dog is blind

Question
my dog's eyes has gone blurred and she's bumping into things. my mom doesnt want me to take her to the vet so i need to know how i could help her out on my own. whats wrong with her? how can i help her see again?  

Answer
You need to take her to the vet for an examination...that is the only way to determine what is causing the blindness.  Underlying medical conditions such as diabetes can lead to cataracts and blindness, some conditions are age-related, some are genetic and others are metabolic.  I can not diagnose the problem over the internet.  The only thing you can do at home is keep the furniture the same in the house so she can learn where things are and let your voice guide her.
