I honestly have never dealt with either so I'm guessing by other peoples pictures and descriptions. She/he was walking with a limp with the bad leg slipping out to the side and the center of the foot arched up a bit but was walking on the foot. When she stopped she would rest back on the hock. Wish I could figure out how to post pictures from my iPhone. The next day the leg was still a bit to the side but definitely better, limping less and moving faster. The foot it less arched too. Thank you for your help!
