I know how scary that is, when we first got Samson he fell backwards off the couch and couldn't put any pressure on his back leg, I thought for sure it was broken although he didn't cry when it happened or when I touched it. we waited about 30 minuets and he still wouldn't put pressure on it so we had to take him to the after hours vet. He just spained his leg and was on bed rest for 3 days. this wasn't too hard because he really wouldn't get out of bed anyways. it was very sad!
Today my puppy Harley took a flying leap of the side arm of my couch onto the tile (the doorbell rang and he had to go see what was going on), he made a made dash to the front door and then realized he was hurt and whined and whined. I thought he was really hurt but as soon as the contract workers came into the home he ran to lick them.
these little ones can really scare you!!!!
