How poor my dog!

Yesterday, I took care of my dog all day. My dog got a neutral operation 2 days ago. A pet dog needs that operation. She got a period one time. When it came, she became nervouse and got stressed, so I decided to do the operation. During the operation, she slept deeply. When she waked up, she yelled with pain. I was astonished at her scream. It was difficult to see her pain for me . I regret the operaion, bu I thought that the operation was for her future happiness. Anyway, she couldn't eat anything and dhe laid in bed-clothes all day. When my dog ate mixed food yesterday, I was delighted.
