Hi. I'm sorry to hear about Reese. Angel was gagging on and off after I stopped giving her dog deli meat between her breakfast and lunch. The last time she vomited was on Sun., and she vomited quite a bit of yellow bile. The other times it was only a little bit. After the last incident, I gave her some rice but she only ate that and not the kibble. Therefore, I've been adding Nutro soft food (canned) to her breakfast and dinner to make sure she eats. For some reason she won't eat the kibble all the time by itself. People on the forum told me it was acid reflux. I was told the medical problems could be pancreatitis or a liver shunt.
Here's my post on this subject:

Please let me know how the vet visit goes and what the vet says.
