I was back at the vet with our chocolate lab Ellie tonight. She got sick after Thanksgiving, they thought she ate something and it was stuck so the did all the a barium x ray series, blood tests, etc...nothing. She went on a chicken and rice diet (she won't eat canned food) and antibiotics and has been doing well. She got sick again today while I was at work so back to the vet we went, and they still can't find anything but are concerned about a bacterial infection. So Ellie is back on an even blander diet of cottage cheese and rice diet and antibiotics. I never thought I would be cooking for my dog! If she keeps getting sick they want to test her for IBS because they think she may have an allergy to protein (lamb, beef, chicken, etc) that she has been exposed to.
All I can say is wow.
