I glad to hear the xrays were normal.
I forgot this is her front leg. Justice had a lot of stiffness in his left wrist(carpus) for a long time. He tore his flexor tendon 3 yrs ago on Halloween. He recovered well but for the longest time, he would be fine and then too much jumping/running and then limp. It was like this on and off for 2 yrs.
What it came down to was too much resting and then not enough strengthen/conditioning. Like the weekend warrior syndrome. He tends to do a left leg lead so that was always the leg hitting the ground first so that aggravated it. I used to be afraid to let him exercise because I was afraid he hurt himself. It just kept the cycle going.
I think it is a good idea to rest from agility for awhile to let things calm down. NSAIDs as needed. Acupunture would be great. There could even be little tendonitis going on and from researching Justice's issues I found out not too uncommon in shelties.
But hen when you start up again go really slowly and build up muscle conditioning. I found alot of good exercises on a DVD called Strengthening and good ideas for stretching before exercise with Stretching DVD. Both can be found on Clean Run.
It addition the DVD exercises, I did exercises in which I walked Justice in circles right and right to encourage lead changes and get him to change leads. I did 2x as much to the right or right lead as the left. He now will use the right lead more naturally. Walking on the treadmill help too. Peanut ball and balance disks are great too to build core.
My thoughts are with Chloe and you in trying to resolve this. Good luck trying her quiet and not jumping or running

You might want to hog tie her now.
