However, I'm so glad I found this group. My Louis is the love of my life and I feel so sad for him. He is a 6 year old beautiful ginger with golden eyes. EXCEPT about 6 weeks ago, he had an eye surgery involving a graft and we have had to give him 2 different eye drops post surgery. Just before the surgery, he started losing weight, drinking excessively, and being ravenously hungry. Vet tested and sure enough...FD. So I just started him on Purina DM and nothing else. Vet wants to see if we can control with diet and we will retest in 2 weeks after being only on this food. That is my sad tale. But I will be back on the question(s) board I'm sure. Thanks for being there!
