She has had diarrhoea almost constantly for the past couple of months. She doesn't get urgency but she goes every time she is let out, and every 10-15 minutes while out walking. it varies in consistency from porridge to water. After several trips in quick succession she can have blood (bright red and on the surface of the stool) and just lately she has been yelping when going. It is not infectious, as neither my mum's other dog nor mine has had any problems. They have tried different antibiotics and it seems to improve but then as soon as the course finishes she goes downhill again. Anyway, they are now investigating her for IBD. I didn't even know animals could get it!
