Hi, yes change to a limited ingredient single protein kibble, a protein he hasn’t eaten before, I always recommend “California Natural Lamb & Rice” Large bites it has just 4 ingredients…. then if poos firm up, slowly add a new ingredient with the kibble, like an elimination diet, to see if he has a food intolerance or he may need a lower fat or lower fiber kibble.. California Natural Lamb & Rice is a low fiber kibble 2.5%max its worth a shot it may just work & its better then the vet diets… http://www.californianaturalpet.com/products/1181

When my boy was having poo problems he was put on vet diet “Eukanuba Intestinal” its a low residue, low fiber kibble, the fiber is only 1.7% there’s also “Eukanuba Intestinal Plus” but the fiber is higher at 4% like the Iams Intestinal, the fiber is 4% & Iams uses byproducts where Eukanuba doesn’t….

My boy has IBD & needs a low fat & low fiber diet, as soon as the fat % is over 14% fat his poos are sloppy cow patties.. if I add pumkin (high fiber) he does sloppy poos…
In time you will work out what works & what doesn’t, like you added fiber & it didn’t help, so he may need lower fiber kibble & a lot of kibbles are 4% & up, the only real low fiber diets are vet diets & the California Natural Lamb & Rice & Chicken & rice at 2.5%max fiber….
