My 10 y.o. Mini poodle was diagnosed with diabetes and Cushings disease, simultaneously. He’s on daily insulin injections and vetoryl for two months now but now his eyes are full of cataracts and is blind. I’m devastated and overwhelmed. He’s depressed and it breaks my heart. He’s a great dog – and I can’t afdord surgery – ! Does anyone know if dogs stay depressed or can they overcome their blindness. Desperately looking for real answers.
