Hi there, needing more advice :-) my 8 week old labrador puppy TOMMY who is currently on antibiotics for a touch of colitis and has had his food changed to scrambled egg, mash potatoe etc to prevent more stomach irritation has just had a stool which was very runny, no blood which is a plus however there was tiny (cous cous size!) hard white lumps, dont know if this is worms or just because weve changed his diet? they arent moving and he was wormed with drontal by the breeder on the 30th of march and is not due till the 15th, Would appreciate any advice, thanks

Have you been giving him boiled rice? If so, that's what it is - you need to boil the rice for much longer than you would to serve to your family (where the rice grains are still separate), and with much more water. Those white bits would be the undigested centre of the rice grains.

Thank you jeangenie you've put our minds at rest .
