Hi Vanessa, when I first rescued Patch he’d clear a room, it was awful…I put him on a dog probiotic & changed his food… have a look at the Wellpet Range, they make “Holistic Select” & “Wellness” kibbles & wet, the Holistic Select has a grainfree Adult & Puppy health Salmon Anchovy & Sardine meal or there’s Deboned Turkey & Lentils, maybe he cant handle the high protein so pick a kibble with a bit lower protein….but the Royal Canin is full of crap & probably the same price as a good quaility kibble, make sure you read the ingredients when picking a new kibble & pick a kibble that has different ingredients to the Blue Buffalo cause something is giving him bad gas which isnt good..also try some wet tin foods aswell, kibble is over proccessed & harder to digest, even some nice home cooked meals or raw.. he’s a link to the Holistic Select range
