Poor dear, It's hard to tell what is going on with the leg just yet. When Ellie was attacked in May it turned out she had a dislocation in her foot (she too was laying down) but it wasn't life altering once splinted and healed. Deal with the shock and stress first. Do not delay in getting her to a warm comfy safe quiet spot if she's still not been moved. Ack - I just realized you said the attack was 2 nights ago!! JJ
