Gradual weight loss in an older large breed dog is usually the result of an underlying cancer (particularly intestinal) or an underlying intestinal parasite, or pancreas disorder (exocrine pancreatic disorder) just to name a few. I would start with baseline bloodwork and a fecal exam to get a big picture as to whath is most likely the underlying cause. As long as JJ is still active, happy and clinically normal other than the weight loss, then I would consider doing the testing that he needs. Best of luck with JJ and his weight loss issues. Take care.

    Losing weight is concerning for heavy parasites or illness (which can be many many different things). The only way to know the cause is to have the pet examined by the veterinarian. I recommend to have this done within the next day or so. Bring in a fresh stool sample for testing. Best of luck.
