My Little Puppy Fell On Her Side. My dog fell on his side after jumping up about 4 feet for his toy. My pup will get done playing then everytime she’s abt to go to sleep she lets out this big old sigh or little huff as if she just got done working.

It may be that she has simply bruised herself or damaged a muscle or ligament. Panosteitis is a developmental disease that affects young, large breed dogs. Back to my story…fortunately for my friend his dog received the proper diagnosis.
