Charlie was diagnosed with erlichia plathys one month ago, was on doxicicline for 25 days 50mg a day, after that he ha lilltle so the Vet stop the medicine. During the treatment we mixed his food Royal Canine poodle mix with a spoonful of science diet a/d for him ti eat. 5 days ago(same time we stop the antibiotic) we stop and tried science diet puppy can with his kibble, after 3 days he did not want to eat and started vomiting the water and foamy stuff. The Vet its stump and does not know what to think, he has him on nausea medication and told me keep trying just his dry food, I cheat it and mix his food again with a/d and he ate!. We are concern about what to do and what to feed him, since today he vomited a bit of yellow stuff, please Help We live in central America, have few Vets and no way of getting an endoscopy test, we already lost a loving 9 year old poodle because of a chronic gastritis that couldnot be cured!
