my mum's dog (a medium/small cross of something or other) is 7 and has arthritic spurs, has done for a few years, poor baby :( . she is on rimadyl but every so often, once a week or so, she refuses to eat in the morning, gets the most LOUD tummy grumbles, then she trots off to the garden for half an hour, eats a bunch of grass then comes and eats and the grumbles disappear. any ideas why these grumbles happen ? they really are loud, u can hear them from a few rooms away (with the doors closed !) :O
