Hellhounds?

Long story short, I'm trying to get back in touch with my clairaudience and in the process I've come across a hellhound(as confirmed by my pendulum). We're both having trouble communicating with the other, pendulum works but is obviously pretty limited.

I never even knew much about hellhounds until I made contact with this one, so I'm totally lost on how to handle it or why she's presented herself to me.

I've tried googling and scouring tumblr for lore and information but everything I've been able to find is either incredibly vague black shuck lore or very bias Christians.

So anyway, I was just wondering if any of you have any upg, links, or recourses of any kind that could be helpful in learning more about them, communicating, offerings, that sort of thing.

Thanks in advance <3
