So cool that you can share all of that!
The current vet I am using suggested that I go to a specialist in my area who I believe she called an internist but it may be a digestive specialist.
She is the one who said that the specialist could do the barium study and ultrasound, it may have been a guess on her part but I am so glad to know that if they offer one, I can feel confident refusing. I have the number and haven't called yet because Dezi isn't showing any serious signs of distress at the moment.
A scope scares me, she is only 2 3/4 lbs. My vet said the specialist may not even have a scope small enough. That scares me more. I may research ulcer treatment and see if it is an option without the scope. Not to mention that between my two girls, I am in for over $1000.00 in the last 4 months. Routine puppy stuff for Cassidy and emergency stuff for Desiree. I could use a break.

What can a barium study show, since you are an nonobjective opinion. I always feel like a bad person if I decline a test but they are sooooo expensive and unfortunately the vet's office is $$$ motivated.

Thanks so much, I really appreciate all your help.
