Due to an unfortunate dose of heavy poaching at my shoot, I have run out of blood I had stored up for tracking training my bmh.
I spoke with the local butcher who informed me they are no longer allowed to use blood in their black pudding etc but have to use a concentrate instead. Although I can get a bit of blood from him from draining an ox heart for example it is not really enough.
I have heard of dry concentrated blood being used. Could anyone please recommend me a place to order from / product so I can continue to train my dog up.
