This is going to sound really paranoid but this evening I took Nads out to play since she just woke up and was full of energy. So I grabbed her tug and bite pillow and headed out. I let her pick which one she wanted to play with first and she chose the pillow. We were playing less than five minutes when I told her to 'out' she did and as I lifted the pillow up to carry it she leapt at it unexpectedly and actually got up to my shoulders but she was unable to get a solid grip and she twisted in the air and landed hard on her side with a loud yelp. I immediately dropped the toy and rushed to her, she got up and was quite shaken. I grabbed the toy and hung it on the "toy tree" so it wouldn't be a distraction while I looked her over. She seemed ok but her right hind seemed to swing in under her belly. She wanted to continue playing but I called it a day and went in to get my dad's opinion. He said she looked fine but I don't know I feel bad and am worried I just screwed something up. I didn't mean for her to jump so high.
