This question is about my pet dog. My 2 month old Siberian Husky puppy is infected with Ehrlichia Spp and she has liver problems too. Her bilirubin is at 1.07, AST is at 61 and Alkaline Phosphatase is at 380. My vet advised Hepamerz injection IV on alternate days for liver and Oxytetracycline daily for 15 days. But when the Stool Culture report showed E.Coli growth in her stool is resistant to Tetracycline, he stopped giving her Oxytetracycline 4 days ago. Now I am confused if it is necessary for Ehrlichia Spp bacteria to be resistant to Tetracycline just because E.Coli is. Isn't stopping the medicine totally would be dangerous for her? Opinions please. Thank you in advance.
