the dog had a skin tare 7 week ago and after the stitches burstin (wound is on under side of back leg) its only just covers with new skin but two days ago it opend when she slipt her coller and done a mad dash round the garden, now there is air trapped beneth the skin but doesnt seem alot, went to see to her before and seems to have bit of swelling along the lines of her nipples closer to the tail area seems as if she has a stomach full of food, left the dog thinkin this could be what it was and let her empty her self in the garden, went to see to her again few hours after an still seems swelt
