Here's the addition.. not much.

"Well," the doctor said. "I think her leg is broken, and she has a tiny cut on her side. We'll take her in and put a cast on and stitch up that cut. Your dog will be fine." She said smiling.
"She's not mine." Amanda said. My heart sank. I so wanted to be with her, and live with her and her puppy. "But I will take care of her until we find her owner." she said, smiling at me. My heart lifted a little, but I knew that Jason would come and get me sooner or later.
The vet took me unwillingly into the back. She layed me on an even colder table and I jumped a little from the coldness. She put a mask on me and I soon began drifting off to sleep.

I was romping around with my brothers and sisters. It was a beautiful spring day and we were all outside again. Levi had just been chased by Jo and we were all headed toward Mom. We all got a few feet away and she began disapearing right before our eyes. We got closer and she was gone. We all looked at each other and began to cry. "MOMMA!!" Willow, Mika, and Mac all yelled. I stopped and sat down. I saw kids coming. "Run guys, RUN!" I yelled. We all began running and hid beneath the bushes. One by one they grabbed us all and took us away....

"Wake up, sweetie..." the doctor was saying. I opened my eyes and felt a sharp pain shoot through my leg. There was a large pink thing on my leg, which I assumed was the cast she had mentioned earlier. She scratched behind my ears and soon Amanda came back in. I thumped my tail on the ground as she neared.
