Yes I remember that first pass that guy and I recall someone else was really getting to you.
Your dream reminds me of something that occurred when I adopted my dog 15 yrs ago. SHe was the only dog in the shelter tha did not bark or whine when I entered. She just stood in the very last cage and looked at me as if communicating telepathically.
Anyway I was compelled to adopt her even though she was not a full bred husky that I wanted. She never barked or howled but made a weird kinda modified guttural intonation. Several months later she began shedding her hair and I found a large thick rubberband around her neck and throat. It was at the skin and the skin had started to grow around it as when I pulled it off it created a wound. She was so grateful and began to howl like she should! I find it interesting as my throat seems to my area also that I have problems with.
Anyway yes the wound... allowing might make it necessary to let the puppy die or maybe not....-the key being to just let it.... Allow it to take form. Anycase you know the outcome. I know you are already a healer who has transcended the wounds to help others.
