hi,out walking today my 10 mth old girl chases a rabbit next thing there is a loud scream.When l get to her she is falling all over the place and then callapsed.I got her to stand on three legs,but she wouldnt put the right hind down.Took her to the vets straight away,she then put the leg to the ground but not weight bearing.So she seems to have control of the leg so l dont think theres nerve damage.The vet hopes it is torn ligament and not a fracture.She wll be X rayed and operated on tomorrow.l here this type of injury is very common,if anybody has had the same type of injury to there dog could you please let me know.thanks Ann
