Yesterday evening my dh and I returned from dinner and Mindy seemed fine. About 15 minutes later she was hobbling on 3 legs-holding her left back leg up. She wasn't running or jumping when it happened- she didn't bark or shriek- she just wouldn't put any weight on it.We thought we would see how she was in the morning rather than take her to the emergency vet which I don't like. Last night she didn't move at all on the bed- she won't walk on it at all this morning. I can't see anything and she doesn't act like she's in pain when I palpate her leg. She's never had any problems with limping before. I'll take her to the vet this morning and see what they say.
