I had a pup who regurgitated water all the time.....they did a flouroscopy on him to rule out megaesophagus. He did have motility issues but it was some kind of issue with the nervous system....food was "seen" and the esophagus worked; but water was not "seen". He was put on numerous meds and did improve over time.
His chest rads didn't show anything....

Back to the diet. If IBD was diagnosed, I am quite surprised the vet didn't change that diet. You don't always see symptoms on a daily basis with IBD.... and food, specifically proteins, can definitely cause issues. You are giving three proteins....if you are giving them at different times, you might want to take note if perhaps one of them is causing these issues.

Another thing to consider. Has she had bile acid testing done? I had a pup who had occasional issues with regurgitation of his food after he ate.....it took some time before he was diagnosed but he had a liver shunt! He was an adult ... sometimes they don't have the typical symptoms of a shunt and it is entirely possible for them to have them into adulthood. He had surgery to correct the shunt ... he did also have IBD so was put on a hydrolyzed diet. He was about 8 at the time and lived to be 15.

I have never heard of regurgitation being a normal part of digestion. I need to look into that one.

One of the meds the one pup was put on was Cisapride. It helps with motility.

I’m sorry I wasn’t clear about that. Her diet was changed. This is the 4th brand of food that she’s been on, and the only one that has stopped the diarrhea she had. The proteins she is on are the lowest three protein flavors offered by this brand.

She has not had bile acid testing done. I’ll ask her vet about that, too. The ER vet mentioned liver shunt last year, but I think (if I remember correctly) that was ruled out based on symptoms & labs. I could be wrong though.

Here’s a good general article on regurgitation in dogs.

If your dog is generally acting normal (active and alert with no signs of pain) and isn’t losing weight, I would guess that the cause is benign (eating too fast, a mild hernia, etc) vs dangerous (cancer, megaesophagus, etc), but it’s still a good idea to investigate it fully, just in case.

A lot of vets think there should be symptoms and elevated liver enzymes for there to be a shunt.....not true.
Here is a link about my Teddy who I mentioned above. The size of the shunt is what is crucial...if it is a smaller shunt then some of the blood still goes through the liver and is filtered.

Teddy never had ANY elevated enzymes and was tested yearly prior to being diagnosed with a shunt.

Bluebells, she is acting totally normal otherwise... playful, sleeps well, normal weight. Hopefully it’s just eating too fast and not something more serious. She didn’t regurgitate her dinner or her breakfast (since posting this).

ladyjane , thank you, I’ll read Teddy’s story. Thank you for all of your help.

There used to be a great article on this on the University of TN's website. It was a brochure written by Dr. Tobias. Apparently it has been taken down...I was trying to find it to share with you.

I found this playing around on Google. Is it similar to what you’re looking for?

Yes, that is it. I called UT and they said they are updating their website...that it just started today. So, it will be there again.
Thank you! It is a great brochure.

It has been forever, so I’m trying to remember...but my Yorkie did this. She had the whole list of GI problems. She would regurgitate randomly, including water. We used Reglan to get the stuff on her stomach faster. Whatever was irritating her either stopped or the Reglan gave her esophagus a break. No idea really. I do remember she was on a powdered med once and it made the regurg terrible. I had to manually fill capsules so the powder didn’t touch her esophagus. 🤦*♀️
