I'm still trying to figure this out, without the use of Pepcid. I'm using trial and error regarding what late-night snack combo works for Bella. Tuesday night I gave her a quarter of her kibble at 11:30PM. The next morning at 7:00AM, she spit up bile again, along with this chunk of something. It looked like a big chunk of mashed up hardened dirt. I have no idea what it was, but she could have swallowed anything!
Anyway, last night I gave her some grain free snacks (I forget the brand--I got it from Petsmart--it comes in a tube) and a rice cake. This morning when I woke up, I gave her another rice cake. No vomit this morning!
I also purchased Fromm's grain-free bisquits from Amazon. They arrive today. I'm going to start giving those to her at night and maybe another one in the mornings. I hope that keeps her tummy settled.
