How accurate is this test when the dog is sedated? Can it show a partial or slight tear? I have a dog with mild rear leg lameness that has persisted over a week now with crate rest. He seemed to get better after a couple of days but it flared up again after I let him have more activity in the yard this weekend. X-rays o the hip didn't show anything per the vet. The drawer test showed nothing either. I assumed a few days of crate rest and all would be good if it was a sprain/strain, muscle pull or what not. How long should I try crate rest before we head back to the vet. How long should a more minor leg injury take to heal with rest. For what it's worth it happened inside on slick floors I believe. There was no indication of injury until he had been inside sliding around the den. I'm assuming he could have pulled something or hyper extended his hip given that he can't keep footing worth a darn in my den. Any input?
