My 5 year old boxer has the same gulping condition, initially investigated as a gastric/acid reflux issue but after seeing a Neurologist in Sacramento at the VCA, and doing a lot of research, changing her food to no avail, we have diagnosed the issue as complex partial seizures.
By process of elimination we realized that POTASSIUM BROMIDE, a low-dose, low side effect anticonvulsant medication, entirely stopped these episodes. I caution that over time she steadily develops a tolerance to the med and we have to up the dose every four-six months or so. The neurologist said we may eventually move to stronger meds like phenobarbitol but it has been over 1 year and she is still on the potassium bromide. When she starts having minor episodes, as opposed to the hours long, all-night epidsodes she was having, we make another appointment and up the does by a couple ml. She is currently on 5 ml/daily of potassium bromide.

Hines is doing well preventing these episodes with a med call Zonisamide, which my neurologist said may be an option later but wanted to start with the mildest type of drug which is the potassium bromide.
Hope this helps, we were so heartbroken watching her have these episodes, she would lick the carpet incessantly then hack up hairballs, feverishly eat grass, and eat strings out of our shoe laces; this is a dog that is not destructive at any other time.
Go to a Neurologist or specialist to try the medication, it is inexpensive ($60 for a 2-3 month supply). We saw several general practice vets who were entirely unequipped to diagnose the condition, to be fair, the neurologist was a bit skeptical when I showed him my research as well because it is such a rare and uncommon type of seizure manifestation.
