I have a similar, but much milder case with my dog, a terrier. I am stumped. I did look up food that causes gas on a site called Puristat and keep that in mind when feeding Joey. I have GasX if he seems to really be gulping a lot or belching, as he does on occasion. I don't feed him anything after 7 at night. I'm looking into whether our bedroom is too dry, as he swallows a bit throughout the night, and I wake up with dry mouth.
One comment to the person who's feeding grain free but also using Greenies. The last I looked, Greenies had a high wheat content. If a dog's stomach is sensitive to wheat, I would not use Greenies. Maybe wrapping the pill in a bit of cheese would be a better alternative.
I have not run across seizures as a possible cause. That is interesting. I did, however, run across a woman whose dog had major gulping at night and it finally went away when he was placed on an antibiotic for a month. (I'm not sure what kind of infection the vet was treating, however.)
I sometimes wonder if Joey has a bad tooth, or some kind of dental problem. Pain for me gets worse at night (perhaps our body temp is higher? not sure) and perhaps a lot of worsening of symptoms occurs at night because of that.View Thread
