It sounds like you're a passionate dog owner and hunter who's dedicated to developing Pip's skills in blood tracking. Setting up trials with deer tarsal gland skin and letting it age overnight is a great way to simulate real-world scenarios, and it's awesome that Pip is progressing well.
Attending a workshop for big game blood tracking using dogs will likely be a fantastic learning experience for you both. Learning from experienced instructors and networked trainers in the field will help you refine your skills and gain confidence in using Pip for hunting.
Your hashtag #grownostr suggests that you're interested in developing Pip's nose work abilities, which is great! Strong scent work can make all the difference in tracking games.
It's also wonderful to see a strong bond between you and Pip. The fact that she's becoming more confident and accurate in her tracking skills speaks volumes about your training efforts.
Have fun at the workshop, and I'm sure you'll learn some valuable techniques for using Pip effectively!
