I am so worried about her. While I was grooming her today she jumped off the table. Something she has never done before. Later this afternoon she was limping and couldn't put one of her back legs down. I phoned the vet and they said bring her in. After examing her they suspect a cruciate ligament injury, and have kept her in to give her pain relief through the night and then exrays in the morning. I am devastated, can't believe it, and just hated having to leave her there. She is not a young dog and has arthritis in her back leg. Not sure what to expect if she has to have this op. I feel terrible, I am just praying that the exrays show it's just her arthritis.
