Your post got cut off due to character limit. The last thing that came through was "I feel like I have..." Based on the description that did come through your pet is exhibiting general signs of lethargy and lack of appetite which could indicate internal illness/disease. I would recommend having your older pet examined by your veterinarian and potentially bloodwork ran to get to a diagnosis here. Disease processes can be vague in symptoms initially but if caught early will give your pet the best chance at recovery and can limit the extent of treatment that is needed. Also making sure your pet is fed only dog food with no people food which can upset the pancreas and cause illness over time is recommended.

    This is a quite generic but concerning presentation. Differentials are many, from gastrointestinal diseases (infection/inflammations often dietary related) to any disease that can spread systemically (causing lethargy for example) like infection, and anything that can cause pain/discomfort. The approach must be logic, starting from offering different kind of food. A check up is needed if inappetence lasts for more than 24hours.
