This was my first bull. Hit the off shoulder on a qtr. away shot, no exit hole. Blood ran out within 100 yards and we tracked him another 300 or so yards from last blood but lost the trail. The G&F officer told me opening day in a conversation, he knew of a dog that blood trailed and to give him a call if needed, not thinking I'd need to. After we lost the trail, I remembered our chat and headed for cell service as it was pretty warm and was worried about wasting this animal, which we all know is the worst scenario. And it was Daisy to the rescue! She was awesome, as was the game officer also.
As for the regs on it, dogs can be used to trail a wounded animal but not to chase. Once the animal is found, if not dead, the dog must be pulled back and the hunter proceed on to finish the animal.
Thanks again to Daisy and the G&F officer for all the help!
