Ask your vet about Pepcid (prn) for acid reflux.

Re: “I heard in the case of acid relux, no grains are allowed and only low fat food”.

Not sure about this, please confer with your vet.

My friend’s dog has acid reflux/sensitive stomach issues and is doing well on Nutrisource chicken and rice (dry) as a base with a little boiled chicken mixed in and a little water added to the kibble.

I would stop searching the internet for answers, if your regular vet hasn’t been helpful within a reasonable amount of time consider consulting a veterinary internal medicine specialist.
First, see if you can work with your vet, additional testing may be indicated to get to the root of the problem, see what he recommends.

PS: Consider a prescription food if your vet recommends it, at least till the dog is stable.
