I apologize for not seeing this message earlier. I see it was posted almost a week ago. I hope his vet appointment turned out as good as can be hoped for. Did your vet do a complete blood work up along with a full physical examination etc? Did he/she instruct you on a healthy diet? If any of your questions haven't been answered please let me know and I will be happy to help in any way I can!!! We would also love to see some before and after photos as I am sure he will get much better looking over time with loving care.
