KYgrandma, I believe that my dog is also telepathic. He knows me better than I know myself, he seems to understand full sentences, and likely has a vocabulary of around 500 words, or more.
The reason I ask if it is possible for a dog to be an angel, is because I believe that angels are sent to us by the Lord at the times in our life in which we need them.
A while back I read a story somewhere about a man who was about to commit a mass murder. He was on his way, armed with many guns when he crossed paths with a stray dog. He stopped to pet the animal, and apparently it touched him. He said that he did not know that something could be so loving as this dog. He returned home and did not go through with his plan. I cannot recall what the story said happened to him or the dog, and I cannot find this story now.
It seems to me that our physical bodies are vessels for souls. I also believe that dogs have souls, some of them seems to be very advanced or old souls. If a dog’s body is also a vessel for souls, then I still wonder if it is possible for an angel to be in that vessel. I don’t know, it’s just something that I have wondered for a time now.
Angels have appeared in many forms throughout Scripture and, if the story you mention is true, an angel appeared in this form for that special purpose. The angel, I don’t think, stayed in that form as a dog.
To liken human souls, or angelic, as “being” animals smacks of reincarnation. I do not believe this is true.
