She’ll be 15 next year. That’s old for a big dog. No idea how long she’ll live.
I won’t get another dog. If they died in their sleep, I’d be more likely to get another dog. No dog and I won’t have to leave my apartment. What happens when the mailbox is full? Probably get evicted before then, for not going to the office to fill out the paperwork. Or dead, from running out of food.
