I have a 9 month old English Setter who frequently (2-3x a week) throws up bile around 3-4pm. She eats at 7 am, 12 noon and 6pm, a total of about 3.25 cups of food a day (above what the bag recommends but more aligned with what the breeder recommended). When I took her into the vet, they told me she likely had Bilious Vomiting Syndrome and gave me 7 days of Omeprazole. She then got some sort of unrelated GI issue and has since started vomiting bile again. I'm at my wits end and so frustrated. Has anyone had this issue and what solved it for you!? How much are you feeding your dogs and what food?

She is currently on Royal Canin Hydrolyzed Protein Puppy food, but previously ate Open Farm Homestead Turkey & Ancient Grains Dog Kibble.
