Q: Last fall, our 10-year-old miniature poodle Roxie started avoiding her food and hiding her snacks. She had always been an eager eater. I found her dried-out snacks hidden in the furniture and she often made a mess removing the bigger pieces of her wet dog food from her dish. We took her to the vet because we noticed her mouth was red and thought she may have chewed on an electrical cord. She was given an antibiotic and seemed to improve, but after she finished the meds, her behavior returned. This time the vet put her to sleep to examine her and found her mouth was much worse. It was now a bright red and quite painful. A biopsy of her tongue was sent away. They found severe inflammation, but no cause.
