Lindsey Savage Learning Issues: 1. How can the cranial drawer sign be negative when awake but positive when sedated? 2. Is any amount of cranial drawer considered a positive result or is there a threshold displacement before it is positive? (ie: is <2mm a positive test?) 3. Does a cranial drawer sign always indicate a cranial cruciate ligament rupture? 4. What is the normal stifle anatomy? (ligaments, etc.) 5. What diseases usually/have the potential to localize to the stifle joint? 6. Is the dog's current diet appropriate for her activity and body condition score?
