So, Rogie threw up three days in a row last week. We went to the vet Saturday morning. Vet thinks it was the food change (we changed from Potato and Duck to EVO during the food scare). Vet said that Rogie might be burning through the EVO faster (since all protein) and that he's getting a sour stomach by the end of the day (all of the vomiting seemed to be done later in the day and was just bile). They x-rayed him to make sure no blockage or anything in his stomach and he was clear. His urine PH was a bit high though (blood work fine), so now on amoxicillin. Also taking a little Pepcid and we are switching back to the Potato and Duck. So far, no more throwing up. We go back next Friday for a recheck of the urine. Hopefully it was all just related to diet!
