Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! His current anorexia is likely why he has not been defecating. Anorexia for 3 days is concerning given the possible diseases that could be causing it such as pancreatitis, foreign body ingestion, inflammatory diseases, infectious diseases and even cancer, especially in an older dog. I highly recommend that you have Batista evaluated by your veterinarian for further assessment of this. Diagnostic tests are likely to include bloodwork and abdominal radiographs though other tests may be recommended based on the physical examination findings. You may try to offer Batista a palatable diet including things like boiled chicken, ground beef and white rice to entice his appetite though it is extremely important to figure out what is causing it to be able to help him. Keep water available at all times to prevent dehydration. Good luck with your boy! Will keep my fingers crossed for a speedy recovery!
