re: Reading dog threads on here for years.... when do you know it's time for the big sleep?

Found out today ours has bladder cancer. Sort of knew it already, but was confirmed. Doctor says she has anywhere from 1 month to maybe 6. Won't have to deal with pain, but the tumor will grow and eventually cut off her ability to pee.

We already go outside and spend 15 minutes where she pees, then thinks she has to pee for 14 minutes.

My wife is a basket case tonight. We lost our last one 2.5 years ago, this is our last one. She's 12 years old and sweet as can be. We don't have any children, so this is our baby.
