Hello HelloWorld18: Thank you for sharing your story with us. Many years ago I had a dog I loved very much. As she got older, she developed a patch of skin on one side where fur no longer grew. I was still in my early teens. My parents were poor. I don't know if they didn't think it was worth taking her to the vet, or if they felt they couldn't afford it.
Over time, "Sandy" became visibly more ill. Eventually my parents decided we had to take her to the vet. So on the day we were to go, I went outside to fetch her. (It was a bright sunny summer day.) I found Sandy laying on her side in the sun beside the house... dead. We lived out in the country. And so we buried her behind the house near the woods she loved to run in. I hope she didn't suffer. I still think of her to this day.
My condolences...
