direction of travel of the jumped deer. I looked for about another hour and couldn't find no other blood sign at all. The sunflower field was about a half mile by 1/4 mile. I'm just sick of losing him. I don't know what else to do. I tracked him for over 2 miles now I can't find any sign at all. Is this common for a deer to go this far? What are his chances of surviving? Thanks for the advice and help..
