I would give his tummy a rest for about 12 hours then start on cooked chicken & rice although sometimes on odd occasions it can upset some dogs . I always have a pot of digestive powders in the cupboard , i have 7 cockers and swear by it, it firms up the poos cleans any unwanted bugs and soothes the gut!!! hope all is well soon, ring 01379 788170 if you needed the powders! k.
