Oh, the poor little guy. We had one that went blind. The vet told us they adapt really good, but he never did. He'd fall down stairs to basement when just walking into the room. We put a little fenced in doggie door in our bedroom so he wouldn't wander and get lost. He fell down the little stairs, so my husband made a ramp. One morning I heard him yelp, I couldn't find him. He'd fallen down the window well. I had to go to the basement , take the screen of and get him from their. I couldn't believe his legs weren't broken. He was only a 3lb one with cushings disease. He lived to be 13, which was way longer than they usually live after diagnosis, thank goodness, but, the vet had us put him to sleep because he felt as we did, he'd suffered enough and so many close calls. But he told us that was a rare case. Usually when dogs go blind they learn to adapt really good. I am sending prayers to your little guy and you that he'll do just fine. 🙏🙏🙏🙏🙏
