Sounds all too familiar in my home! I always feel worst when I have thrown the ball that lands the injury! The other day my little male thought I was going to throw a toy for him and turned to chase it (I wasnt even thinking about it!) and he missed the steps and took a huge leap off all three of them, twisted in the air and somehow landed half on his feet. No injuries besides his ego! I feel even worse when I throw something wrong and they run into a door or couch trying to get it
My little female doesnt worry but the boy is a real sissie and comes crying to mommy for kisses
