I'm asking this question because I don't know the answer for a Lacy, but do you really need "deer" blood? I would think that training a tracking dog would involve using many scents to teach them to track & find what you put them on. I literally taught my first GSP to hunt dead by hiding goldfish crackers outside and teaching the term "DEAD" to find them. Once we got on birds, he knew DEAD meant "search" and started finding birds no problem. I would think any kind of blood would work?
I've been talking to a bunch of Lacy trainers and they are telling me that beef blood will work. I bought a package of beef livers yesterday and plan on blending them up and mixing in a little blood that I drain off of my frozen venison and using it. All of those guys are telling me that will work just fine. Cant wait to get her on some blood this evening.
