Hi Ruth,
She needs an Endoscope + Biopsies ASAP, I bet you she has Helicobacter Spiral bacteria, this is why she is eating sticks etc .they get BAD acid reflux & pain across stomach.
My boy has IBD & was eating cat poo, plants etc, I asked his vet to do Endoscope + you need the “Biospies” some vets dont do Biospsies, then she needs to be put on Triple Therapy meds for 3 weeks, Metronidazole, Amoxicillin, Omeprazole taken every 12 hours with a meal, then when meds are finished you continue with 1 x 20mg Omeprazole in morning.. I just gave 1 x Omeprazole wile on the triple therapy meds feed a low fiber, high protein, low/med fat low carb food best Gluten free..

Have a look at “Wellness Core” Large Breed dry food it has Probiotics easy to digest… instead on the R/C Gastrointestinal formula.

I have to go bed, (Australia) I’ll post more in morning if not busy… are you on face book join this group “Dogs with IBD Holistic group” I’ll see you there hopefully, really good help.. https://www.facebook.com/groups/292537937935806/
