My dog takes meloxydyl with her food ( for arthritis) and has done for several months. On two occasions she has developed what has been described as stress-related collitis. which has usually responded quickly to an antibiotic/ antiinflammatory injection and temporary suspension of meloxydyl. The condition has recurred once again and so I would appreciate a second opinion as to the need for the same treatment. Some ongoing stress is understandable since she recently lost her very best, ever present friend of 14 years, and she still seems to look for her.
