Just talked with the vet. With him improving so much at home they want to continue the antibiotics, stop the other two meds and then have him come back next week for bloodwork to see how everything looks. He did poop yesterday so we are sending that sample in to be looked at.
Ugh, I read this and my heart sank. I love Sherbert and I hate hearing that he is not feeling well. They hide their illnesses so well, please don't beat yourself up not noticing this sooner. Please keep us posted on how the vet appointment goes. Sending you and him lots of love.
