There is something in the diet causing this. A dog that is up all night gulping and licking is being fed wrong. Please try a single protein and carb. If the reflux calms down then stick with that for life, forget variety. If it doesn’t calm down, change it to another protein and carb. Don’t deviate, even with treats, until you get to the culprit. Those berries might not be helping either, I have one dog that got acid reflux from a cranberry supplement (among other things). Be patient and good luck!
