Kip went to the vet again for a recheck on his clicking sound. Today we were able to confirm that the noise is coming from his right knee joint. The vet can feel the click there. So the good news is no inflammation, no instability, no pain (as far as we can tell), and he is acting normal. I showed the vet videos of him walking, trotting, and doing cavalettis, and she thought that all looked normal. The frustrating part is we still don't know WHY the click is happening. A common cause of a click sound in the knee is a meniscus tear. But normally meniscus tears are accompanied by pain and limping. They are also most common with an ACL/CCL tear. Kip's knee feels stable, so the vet doesn't think that's the cause. The vet said the clicking might be something Kip outgrows, or it might turn into a problem later on. Plan: several more weeks of restricted/controlled exercise. The vet is going to do some research and get back to me. If the clicking doesn't resolve, I may ask for a referral to a different vet for a second opinion. All I want to know is: Is something wrong? If so, what can we do? I just wish I had a definitive answer. Has anyone here had a dog with a meniscus tear? Any ideas on keeping Kip happy and calm in his crate/ X-Pen in the house? He gets so bored, and then he jumps up and down, and I'm scared that's going to make things worse. He has a kong, but it only occupies him for a few minutes. We go on gentle leash walks, play gently, have cuddle sessions, trick training sessions, but he still gets bored.
