Yeah I have had the same thoughts on this too. I been doing the flip flop on this. She is scheduled to go in next week for this but I've been trying to decide for sure.Its all risky for the animal either way I suppose. She is 6 years old so hopefully she can survive. My neighbor's dog had them last year and died but he was 10 years old. One vet told me they don't even like to treat them after there 6 years old alot of them don't make it.
