I just took my 5 yr. old dog (sheltie/tibetan spaniel) to the vet. He has white cloudy spots on his eyeballs. My vet says he's starting to have cataracts. Did not seem too concerned. Gave me eyedrops (steroids) to put on his eyes twice a day. Made appt. to go back in 2 weeks to check if there's been any improvement. I asked if he would go blind and she said he should be fine. After I went home, I looked up cataracts on the internet and it says the only cure is surgery. She never mentioned surgery to me. She really didn't seem like it was serious but when reading about it online it seems they eventually go blind. Is this serious? Will he probably go blind? Why didn't she mention surgery?
