Boiled rice can be frozen successfully BUT given how little a puppy of that age should need, I'd only make enough for a day's feeding, if you use it at all. Rice and poached chicken breast, or white fish is normally suggested, BUT I tend to avoid rice if I can because it goes EVERYWHERE and when I've had to use it, I've spent a long time picking the flicked bits up off the floor. If this is just an uncomplicated tummy upset, try adding a little natural, unflavoured yogurt - if you can source goats yog which is more available these days, so much the better. And yes, use the stock the chicken/fish is cooked in (just a little) to help with hydration. No salt!!
