Hello to you, and your dog, I raise and breed German shepherd dogs, currently I have 6 and they are a handful dealing with them every day, but this one girl, I kept her from birth, her mother was straight from Check Republic, any way she is 3rd generation, a beautiful sable 115 lbs, her name is Aja, and 5 years old, through the years she would go with me to put corn out, never was exposed to deer that were shot, blood any of that I kept her in her kennel while recovering the deer, sure she watched as I drug the deer past her and after dressing it out she would investigate the guts and all in the 1/2 barrel, this year was different, my 1st kill of the year she was on the porch with me, the dog does not like gun's, she lays down behind me when I'm gonna shoot, anyway she was there for the kill, and after I shot she ran by me off the porch and to the corn pile I shot on, I'm watching her, as I'm walking towards the shot place, she smells all around and into the woods she goes, the deer dropped 15 to 20 yds from where I shot it, when I got there I was amazed to see her attacking the deers neck and then to it's rear end, these were real attacks, since then every deer I have shot she has been a part of the recovery, same scenario every time, some are further in the woods and some aren't, but the last 8 pointer I shot last Friday wow!!! 300 yds to the corn pile, after the shot, Aja was full bore through my field, down the shooting lane, to the right she goes, when I get there she's a good 100 yds deep in the woods I'm looking around no blood no hair, but I'm watching her, I knew she was on the buck, 25 yds I found drops of blood, and then a real blood trail, Aja started this high pitched bark, never heard this sound out of her, she was back n forth having a fit, well the deer jumped a fence she couldn't get over it, clearly there was blood on both sides, and I found a tree across it, that she could get through, now we're 250 or 275 deep, blood stopped, but she keeps getting it, we come to a huge wide thicket, vines, laurel, bushes, around it she goes twice, then she stops nose in the air to the right nose in the air to the left, stops, and straight into the thicket, yes now the attack is on, deer was laying there dead, is this normal for my dog to know all this???
