My heart is breaking as I write this. Onyx has lost some or all of her eyesight, and quite suddenly. This was a side effect of Baytril (a side effect I was NOT warned about prior to giving Onyx these meds for treating a bladder infection and just told about today - she does not tolerate amoxicillin products so the vet put her on Baytril instead.) I'm furious at myself that I didn't ask about severe side effects and I'm furious at the vet for not telling me anything even if I didn't ask. She is seeing an opthamalogist on Monday to determine how much eyesight she has remaining, if any. Hubby and I think she may be seeing shapes but today she didn't even see Millie and walked right into her - yes, the 20 pound Millie.... I'm so sad for Onyx and I hope the opthamalogist has something good to say on Monday.
