It took about a week each day got a bit better , if it is a food intollerance there will be no quick fix , its the same as humans suffering with irritable bowl syndrome , sometimes you need to just be patient , and let the new food do the trick , i must say though we tried the canned royal canin to start with that didnt work after a week so thats when we were asked to put her on the hypoallergenic food ,
She could only stay on it for about 6 weeks cos being a pup she needed more from her food than the hypo food was going to give her long term , but once she was fine we weened her off the royal canin very slowly over a period of about 10 days onto royal canin labrador junior , she did well on this .
