Oh, those Spaniel eyes. They know how to get what they want!!!
We’ve a Working Cocker and have found when we put him on rice (mixed with a small portion of his kibble) when he has the squits, it can take a few days to clear. We also keep him on the rice for a day or 2 once they clear up to make sure he’s nice and solid.
I would say based on the weights you quote he’s on about the right amount, you do want to cut it down a bit when they have dodgy tummies, so as not to make it worse.
I wouldn’t overly worry, if he’s acting normally (well as normal as a cocker can be), eating and drinking about the same as normal, give it a few days.
Ours always gets hungry when he has the squits, he’s been clearing his system, so is bound to be more empty and hungry.
I would change from Bakers though. We feed ours Orijen, but go with the best food you can. As a rule of thumb make sure the first 2 or 3 ingredients are meat and there is no grain.
