Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Based on the information you have provided, I would recommend having Mighty examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I would have his blood tested and consider abdominal xrays / ultrasound as well. I hope this helps!
