Cowboy I get a couple things from your last post.
1. Just cause a dog was brought in doesn't mean they is gone be a deer found.
2. Good blood is subjective to who is looking at it
3. I go back to a above post I feel like the nose knows as far as what's dead or hurt or skint up.
Like Harold said they can sometimes go aways before they lay down and as a rule the further that is from the hit the less hurt they are
