After we lost our soulmate (Quasar) we tried and tried to focus on the dog we had left, but two weeks after our boy passed I knew some little one was coming to us. I just felt it. I looked on petfinder and put in Australian Shepherd and this shepherd pup with a natural bob tail popped up and I gasped and said "that's our dog". I tried to talk myself out, but nope. He spoke to our hearts. After he came, I presented to him Quay's 5 stuffed toys and he grabbed them one by one and took them to the crate in the order of how Quay preferred them. It's then that I knew Quay sent him.
Keep an open mind. Sometimes the timing is a bit off, but the dog is right. Listen to your heart and you will know.
