Here you go randy, a similar

Here you go randy, a similar protocol can be found int he gastritis chapter in the Curbside. But here is my go to empirical tx:

Helicobacter/Gastritis protocol

A clinical trial of Zithromax (Dogs: 5-10 mg/kg p.o. q24h. May increase dosing interval to q48h after 3-5 days of treatment), Metronidazole (10-20 mg/kg p.o. b.i.d.), Pepcid (0.5-1 mg/kg s.i.d.) and Sucralfate (0.5-2 g/dog PO) or Omeprazole (1 mg/kg p.o. s.i.d.) over the next 3 weeks along with a novel-protein or hydrolyzed diet with slurry feeding b.i.d./t.i.d. over the next 2-4 days and then increase to canned diet bid. Dry food should be avoided over the next 4 weeks. A recheck sonogram to assess GI improvement or progression would be ideal in 4 weeks.
