Ok so here's the story... Ran the dogs the other day on icy snow because they had been goin stir crazy in the house. Been a long time since they got a decent workout. Anyhow- after bout half hour when I figured it was time to quit I noticed both their feets were bleedin well finally found bag balm here in town, coated their feets in it, kenneled em n went to a movie. Got home and let them out potty before we went to bed and my Lacey girl starts screaming bloody murder. Settled down a second and then did it again. Now she is my tough girl- would run herself to death play fetch just to win- sk I know it's gotta be serious... Anyhow checked her entire body over twice for any kind of reaction and got nothin. Let em out potty. Lifted her onto my bed and she shook for a few minutes like she does when she's really excited and then she calmed down and went to bed. Well she's been fine all day. Haven't let her run around or play rough with George. Little bit ago I walked into the kitchen and heard that scream again. She jumped down off the couch to follow me. I noticed she isn't putting weight on her back right leg. Checked pads again and they're fine. Perfect range of motion without wincing. Joints all moving fine. I dunno. Takin her in Monday and restricting joint or rough play. Thinking maybe a warm bath with Epsom salts... Not sure what else to do. Probly lookin at xray Monday. Just prayin nothin serious needin surgery ugh.
