Hopefully you have found some way to resolve the situtation by now. I want to mention that a dog can either vomit or it can regurgitate. We think of these as the same thing but they aren't quite the same. A vomiting dog will heave; it sort of works at it and it's sides will heave. A dog that regurgitates more or less just opens its mouth and icky stuff comes out. I'm mentioning this because I have a dog with megaesophagus (mega-E for short). Mega=big and esophagus is just that. Big esophagus. Instead of being about the diameter of a thumb, Akaya's esophagus is more like the size of my upper arm. This is a problem because a dog's esophagus takes the food and passes it basically in a horizontal line from the mouth along the spine to the opening of the stomach which basically points upward toward the spine. It's not like with people where we eat and food essentially drops down into the stomach. If the esophagus is too large, the food goes into the mouth and tumbles down into the deep part of the esophagus and can't get to the stomach because the opening is above where the food went. To handle this, owners have to make their dogs sit in a completely vertical (beg) position during meals and afterward for awhile. Why mention this? I went for a year dealing with my dog "vomiting" during the nights once in a while. It became more frequent. Then on a vacation once, she repeatedly lost large volumes of undigested food. When home, she underwent tests and right from the start and x-ray revealed a giant esophagus with a two pouches. In Akaya's case, she was a very lucky dog in that her esophagus still had the ability to make wavelike movements to make food move from the mouth toward the stomach, but the food was not getting "up" into the stomach except by chance. She had a habit of lying with only her front half on the bed sometimes with back feet on the floor, and she loved leaping upward to catch a ball. I credit those actions with helping get food into the stomach.
The point is, she would wake in the mornings and "vomit" but I later learned it was just that the esophagus had held that food all night and when she woudl start moving, the food would flow back to the mouth and she'd essentially just spit it out. It had not been in her stomach and that means she didn't actually vomit. We would have a few days where she would seem okay and then one night or morning she would make 5 or 6 large puddles of food, slime or "stuff we couldn't label" that could be as large as a food in diameter. We refer to those as her regurg cycles.
Acid reflux can be a problem for any dog and seems to be a problem for mega-E dogs as well. Not only doesn't food get to the stomach, but the stomach makes acid and spits it up and out so that it goes into the esophagus and lies there. If it happens at night, the dog has that acid in it's esophagus during the night and will spit it out in the morining. Very often her regurg is mostly mucous or extremely slimey and hard to clean up.
To keep reflux low and help mega-E dogs handle food best, mega-E dogs eat 4, 5, 6 or more meals a day. Yes, that's a hassle. With a 95 lb dog that has to be hand-fed (four meals works for Akaya, luckily) and then has to be kept in a sitting position after each meal for 20-25 minutes. It's hard work but in Akaya's case, regurgitation cycles have been kept mostly under control and if she has a night or morning, or heaven forbid - a day - of issues, we know it's because she got a bit more food than she can handle, or the wrong type of food (no treats anymore) or we didn't have her sitting upright enough each time. Eventually, it clears out and we have mroe good days. Nights, however, are tough for her because she apparently has reflux at night (me too). Often I wake and go force her to sit up in a beg position for a bit.
In Akaya's case, a treat at night is detrimental. Of course, I didn't know that way back when and she got a treat every night to help give her stomach something to work on. Little did I know it was just sitting in her esophagus every night only to be spit out again in the morning in messy form. Now she has a last meal at about 8:30 p.m. and sits up for 25 or 30 minutes for that last time, and even then, we often have to let her out for a bit so she can spit out the acid or we have to sit her up so whatever is in her esophagus can "go down."
Mega-E can be caused by a couple health conditions but can also be idiopathic (unknown cause and therefore likely to slowly worsen over time - Akaya's case). If caused by other conditions and those conditions are brought under control, the mega-E sometimes can be somewhat improved or, I think, even reversed. Akaya's fortunate.
If your dog is not heaving, not working hard to get rid of stomach contents, but just losing contents with little or no effort, keep an eye out over time. If issues increase in number over time, or if your dog seems to lose weight, and you don't think the dog looks like it is heaving, you might want to ask your vet about the possibility of megaesophagus. I'm not mentioning it because I think your dog might have it but because many people have no idea this condition exists and live as I did for a couple years...just cleaning up what they thought was vomit...until their dog was seriously ill.
Also, Akaya is 94 lbs, takes one Prilosec pill every morning a few minutes before eating and then has one Pepcid (10 mg) 45 minutes or so before her last meal. This helps keep acid under control. For some dogs that vomit a little, that is all it takes to help them reduce or eliminate stomach troubles.
I hope your pal improves without much hassle at all. At this point, it doesn't sound like a huge worry. I just wanted to make you and others aware that this condition exists and you can be fooled into thinking it's just a dog vomiting for some reason.
