Anyone any serious tips we took in a rescue lab yesterday defintely blind in one eye the other eye is suspect I noticed straight away she is in season and the owner said she had been getting out so chances are definitely pregnant I think its too late for a mismate injection and too early for a spay.

If it is a cataract I would suspect it's not a hereditory one. Far more likely it's due to an injury. The only way to know for sure is to get her checked out.
