Actually I had it happen to me last night!!! I was sick my beautiful baby Chloe' feel outta my arms being a wiggle worm and landed on her side...she screamed so loud it was awful! I felt totally sick as I rushed her up to my vet, thankfully she said she looked good...no broken bones or fractures!!! She gave her some anti-inflammatory medicine and she seems to be getting around fine and acting totally normal but I'm terrified it will happen again and end in a much worse circumstance!! I'm constantly worrying whether or not she's ok because she's so small...she's only 1lb 7 ounces at 3 months and we just brought her home a week ago...I'm sure your baby will be just fine just keep a close eye on her and lots of puppy kisses!!! It was good that you took her to the vet so she could get the medicine she needs!!
