Hi, I can help you with your question today
From what you are describing, I do not think that she broke it.
More often than not, animals with severe orthopedic injuries like fractures or dislocations will NOT put ANY weight on that leg
So even though she is favoring her front paw, since she is using it I am hopeful that it is just a soft tissue injury like a sprain.
Do you notice anywhere specific that seems painful or swollen?
