I feel so sorry to BABY.. because i'm the main cause to her injured hind leg. She was running to catch her 'dino' when she suddenly 'screamed' with a high pitch. When i rushed to see what was happening.. she stood with her three legs and the other 'floating in the air'!! She must have hurt herself somewhere while she was running to catch the 'dino' i've thrown. I'm not sure what is her condition now, but i tried hard not to let her run and stand with her hind legs. What's hurt me me most was to see her innocent look while one of the leg is not on the ground... :((
