Glad that vet visit went well for your boy and that his weight is normal ;) It's good that you've been recommended a diet change - I know that Wafcol Salmon and Potato is often recommended because it is basically a novel source of ingredients compared to many other complete foods hence a good port of call for an "exclusion diet". Exclusion diets are designed to see if a change away from common ingredients relieves symptoms and can save the expense of perhaps allergy testing certain foods for dogs who have continual GI problems so I'd imagine that is why your vet has suggested that brand in particular.
Can I be so bold as to make an additional suggestion which is basically crucial to the effectiveness of his diet change :rolleyes: don't under ANY circustances give him ANY other type of food, dog or human, neither treats, rawhide chews, pigs ears, bones - nowt - and be hyper vigilant that he has no scavenging opportunities elsewhere :D
If you don't see any improvement in his stools within the first couple of weeks, I'd suggest you go back to your vet and have the faecal sample done and also bloods tests to rule out other potential causes such as pancreatic malfunction.
Very best wishes and gentle hugs to your lovely, lively guy ;) Teri
