I have to agree that animals have souls, and some even hang around us, if only for a little while!
I can remember when I was 4, we had a dog named Major. He would "make the rounds" at night, several times a night, to check on my sister and I, and Mom and Dad! We would hear his toenails on the floor and his tags jingling! One day, I woke up from my nap and heard my Mom on the phone with my Dad, telling him that Major had died! For several months after Major died, we would hear his toenails and tags as he made his nightly rounds!! Loyal and protective, even in death!!
I have worked with animals for about 30 of my 50 years, in shelters and vet clinics. I am a Vet Tech at an animal hospital. Sadly, I have seen TOO many "fur-babies" pass away, both naturally or with gentle, loving assistance. There is a poem called "The Rainbow Bridge", that describes a place where our pets go when they die. There, they are happy, healthy, and they play again like youngsters, while they wait for us to join them! What a wonderful place it must be, and what joy to be re-united with our pets!!
On August 30, 2011, the wonderful Doctors I work for, and I, had to help my 11 1/2 year old Golden Retriever, Little Bear Heart, cross the Bridge. He had a condition that causes the loss of use of the back legs. He was in pain and he was suffering, and he no longer had the happy "spark" in his eyes. It was tough, but I couldn't let him live in pain!! About a week later, I had just gone to bed, was listening to the radio, and had just closed my eyes. In my mind's eye (like a dream, but I WASN'T asleep) I saw Little Bear (standing on strong legs!) at my bedroom door! He was wagging his tail, with bright happy eyes, and had his favorite toy in his mouth as if ready to play fetch! He hadn't been able to play for a few months because of the weakness in his legs! It was as if he came to tell me, "Look Mom! I'm healthy and happy, and I can run and play, and I will be here waiting for you to come play with me again"!! I miss him and think about him every day, but I know that we will be together again at The Rainbow Bridge!!!! So YES, I believe with all of my heart that they have souls and even stay with us after death, even if only for a little while!
